EWTN Catholic Q&A
Confession by non-Catholics
Question from Katie on 04-07-2013:

Can you receive confession if you are not Catholic?

Answer by Catholic Answers on 04-10-2013:


You can if you are a baptized Christian and meet certain conditions, the most usual being immediate danger of death or impending reception into the Church. Unbaptized people, whether or not they self-identify as a Christian, may not receive confession. Baptism is the gateway to the other sacraments, and so an unbaptized person would first have to be baptized.
