Acts 8:26–39

Arise and go toward the south. It is well to seek, find, and wash at noon, the one who, burning with the devotion of his heart, merited to be consecrated by God as a kind of first-fruits of the nations. In him that special saying of the Psalmist is fulfilled: Ethiopia will stretch out her hands to God.

To the way that goes down from Jerusalem to Gaza, this is desert. Not the road, but Gaza is called desert. For that old Gaza, which was once the boundary of the Canaanites near Egypt, was utterly destroyed, and another in its place was built elsewhere. This allegorically represents the people of the Gentiles, formerly deserted by the worship of God, nor cultivated by the preaching of any prophets. The way descending from Jerusalem to Gaza opens the spring of salvation; it is the Lord Jesus Christ, who says: "I am the way, the truth, and the life" (John XIV). He descended from the heavenly Jerusalem to our infirmities, and whitened the blackness of our guilt in the water of baptism.

"Now an angel of the Lord spoke to Philip, saying," etc. An angel told Philip to go to the way where queen Candace's eunuch was about to pass. The eunuch, returning from Jerusalem, where he had come to adore on account of the devotion of his mind, was sitting in his chariot, reading the passage in the prophet Isaiah where he says: "He was led as a sheep to the slaughter; and as a lamb before his shearer, he did not open his mouth", etc. Then Philip said to him: "Thinkest thou that thou understandest what thou readest?" And the eunuch made him mount the chariot and reveal to him the secrets of the Scriptures. Having received these with a faithful mind, he caught sight of some water on the way and, kindled with fervor of mind, asked to be baptized on the spot. When that was done, the Holy Ghost fell upon the eunuch, and Philip, being suddenly transported, vanished; and he was found in Azotus spreading the word of the Lord with his habitual preaching.

It seems to me, this Philip was one of the seven; for from Jerusalem he would not have gone southwards, but to the north; but from Samaria it was towards the south. "The same is desert:" so that there is no fear of an attack from the Jews. And he did not ask, Wherefore? but arose and went.

See Angels assisting the preaching, and not themselves preaching, but calling these to the work. But the wonderful nature of the occurrence is shown also by this: that what of old was rare, and hardly done, here takes place with ease, and see with what frequency!

For what reason does an angel not appear to the eunuch but instead leads him to Philip? Because perhaps he would not have believed, but would have been more terrified. For he was not like Cornelius.

"Go toward the south." He would not have been going from Jerusalem toward the south, but toward the north; but from Samaria, where Philip of the seven was residing and teaching then, the road is toward the south.

He said, however, "this is a desert," so as not to fear the oversight of the Jews.

"Not with those waters, of course, except in so far as the genus indeed is one, but the species very many. But what is an attribute to the genus reappears likewise in the species. And accordingly it makes no difference whether a man be washed in a sea or a pool, a stream or a fount, a lake or a trough; nor is there any distinction between those whom John baptized in the Jordan and those whom Peter baptized in the Tiber, unless withal the eunuch whom Philip baptized in the midst of his journeys with chance water, derived (therefrom) more or less of salvation than others. All waters, therefore, in virtue of the pristine privilege of their origin, do, after invocation of God, attain the sacramental power of sanctification; for the Spirit immediately supervenes from the heavens, and rests over the waters, sanctifying them from Himself; and being thus sanctified, they imbibe at the same time the power of sanctifying.

If Philip so "easily" baptized the chamberlain, let us reflect that a manifest and conspicuous evidence that the Lord deemed him worthy had been interposed. The Spirit had enjoined Philip to proceed to that road: the eunuch himself, too, was not found idle, nor as one who was suddenly seized with an eager desire to be baptized; but, after going up to the temple for prayer's sake, being intently engaged on the divine Scripture, was thus suitably discovered-to whom God had, unasked, sent an apostle, which one, again, the Spirit bade adjoin himself to the chamberlain's chariot.

It seems to me that this Philip was one of the seven, because otherwise from Jerusalem he would have gone not to the south, but to the north, whereas from Samaria, where Philip who belonged to the number of the seven was staying and teaching, the road goes to the south. "To the road that goes from Jerusalem to Gaza, to the one which is desert." The Angel said this so that Philip would not fear an attack from the Jews.

