“Infant baptism is not in Scripture, and against that statement, there is no evidence—there is no refuting of that statement. Scripture nowhere advocates infant baptism. It nowhere mentions infant baptism. It doesn’t exist in the Bible; there is no example of it, there is no comment on it, it’s not there. It is therefore impossible to prove that infant baptism is valid, from the New Testament. It’s impossible to support it from the New Testament or for that matter, from the Old Testament.” (John MacArthur A Scriptural Critique of Infant Baptism)
