Phil,
You cited one church father.
No St. Thomas cites St. Augustine, but he says that "all agree" i.e. All the Church Fathers:
I answer that, All are agreed in saying that original sin was remitted in circumcision.
Phil:
Your appeal to authority and labeling mean very little at this point. They are your "opinion". I will certainly retract my claim that it is heresy, being that Augustine certainly appears to agree with Aquinas. But, I will not retract my claim that it is erroneous.
In discussions about the Catholic faith, authority means everything.
re. My "opinion": St. Thomas cites St. Augustin and says it is also the opinion of "All".
re. "Erroneous"; Here is where you would have to cite a Doctor of the Church; Papal Encyclical or Manual of Dogmatic Theology; otherwise its just your opinion; and can be dismissed.
Phil:
Concerning the fathers, "llkewise it decrees that the works and treatises of all the orthodox fathers who in no way have deviated from the society of the holy roman church ... ought to be read
Great! I agree, lets see some quotes from these Church Fathers on the subject under discussion.
Phil,
Finally, St. paul says, "Prove...all things, hold that which is good".
That is a far cry from what you make of my opposition.
Good, how are we going to "prove what is good" except through the authority of the Church?
Re. Authority of St. Augustine: Yes, St. Augustine is a great authority; but he is not to be preferred over the teaching of the Magisterium; but again, you haven't quoted from either St. Augustine, from some other Father of the Church, or from the teachings of the Magisterium; you have basically been 'freelancing' here.
Phil,
But, a material heretic who is catholic and in the church is not by the very fact of their material heresy cast out of the church. It requires a formal declaration. If it requires a formal declaration in the church, it requires a formal declaration outside of the church. You have yet to step up to the plate in that regard, and that is what kicked this debate off.
Yes, I cited Mistici Corporis and, again you gave it your own "spin" without citing where you came up with this. I can cite from a Manual of Dogmatic Theology to substantiate my view of it (plus the obvious sense of the words). But I'm not getting anything back from you in this regard of equal value.
Phil,
You cannot substantiate your claim that a non catholic sectarian pastor is ipso facto a formal heretic.
Yes, I concede that I will try to find something on this.
Phil:
"Once a catholic, always a catholic" is an error/heresy.
Fine, I'm not agreeing or disagreeing, but please substantiate your claim.