No trifling occasion of hidden allegory shines in the image of [the eunuch's] country: the Almighty gave full approval for Moses to unite the Ethiopian woman to himself in the bond of marriage; Scriptures reveal that he later spoke with the Lord face to face. What is there astonishing if love for the law began to grow at that time when [the law] had been joined [in marriage] to the church? Rather, the Song of Songs does not conceal the fact that the everlasting bride comes from that region: it calls her black and beautiful. She comes from the south, which burns the Ethiopian soil, to praise her Peacemaker in the mouth of Solomon, by which name [Pacificus] what Christ possesses has long been signified. She sends [the eunuch] ahead as guardian of [the church's] riches, by whose protection she might begin to bring forth her wealth. What better treasure is in her than the glory of the font? What richer gold than a wealthy faith in the heart? Finally, how rightly is her herald a eunuch! As [faith] proceeds, lust is driven off, and the chaste capture the heavenly kingdoms.

And behold, a man from Ethiopia, a powerful eunuch. He is called a man for the virtue and integrity of his mind; and not undeservedly, as he had so much zeal for the Scriptures that he did not cease to read them even on the way; and he bore so much love in religion that, leaving the royal court, he came from the farthest parts of the world to the temple of the Lord. Hence, while justly seeking an interpreter of the reading, he found Christ whom he was seeking; and, as Jerome says, found more in the desert fountain of the Church than in the gilded temple of the synagogue. For there, as Jeremiah in amazement proclaims, the Ethiopian changed his skin, that is, washed from the filth of sins, he ascended whitened from the washing of Jesus.

The queen of the Ethiopians, Candace. And in the Book of Kings, we read that the Queen of the South came from the ends of the earth to hear the wisdom of Solomon. For, indeed, it was the custom of that nation always to be ruled by women, and to call them Candace.

Who was over all her treasures. The queen of the Ethiopians, sending her treasurer to Jerusalem, designates the Church of the nations, which will offer the Lord gifts of virtues and faith. The etymology of the name also fits. For Candace can be interpreted as changed from Hebrew. It is indeed she to whom it is said in the psalm inscribed: For those who will be changed: Hear, O daughter, and see, and incline your ear, and forget your people and your father's house (Psalm 45), and the rest.

For this reason, also, Philip, when he had discovered the eunuch of the Ethiopians' queen reading these words which had been written: "He was led as a sheep to the slaughter; and as a lamb is dumb before the shearer, so He opened not His mouth: in His humiliation His judgment was taken away; " and all the rest which the prophet proceeded to relate in regard to His passion and His coming in the flesh, and how He was dishonoured by those who did not believe Him; easily persuaded him to believe on Him, that He was Christ Jesus, who was crucified under Pontius Pilate, and suffered whatsoever the prophet had predicted, and that He was the Son of God, who gives eternal life to men. And immediately when [Philip] had baptized him, he departed from him. For nothing else [but baptism] was wanting to him who had been already instructed by the prophets: he was not ignorant of God the Father, nor of the rules as to the [proper] manner of life, but was merely ignorant of the advent of the Son of God, which, when he had become acquainted with, in a short space of time, he went on his way rejoicing, to be the herald in Ethiopia of Christ's advent. Therefore Philip had no great labour to go through with regard to this man, because he was already prepared in the fear of God by the prophets.

Notice also the reason for his journey, sufficient to reveal his God-fearing attitude of mind—I mean, how long a journey he undertakes so as to pay adoration to the Lord. You see, they were still of the mind that worship was conducted in one place only and consequently traveled long distances to offer prayers there. For this reason, of course, he arrived at the place of the temple and Jewish cult so as to [offer] adoration to the Lord.

High encomiums for the man, that he, residing in Ethiopia and beset with so much business, and when there was no festival going on, and living in that superstitious city, came to Jerusalem for to worship.

An eunuch, it says, a man of great authority, under Candace, queen of the Ethiopians. For there women bore rule of old, and this was the law among them. Philip did not yet know for whose sake he had come into the desert.

The women of Ethiopia, who obeyed her, among whom one in succession was Candace: whose eunuch was over the chamber of the royal treasures. It should be known that the Ethiopians call every king's mother Candace: for the Ethiopians do not mention a king's father, but they hand them down as if true sons of the sun: and they call the mother of each one Candace.

"He rose and went." Notice the obedience. Philip did not ask or say, "Why?", but together with the command "he rose and went." "A eunuch, a court official of Candace, queen of the Ethiopians, who was in charge of all her treasure, who had come to Jerusalem to worship." Women held power in this Ethiopia; one of them by right of succession was Candace; the eunuch served as her treasurer. Note that there was no feast, yet he was traveling to Jerusalem, and that he was traveling from a city given over to superstition, and on the way he was reading, and moreover reading Isaiah, the greatest of the prophets, and furthermore reading without understanding what he read, and was so diligently occupied with his reading.

