The Catechism of the Catholic Church states, "Incredulity is the neglect of revealed truth or the willful refusal to assent to it. Heresy is the obstinate post-baptismal denial of some truth which must be believed with divine and Catholic faith, or it is likewise an obstinate doubt concerning the same; apostasy is the total repudiation of the Christian faith; schism is the refusal of submission to the Roman Pontiff or of communion with the members of the Church subject to him" (CCC 2089).

Yep. Proclaiming the Holy Father's "confusion" in his teachings of the Catholic faith is a heresy.

Very good.
