What credal truth does he deny? MJ flunked Catholic vocabulary. Of course, all western Catholics are heretic because we believe in a bad translation of the Creed that has the Spirit proceed from the Father and the Son. It was not adopted that way at Nicea. We think our reasoning is good, but it is still heretical as the agreement is the other way officially and there is no way of actually knowing the truth except by dying and maybe not even then.