Consider, I ask you, what a great effort it was not to neglect reading even while on a journey, and especially while seated in a chariot. Let this be heeded by those people who do not even deign to do it at home but rather think reading the Scriptures is a waste of time, claiming as an excuse their living with a wife, conscription in military service, caring for children, attending to domestics and looking after other concerns, they do not think it necessary for them to show any interest in reading the holy Scriptures.

Great also is his studiousness, that even sitting in his chariot he read. Was reading the prophet Esaias. For the road was desert, and there was no display in the matter. Observe also at what time: in the most violent heat of the day.

The Spirit had enjoined Philip to proceed to that road: the eunuch himself, too, was not found idle, nor as one who was suddenly seized with an eager desire to be baptized; but, after going up to the temple for prayer's sake, being intently engaged on the divine Scripture, was thus suitably discovered-to whom God had, unasked, sent an apostle, which one, again, the Spirit bade adjoin himself to the chamberlain's chariot. The Scripture which he was reading falls in opportunely with his faith: Philip, being requested, is taken to sit beside him; the Lord is pointed out; faith lingers not; water needs no waiting for; the work is completed, and the apostle snatched away.

And the Spirit said to Philip. The Spirit spoke in Philip's heart. For the Spirit of God, as it were, appears to speak words to us, with a hidden force prompting us to do what ought to be done.

And the Spirit said unto him. Not now the Angel but the Spirit urges him. Why is this? Then, the vision took place, in grosser form, through the Angel, for this is for them that are more of the body, but the Spirit is for the more spiritual. And how did He speak to him? Of course, suggested it to him.

He was not ashamed to confess his ignorance and implored to be taught. Therefore, to him who became a learner, the grace of the Spirit was given. But as for those Jews who persisted in their ignorance; as the proverb says, "Death came upon them. For the fool dies in his sins."

I mean, when the apostle said, "Do you really understand?" and came close in his lowly condition, he was not put off, he made no objection, he did not consider himself disgraced in the way many foolish people react, often preferring to remain in unbroken ignorance through a sense of shame in admitting their ignorance and having to learn from those able to instruct them.

Observe the wisdom of Philip: he did not accuse him, not say, "I know these things exactly:" did not pay court to him, and say, "Blessed art thou that readest." But mark his speech, how far it is from harshness alike and from adulation; the speech rather of a kind and friendly man. "Understandest thou what thou readest?" For it was needful that he should himself ask, himself have a longing desire. He plainly intimates, that he knows that the other knew nothing: and says, "Understandest thou what thou readest?" at the same time he shows him that great was the treasure that lay therein.

It tells well also, that the eunuch looked not to the outward appearance of the man, said not, "Who art thou?" did not chide, not give himself airs, not say that he did know. On the contrary, he confesses his ignorance: wherefore also he learns. He shows his hurt to the physician: sees at a glance, that he both knows the matter, and is willing to teach. Look how free he is from haughtiness; the outward appearance announced nothing splendid. So desirous was he of learning, and gave heed to his words; and that saying, "He that seeketh, findeth," was fulfilled in him.

"Do you understand what you are reading?" He asks in a wonderful manner, because he neither flatters, nor praises, nor reproaches him for ignorance. But he asks in such a way as to arouse greater desire and to show that in what is being read there lies a great treasure.

Not only did he reply with restraint and continue on as well, but also he showed us the virtue in his own behavior by issuing an invitation in those words—the minister, the barbarian, seated in his chariot, inviting the man of lowly mien, despicable in attire, to mount and ride with him.

Observe again his piety; that though he did not understand, he read, and then after reading, examines. And he desired Philip that he would come up and sit with him. Do you mark the eagerness, the longing desire? But should any say he ought to have waited for Philip to speak, the answer is, he does not know what is the matter: he could not in the least tell what the other was going to say to him, but supposed merely that he was about to receive some lesson of prophecy. And moreover, this was more respectful, that he did not draw him into his chariot, but besought him.

And the eunuch confesses with complete frankness: "How can I understand, unless someone guides me?" Then he asks Philip to teach him.

