I have heard it said than anyone can validly baptise as long as it's in the name of the Father, Son, and Holy Spirit, is this true?
And if it is, what instances would this be neccesary?
For instance: Me and my friend are walking down the road and have been talking about the Catholic faith for some time and he is 100% sure that he wants to become Catholic, however, he was never baptized. So we come up on a pond and I baptize him, is it valid? I'm going to assume he knows he has to go through RCIA and be confirmed. Or would he need to be re-baptized in the Church?
