If a Protestant wants to marry a Catholic, and his conscience does not protest against it, he may sign the promise in regard to the children. But if the Protestant really believed the Catholic faith to be evil, and that his personal religion was the only true religion, then he has no right to promise that any of his children will be Catholics. He should abandon the marriage rather than thus violate his conscience. He should demand that the children be brought up in his faith. But then of course a dead-lock would result. He would have to refuse compromise, and as the Catholic is also obliged to refuse marriage unless the written promise is given, the marriage would be cancelled. It is better to part with a human being than to part with loyalty to conscience in so grave a matter.
