When they had believed. That is the miracle whereof I spake because they heard Philip, who were altogether made astonied with the illusions of Simon; in that they were made partakers of the heavenly wisdom who were blockish and dull. So that they were, after a sort, brought from hell to heaven. Whereas baptism followed faith, it agreeth with Christ's institution, as concerning strangers, (Mark 16:47 [sic],) and those which were without. For it was meet that they should be engrafted into the body of the Church before they should receive the sign; but the Anabaptists are too foolish, whilst they endeavor to prove by these places that infants are not to be baptized. Men and women could not be baptized without making confession of their faith; but they were admitted unto baptism upon this condition, that their families might [1] be consecrated to God; for the covenant goeth thus: "I will be thy God, and the God of thy seed," (Genesis 17:7.)

But when they believed Philip,.... Though they had been carried away so long with this deceiver, and had been so much attached unto him, and held in admiration of him; yet when Philip came and preached Christ unto them, such was the power that attended his ministry, and such the efficacy of divine grace that was exerted, that they not only gave heed unto him, but believed what he said:
preaching the things concerning the kingdom of God; concerning the kingdom of the Messiah, the Gospel dispensation, the doctrines and ordinances of the Gospel; and concerning the kingdom of grace, which is spiritual and internal, and which lies not in external things, as meat and drink, but in righteousness, peace, and joy; and concerning the kingdom of glory, the meetness for it, which lies in regenerating grace, and the right unto it, which is the righteousness of Christ:
and the name of Jesus Christ; concerning the person of Christ, as the Son of God: and the offices of Christ, as prophet, priest, and King; and the virtue of his blood, righteousness, and sacrifice, for pardon, justification, and atonement: the Vulgate Latin, Syriac, and Ethiopic versions read this clause, "in the name of Jesus Christ": and connect it with the following words,
they were baptized, both men and women: that is, when, they heard Philip preach the Gospel, and believed in Christ, the sum and substance of it, and made a profession of faith, they were of each sex, both men and women, baptized by immersion, in the name of Jesus Christ.
