Also, the wedding must take place in a Catholic Church. A flight deck won’t do.
Since the human is not Roman Catholic (since all Cylons are monotheists and hence possibly Catholic, and humans are of the Lords of Kobol polytheistic religion, and so cannot be Catholic by definition), then he or she must agree to raise any children Catholic. And if the Catholic party is to get married at either the Lords of Kobol temple or at a Cylon church which is not Catholic, then they must get an exemption from the Catholic bishop who diocese includes deep space.
