I would not take Tertullian’s pronouncement as valid. He was declared, and died a Heretic.
I believe the Catechism of the Catholic Church still him a father of the church does it not? So you would say that one of the fathers of the CC was a heretic? Yet doesnt the CC also claim unanimous consent? Are you saying that not only do they not have unanimous consent amongst the various “fathers” but that they don’t even have it in each of the “fathers”?
