Bede : They sent Peter and John to them. Arator beautifully explains this: Peter often makes John his companion, because the Church favors the virgin. — Commentary on Acts John Chrysostom : "Now when the Apostles which were at Jerusalem heard that Samaria had received the word of God, they sent unto them Peter and John: who, when they were come down, prayed for them, that they might receive the Holy Ghost." And yet great signs had been done: how then had they not received the Spirit? They had received the Spirit, namely, of remission of sins: but the Spirit of miracles they had not received. "For as yet He was fallen upon none of them: only they were baptized in the name of the Lord Jesus. Then laid they their hands on them, and they received the Holy Ghost." For, to show that this was the case, and that it was the Spirit of miracles they had not received, observe how, having seen the result, Simon came and asked for this. — Homily on Acts 18 John Chrysostom : Why had not these received the Holy Ghost, when baptized? Either because Philip kept this honor for the Apostles; or, because he had not this gift to impart; or, he was one of the Seven: which is rather to be said. Whence, I take it, this Philip was one of the Apostles. But observe; those went not forth: it was Providentially ordered that these should go forth and those be lacking, because of the Holy Ghost: for they had received power to work miracles, but not also to impart the Spirit to others: this was the prerogative of the Apostles. — Homily on Acts 18 John Chrysostom : But how came it that in the case of the Samaritans this did not happen, but, on the contrary, neither before their baptism nor after it was there any controversy, and there they did not take it amiss, nay, as soon as they heard of it, sent the Apostles for this very purpose? True, but neither in the present case is this the thing they complain of; for they knew that it was of Divine Grace: what they say is, Why didst thou eat with them? Besides, the difference is not so great for Samaritans as it is for Gentiles. — Homily on Acts 24
