John 4:2: (Though Jesus himself baptized not, but his disciples,)
Contradiction with Acts 10:47-48
Here, Peter commands people to be baptized even after they received the Holy Spirit, implying baptism is not immediate, unlike the implication of immediate action in 1 Corinthians 1:16.
Acts 10:47-48: Can any man forbid water, that these should not be baptized, which have received the Holy Ghost as well as we?

Acts 19:4-5: Then said Paul, John verily baptized with the baptism of repentance, saying unto the people, that they should believe on him which should come after him, that is, on Christ Jesus.
