Canon 1086

Can. 1086 §1. A marriage between two persons, one of whom has been baptized in the Catholic Church or received into it, and the other of whom is not baptized, is invalid.

Can. 1086 §2. A person is not to be dispensed from this impediment unless the conditions mentioned in cann. 1125 and 1126 have been fulfilled.

Can. 1086 §3.
