Usually when the issue of mixed marriages come up, most people say that one of the requirements is that both spouses agree to raise the children Catholic. But, unless I am misunderstanding the relevant section of Canon Law, this is not the case. Only the Catholic spouse must promise to raise the children the Catholic. The other must merely be informed of this fact.
Canon 1125.1 the catholic party is to declare that he or she is prepared to remove dangers of defecting from the faith, and is to make a sincere promise to do all in his or her power in order that all the children be baptised and brought up in the catholic Church; Canon 1125.2 the other party is to be informed in good time of these promises to be made by the catholic party, so that it is certain that he or she is truly aware of the promise and of the obligation of the catholic party.
Am I missing something?
