Commentary on the Acts of the Apostles John Calvin
John Calvin doth not, nor shall not, always so fall out, that all those which hear the word with their outward ears, do or shall also receive the Spirit; and the ministers do seldom light upon such hearers as Peter had, who are willing, with one consent, to follow God. Yet he bringeth to pass that all the elect feel in themselves the consent of the external word, and of the secret power of the Spirit.
45. The faithful were astonished. He calleth them faithful who were as yet possessed with a wicked error. So the Lord doth not by and by wipe away all clouds of ignorance from his, and yet they do not darken the praise of faith before God, because he pardoneth errors and doth vouchsafe to favor it, as if it were pure and plain. And yet it is a wonder, that seeing they knew that Peter was sent of God, they would now be amazed, as at some strange and new thing, because God giveth the grace of his Spirit to those to whom he would have Christ now preached; but the sudden change is the cause of this, because, whereas God until that day had separated the Gentiles from his people as strangers and aliens, he doth now favor them both alike, and lifteth them up into the like degree of honor. Although we be also taught by this example, how hard a matter it is for us to wind out ourselves out of our errors once conceived, especially when they are of any continuance.
46. For they heard them. He expresseth what gifts of the Spirit were poured out upon them, and therewithal he noteth the use; to wit, that they had variety of tongues given them, so that they did glorify God with many tongues. Also, it may be gathered out of this place, that the tongues were given them not only for necessity, seeing the gospel was to be preached to strangers and to men of another language, but also to be an ornament and worship to the gospel. But ambition did afterward corrupt this second use, forasmuch as many did translate that unto pomp and vain glory which they had received to set forth the dignity of the heavenly wisdom, as Paul doth sharply reprove this fault in the Corinthians. Therefore, no marvel if God took away that shortly after which he had given, and did not suffer the same to be corrupted with longer abuse.
47. Peter answered. Peter reasoneth from the thing to the sign; for, seeing that baptism is an addition or appurtenance of the spiritual grace, he which hath received the Spirit is also apt [fit] to receive baptism; and this is the (most) lawful order, that the minister admit those unto the receiving of the outward sign whom God hath testified to be his children by the mark and pledge of his Spirit; so that faith and doctrine are first. And whereas unlearned men infer thereupon that infants are not to be baptized, it is without all reason. I grant that those who are strangers from the Church must be taught before the sign of adoption be given them; but I say, that the children of the faithful which are born in the Church are from their mother's womb of the household of the kingdom of God. Yea, the argument which they use preposterously against us do I turn back [retort] upon themselves; for, seeing that God hath adopted the children of the faithful before they be