See how often it stresses this point and teaches this to those who are proud and contentious: "He was a wounded man," it says, "and one who knew how to endure weaknesses; for this reason his face is turned away, bearing injuries and not much appreciated. He bears our infirmities, and he is amid sorrows on our behalf. And we thought that he was suffering sorrows, wounds and punishment. But he was wounded on account of our sins, and he became weak on account of our iniquities. In him we learned of our peace; by his bruises we were healed. We all went astray like sheep, and the Lord handed him over for our sins. And he did not open his mouth because he was mistreated. He was led off like a sheep for sacrifice, and like a lamb before his shearer, he made not a sound; thus he did not open his mouth. His judgment was removed in humility. Who will tell of his generation? For his life will be taken away from the earth. He was brought to death by the iniquities of my people. I will repay evil people on account of his burial and the rich on account of his death, because he did no wrong and had no deceit upon his lips. The Lord wishes to cleanse him of his wound. If you have given your life on account of your sins, you will see offspring with a long life. The Lord wishes to remove his soul from sorrows, to show him the light and form his mind, to justify the righteous one who serves the many well, and he will bear their sins. For this reason he will have many heirs and share the spoils with the mighty, because his soul was handed over to death and he was reckoned as one of the wicked. And he bore the sins of many and was handed over on account of their iniquities."

As a sheep led to the slaughter. Just as a sheep, when led to sacrifice, does not resist, so he suffered of his own free will. Or in a higher sense, just as the lamb was accustomed to be sacrificed at Passover, so Christ, our Passover, was sacrificed (1 Corinthians 5).

And as a lamb before its shearer is silent. He not only redeemed us with his blood but also covered us with his wool, so that we, shivering in our unbelief, might be warmed by his garment, and we might hear the Apostle speaking to us: As many of you as were baptized into Christ have put on Christ. Thus, he did not open his mouth, since in his passion he wished to answer Pilate and the chief priests briefly, and Herod not at all.

He is called a sheep; not a senseless one, but that which cleanses the world from sin by its precious blood, and when led before its shearer knows when to be silent.

But again: Whom did Philip preach to the eunuch of the queen of the Ethiopians, returning from Jerusalem, and reading Esaias the prophet, when he and this man were alone together? Was it not He of whom the prophet spoke: "He was led as a sheep to the slaughter, and as a lamb dumb before the shearer, so He opened not the month? ""But who shall declare His nativity? for His life shall be taken away from the earth." [Philip declared] that this was Jesus, and that the Scripture was fulfilled in Him; as did also the believing eunuch himself: and, immediately requesting to be baptized, he said, "I believe Jesus Christ to be the Son of God." This man was also sent into the regions of Ethiopia, to preach what he had himself believed, that there was one God preached by the prophets, but that the Son of this [God] had already made [His] appearance in human nature (secundum hominem), and had been led as a sheep to the slaughter; and all the other statements which the prophets made regarding Him.

And Philip ran thither to him, and heard him reading; even the fact of his running, showed that he wished to say something. And the place of the Scripture which he read was this: As a sheep He was led to the slaughter. And this circumstance, also, is a token of his elevated mind, that he had in hand this prophet, who is more sublime than all others. Philip does not relate matters to him just as it might happen, but quietly: nay, does not say anything until he is questioned.

He was led as a sheep to the slaughter; and like a lamb dumb before his shearer, so opened He not His mouth: in His humiliation His judgment was taken away: and who shall declare His generation? for His life is taken from the earth. Observe how it is Providentially ordered. First he reads and does not understand; then he reads the very text in which was the Passion and the Resurrection and the Gift.

From this point the voluntary act of the Savior is signified in the trial of those being allotted with. For as a sheep led to sacrifice, or a lamb before the one who shaves it (forced and subdued, it does not even have the capacity to moan), so he was silent willingly in his suffering. (see Isa. 53:7-8) [THEODORE OF HERACLEA]

"Like a sheep, He was led to the slaughter." The meaning of the words cited is very clear, because at a certain time sheep are led away for shearing and the shepherds lay upon them the instruments of shearing, yet the sheep endure this and do not attack those who do it. So also Christ, enduring reviling, did not repay reviling for reviling.

In his humiliation, his judgment was taken away. Because the judge of all did not find truth in judgment, but, without any fault, was condemned by the clamor of the Jews and the voice of Pilate.

Who shall declare his generation? Either it is to be understood of his divinity that it is impossible to know the mysteries of his divine birth, of which the Father speaks: I have begotten you from the womb before the morning star (Psalm 110); or of the Virgin's birth, which can be explained with difficulty. To Mary, seeking the reason, it is said through the angel: The Holy Spirit will come upon you. So either the angel or the evangelist should declare only the sacraments of his birth, who is a rare narrator.

