A sponsor is a man or woman who is an intentional disciple of Jesus Christ in the Catholic Church and who mentors a candidate seeking to become Catholic. One cannot be a sponsor in the Catholic Church unless the follow baseline conditions are met:
This means that the person you want to be your sponsor must be a practicing Catholic, cannot be engaging in notorious sin, and cannot have taken public positions in opposition to Catholic faith and morals. If married, the sponsor must be married within the Catholic Church. A person who is not Catholic, or who is not living in a way consistent with the faith obviously cannot provide the example that is essential to being a witness and sponsor.
