Thank you all for your feedback. It has been something that had bothered me for a while. The candidates we wanted as godparents weren’t Catholic, but they were very close in their relationship with God and I felt although they didn’t have Catholic upbringing, they would at least give encouragement to my child for enriching his faith, in which by the way my wife and I are raising to be Catholic.
The baptism was in valid form.
I’d like to discuss it with my priest, but he was the one who gave the baptism and I feel bad having to go up to him to pretty much say, “Hey, we lied to you about our godparents by the way.” But I guess I should really just talk to him about it anyways right?
The bottom line was mainly if I should I go to confession or is this really not a serious matter?
