Hi, guys —

Bob replied:
James,
Yes, most are accepted, as long as they follow the same basic formula (I baptize you in the name of the Father, Son, and Holy Spirit . . .)
Groups like Jehovah Witnesses that baptize only in the name of the son are not valid.
Peace,
Bob Kirby

Hi James,
In addition to Bob's answer, Fr. Jonathan specifically noted which churches have valid and invalid Baptisms at the end of his answer.
