Pauline Privilege: natural marital bond between two unbaptized persons is dissolved by the fact that one of the parties receives baptism and enters a new marriage.
For the Pauline privilege to be invoked, it must be proven that both parties were unbaptized at the time of the marriage and that only one party has received baptism. In this case, it must be clear that the other party does not wish to receive baptism and wishes to depart from marital life (or wishes to remain departed if the parties are already civilly divorced). The party who has been baptized may not, however, be the cause of the separation after the baptism has taken place.
**Petrine Privilege **: also know as Privilege of the Faith is a dissolution of marriage in which at least one of the parties to a previous marriage was non-baptized throughout the entire duration of their married life. If the petitioner is the non-baptized party or was baptized in another Christian church, he or she must either wish to be baptized or received into the Catholic Church, or seek to marry a baptized, practicing Catholic. If the petitioner is a baptized Catholic who was married to a non-baptized person, he or she must either wish to enter into marriage with a baptized Christian, or promise to enter marriage with a baptized Christian in the future. Privilege of the Faith cases involve a special petition to the Holy Father and are decided in Rome.
