So the "pope" not only allowed a modernist sect to occupy the Church but he championed it and led the way. And you recognize this false antipope as the true pope of the Catholic Church (without actually being fully subject to him, of course) and you count this as a virtue? And on top of that you think it is simple to understand how all this could be? Wow!
I didn't say anything about the pope allowing a modernist sect to occupy the Church. I said that God allowed a modernist sect to occupy the Church. Unless perhaps you believe that the pope is supposed to be the same thing as God when he's a valid pope? But yes, the Vll popes have allowed a modernist sect to occupy the Church, but that's another subject. You didn't address the idea of God allowing a modernist sect to occupy the Church.
I'm not sure that it's considered a virtue for a Catholic to believe that there's a Pope of the Catholic Church. It may indeed be a virtue to believe as such. It's just what Catholics have always believed. Just a few days ago was the feast day of St. Linus, pope and martyr. As you know, he succeeded St. Peter. We have always had successors to St. Peter, since the beginning. For nearly two thousand years. Having a Pope is one of the main things that separates us from the protestants.
It is simple to understand that we still believe that there's a pope, but that we are subject to God first. See Stubborn's post that precedes mine. He sums it up quite well.
