Our godchildren were rebaptized in the baptist church after their parents’ divorce. Do we still have an obligation to them if their parents are no longer interested in them being Catholics?
Can. 872 Insofar as possible, a person to be baptized is to be given a sponsor who assists an adult in Christian initiation or together with the parents presents an infant for baptism. A sponsor also helps the baptized person to lead a Christian life in keeping with baptism and to fulfill faithfully the obligations inherent in it.
Godparents in infant baptism are chosen by the parents to assist “the one baptized in living the Christian life and in fulfilling faithfully the obligations flowing from it” (*New Commentary on the Code of Canon Law * pg. 1061). Even though the parents have abdicated their parental responsibilities to raise their children in the faith, your obligation to remain faithful to your responsibility as a godparent remains.
Make every effort to stay in contact with the children. In addition to sending them birthday and Christmas cards, perhaps you can send them baptismal birthday cards in celebration of their baptism. But, more importantly, your faithfulness to prayer, your sacrifices and your example of holiness will help bring this family back to the one true faith.
God bless you. You are in my prayers.
