1 Corinthians 1:14 (The Message)
13-16I ask you, "Has the Messiah been chopped up in little pieces so we can each have a relic all our own? Was Paul crucified for you? Was a single one of you baptized in Paul's name?" I was not involved with any of your baptisms—except for Crispus and Gaius—and on getting this report, I'm sure glad I wasn't. At least no one can go around saying he was baptized in my name. (Come to think of it, I also baptized Stephanas's family, but as far as I can recall, that's it.)
Paul's observation may lend insight as to why Jesus let His disciples baptize. Someone baptized personally by Jesus might lord it one who was not. Jesus knows our frailties.
