It's Johns baptism. There is no evidence that Jesus always even shows up for that. Magic is not a part of real Xian faith. Judaism has the ''mikveh'', Johns baptism is clearly a type of Mikveh, and it was meant for washing away sins, not salvation. Paul asked people, if they had been baptized by water, they said yes, then Paul proceeds to give them the real baptism of the Spirit, which was without water at all.
Having your own beliefs is fine, but this stuff is actually important to some people who might be joining the faith, the Scripture explicitly does not combine the baptism of water with the baptism of Spirit, it EXPLICITLY separates them.
