Apostasy

The obstinate post-baptismal denial or obstinate doubt of a truth that must be believed with divine and Catholic faith. Heresy differs from apostasy, the total repudiation of Christian faith, and schism, refusal of submission to the pope or communion with those subject to him.

The refusal of submission to the Roman Pontiff or of communion with members of the Church subject to him. Schism concerns ecclesial communion and authority and is distinguished canonically from heresy and apostasy.
