Man, you're a propaganda machine today. Could you reveal your sources so we can verify who's saying this stuff? Your sources do not say who actually wrote the piece. Only where they claim to have gotten the info.He, then, who before was silent, to teach us that we ought not to repeat the words of the impious, this one, I say, when he heard,But who do you say I am, immediately, not unmindful of his station, exercised his primacy, that is, the primacy OF CONFESSION, not of honor; the primacy OF BELIEF, NOT OF RANK. This, then, is Peter, who has replied for the rest of the Apostles; rather, before the rest of men. And so he is called the foundation, because he knows how to preserve not only his own but the common foundation...Faith, then, is the foundation of the Church, for it was not said of Peters flesh, BUT OF his faith, that the gates of hell shall not prevail against it. But his confession OF FAITH conquered hell. And this confession did not shut out one heresy, for, since the Church like a good ship is often buffeted by many waves, the foundation of the Church should prevail against all heresies

I say this because, often on these radial sites, they'll quote something a Catholic wrote 200yrs ago, out of context to try and imply its official Church teaching.