For his life will be taken from the earth. So that he would live not on earth, but in heaven.

The phrase, "In his humiliation his judgment was taken away," indicates the unlawful judgment that was made against him, the truth of which was hidden. [THEODORE OF HERACLEA]

And the question, "Who will declare his generation?" when brought forward shows him to be without genealogy. For he was indeed without genealogy as God, and born according to the flesh as one recorded. That is, who will be able adequately to relate in words the trial that occurred after the resurrection, and his noble worth, which the trial of those managed by him demonstrated? He was subjected to death, and by his grace he gave life to all into incorruption, and redeemed by faith. [THEODORE OF HERACLEA]

Then he says, "For his life is taken from the earth," that is, it is lifted up, and his life is higher than the things on earth, that is, his society. It is also taken in another sense, and his life is above all, that is, the existence of the Only-Begotten, when thought of apart from the flesh and not yet become toward us. [CYRIL]

For his life, having voluntarily descended unto death, was taken up from the earth, was raised upward, and ascended above the heavens (Ps. 8:3), because he was a king of glory, and his life by nature, and Lord of hosts; even if because of the providence concerning us and the voluntary self-emptying, who endured on earth the dishonor and obscurity due to his suffering, this may reasonably be ascribed to him because of the flesh united to him according to hypostasis and inseparably, with respect to which was the passion, and therefore came the dishonor mentioned above; bold as it was on the part of God regarding the incarnate one, yet unable to touch the impassible, which is impossible. [FROM THE TREATISE TO JULIAN]

"In His humiliation His judgment was taken away." He indicates the unlawful judgment against Him, carried out at a time when the truth was hidden. "But who shall declare His generation?" That is, His high dignity revealed after the resurrection, the proof of which is what He accomplished in the work of the divine economy. Who will be able to express in words, when one considers: "Who is this and what manner of Person, and moreover the Only-Begotten Son of God, endured all this?" "His life is taken from the earth." Instead of the expression "His life is taken away and elevated above the earthly," that is, the course of activity and existence of the Only-Begotten, when He is contemplated apart from the flesh and no longer as being among us.

And the eunuch answered Philip, and said, I pray thee, of whom speaketh the prophet this? of himself, or of some other man? That he should at all know either that the Prophets speak in different ways about different persons, or that they speak of themselves in another person-the question betokens a very thoughtful mind.

"I ask you to tell me, of whom does the prophet say this?" To know that the prophets sometimes speak about others as well, or about themselves in another person, because this is what his question shows — the quality of a very observant man.

But Philip opening his mouth, etc. Philip interpreted means 'the mouth of a lamp,' and it is a beautiful sense that the mouth of a lamp opened its mouth, while it brought forth the obscure things of prophecy into the light of knowledge. Although these circumlocutions according to history could signify that his speech at that time would be somewhat longer.

Then Philip opened his mouth, and began at the same Scripture, and preached unto him Jesus. It is likely he had heard that He was crucified, and now he learns, that His life is taken away from the earth, and the rest that He did no sin, nor deceit in His mouth: that He prevailed to save others also: and who He is, Whose generation is unutterable.

Therefore this is Jesus, and Philip proclaims this Scripture to the eunuch, that it is fulfilled in him; and the eunuch, having believed and immediately baptized, was sent to the regions of Ethiopia, proclaiming that which he himself had believed: that there is one God foretold by the prophets, and that this One's Son has already been made present according to humanity, and was led as a sheep to the slaughter, and the other things which the prophets say about him. And here the prophecy is fulfilled that says, "Ethiopia will hasten her hand to God." (Ps. 68:31) [EUSEBIUS]

They came to a certain water. Even today there is a village called Bethsoro in the tribe of Judah, on the twentieth milestone of those going from Chebron of Elias. Near it, a fountain bubbling up at the roots of a mountain is absorbed by the soil from which it springs. In this place, the eunuch was baptized by Philip.

Who prohibits me from being baptized? And he commanded the chariot to stop, and the rest. Here another translation according to the Greek exemplar has a few more verses where it is written: Behold water, who prohibits me from being baptized? But Philip said to him: If you believe with all your heart, you will be saved. And responding, he said: I believe in Christ, the Son of God. And he commanded the chariot to stop, and the rest. I believe, therefore, that our own interpreter initially translated these verses as well, but they were later omitted due to the fault of the scribes.

