Bede : And he ordered them to be baptized in the name of Jesus Christ. And the circumcised believers who had come with Peter were amazed because the gift of the Holy Spirit had been poured out even on the Gentiles. Since the rule of the Church is that believers are to be baptized in the name of the Holy Trinity, it is asked how Luke, throughout the entire text of this book, testifies that baptism is given only in the name of Jesus Christ. Blessed Ambrose resolved this by saying that the mystery is fulfilled through the unity of the name. For whether you say Christ, you have designated both God the Father, who anointed the Son, and the very Son who was anointed, and the Spirit by whom he was anointed; for it is written: Jesus of Nazareth, how God anointed him with the Holy Spirit; whether you say Father, and his Son, and Spirit, you indicate equally in the mouth if you even comprehend it in your heart; or if you say Spirit, you name both God the Father, from whom the Spirit proceeds, and the Son, because the Spirit is also of the Son. Hence, that authority may also be joined to reason, Scripture indicates that we can rightly be baptized in the Spirit as well, with the Lord saying: But you shall be baptized with the Holy Spirit (Acts 1:5). And the Apostle says: For in one Spirit we were all baptized into one body (1 Cor. 12:13). Elsewhere: It is particularly fitting for us to be baptized in the name of the Lord Jesus Christ, since as the Apostle says: For as many of you as were baptized into Christ Jesus were baptized into his death, etc. (Rom. 6:3). — Commentary on Acts John Chrysostom : "And he commanded them to be baptized in the name of Jesus Christ." After he has cleared himself, then, and not before, he commands them to be baptized: teaching them by the facts themselves. Such was the dislike the Jews had to it! Therefore it is that he first clears himself, although the very facts cry aloud, and then gives the command. "Then prayed they him" - well might they do so - "to tarry certain days:" and with a good courage thenceforth he does tarry. — Homily on Acts 24
