In Acts 2:38f, God commands the penitent: “Be baptized every one of you…, for the promise is unto you and to your children!” Commented Calvin: “This passage therefore sufficiently refutes the Anabaptists, who deny baptism to the children of the faithful while they are still infants, as though they were not members of the Church…. This gross presumption is of no profit to them!” And on Acts 11:16f: “Those who are opposing infant baptism, are waging war against God!”
According to the Westminster Larger Catechism 124-130, the Fifth Commandment requires fathers and mothers not to commit “sins” by “the neglect of the duties required of them” — such as that of bringing their children to be baptized. “Second Kings 5:13; Ephesians 6:4; Deuteronomy 6:6f; Ezekiel 34:2-4.”