That he who believes can immediately obtain (i.e., pardon and peace).]In the Acts of the Apostles: "Lo, here is water; what is there which hinders me from being baptized? Then said Philip, If thou believest with all thine heart, thou mayest."

And as they went on their way, they came unto a certain water: and the eunuch said, See, here is water; what doth hinder me to be baptized? Mark the eager desire, mark the exact knowledge. Then, it says, they came to a certain water, and he said, Lo, here is water. Again, of his own accord he requests, saying, What doth hinder me to be baptized? And see again his modesty: he does not say, Baptize me, neither does he hold his peace; but he utters somewhat midway betwixt strong desire and reverent fear, saying, What doth hinder me?

Do you observe that he has the doctrines of faith perfect? For indeed the Prophet had the whole, Incarnation, Passion, Resurrection, Ascension, Judgment to come. And if he shows exceeding earnestness of desire, do not marvel. Though about to return home, he did not say to himself: "I am going back to my country, there let me receive baptism;" those cold words which most men use! No need had he of signs, no need of miracles: from the Prophet merely, he believed.

It should be observed that great zeal existed among Christians entirely for the sensible baptism. Since what is given is twofold, sometimes through water, sometimes in the Holy Spirit and fire, they did not despise the more bodily one on account of the superiority of the baptism in the Spirit. For this also contributes to salvation and to the resurrection of the body. [DIDYMUS]

"Behold, water; what hinders me from being baptized?" See how prudently he acts. First he reads and does not understand, then he reads the same prophecy; it contains the teaching about the suffering, the resurrection of Jesus Christ, and the bestowal of the grace of the Holy Spirit. Then he asks to be baptized; Philip explains to him in order, beginning from this prophecy. And having been uplifted by his readiness, he is gradually led to baptism. But he did not say "baptize me," but rather: "what hinders me?" By this question he showed a strong desire to receive baptism.

This same Philip, who had baptized people, and the Holy Spirit had not come upon them until the apostles had come along and laid their hands on them, baptized the eunuch of queen Candace who had been worshiping in Jerusalem, and on his way back from there he was reading the prophet Isaiah in his chariot and not understanding it. Philip was prompted to approach the chariot, and he explained the reading, insinuated the faith, preached Christ. The eunuch believed in Christ and said, when they came to some water, "Look, here is water; who is to prevent me being baptized? Philip said to him, "Do you believe in Jesus Christ?" He answered, "I believe that Jesus Christ is the Son of God." And immediately he went down with him into the water. Once the mystery and sacrament of baptism had been carried out, since there was no expectation of the apostles coming as on the previous occasion, so that no one should think the gift of the Holy Spirit was at the disposal of mortals, the Holy Spirit came immediately.

And he commanded the chariot to stand still: and they went down both into the water, both Philip and the eunuch; and he baptized him. Be ashamed, all ye as many as are unbaptized.

The Spirit of the Lord snatched Philip away. There are some who testify that an angel did this in the Holy Spirit, as Jerome reports.

And when they were come up out of the water, the Spirit of the Lord caught away Philip, that the eunuch saw him no more: and he went on his way rejoicing. But why did the Spirit of the Lord bear him away? Hereby the occurrence was shown to be more wonderful. Even then, the eunuch did not know him. Consequently this was done, that Philip might afterwards be a subject of wonder to him. For, it says, he went on his way rejoicing.

And when they were come up out of the water, the Spirit of the Lord caught away Philip; in order that the occurrence might be shown to be of God; that he might not consider it to be merely man. And he went, it says, on his way rejoicing. This hints, that he would have been grieved had he known: for the greatness of his joy, having had the Spirit also vouchsafed to him, he did not even see things present.

It was well and expedient therefore that the Spirit caught Philip away; else the eunuch would have desired to go with him, and Philip would have grieved him by declining to comply with his request, the time being not yet come. So that had he known him, he would not have been so delighted.

The Spirit seized Philip, for though the eunuch had indeed wished to converse, Philip, refusing and denying because it was not yet time, nevertheless would have grieved him. Philip himself also gained very much profit, seeing that what he had heard in Ezekiel and Habakkuk was fulfilled in him. [CHRYSOSTOM]

"An Angel of the Lord caught Philip away." An Angel takes him, thereby adding greater wonderousness to what had happened, and at the same time bringing joy to Philip as well, that he was deemed worthy of the same things as the prophets, such as Habakkuk. It was good that he was taken from the eunuch, because the eunuch would have asked Philip to go with him, and Philip would have grieved him if he had refused due to the demands of circumstances.
