Infant baptism is a heresy against christianism, and against the teaching in the Holy Scriptures (which are the only authority for the church under God). Considering what baptism is, an infant is no more capable of baptism than an animal. This is because baptism is not only washing with water, but it is the baptism of the Spirit, the confession of the mouth, and the washing with water. How can any man, without committing a heresy and folly, wash with water which is the least and last of baptism, one that is not baptized with the spirit and cannot confess with the mouth or how is it baptism if one is only washed?
It’s obvious that an infant cannot be baptized with the Spirit, 1 Peter 3:21 where the Apostle said that the baptism of the Spirit is the question of a good conscience to God. Because it’s obvious that an infant cannot confess, and therefore no purging of the heart, which is proper for sinners, so it should follow that infant baptism is folly and means nothing.
Once again, it is in repentance, as John’s baptism was the baptism of repentance. Infants have no repentance and therefore cannot have the baptism of repentance. That infants cannot have repentance is evident, seeing repentance is knowledge of sin by the Law, sorrow for sin by the gospel, mortification of sin and new obedience, all which are as much in the basin of water, as in the infant is baptized.
“Indeed the Lord saith, forbid them not to come unto me. Therefore, let them come to Christ but let them come when they are grown, when they learn, and when they are taught to what they come. Let them by baptism be made Christians when they can know Christ by instruction.” (eush. Evvlesi. Hist. Lib)
