BaptismAnswered
Is a godparent who has left the faith still the child's godparent?
TL;DR
Robert Sungenis answers that you have to go to the church and report it officially, naming the godparent who has left the faith and asking for a replacement. He says the church will allow it: you bring your candidate, they test the person, and then they accept it, but it has to be done officially.
A viewer asks whether a godparent who has left the faith is still the godparent.
Answer
You have to go to the church and tell them officially, for example that John Smith, the godparent, has left the faith, and that you need a new godparent. The church will allow you to do that; you bring your candidate to them, they test the person a little bit, and then they will accept it. But you have to go to the church and get it done officially.
