Give him time. PM has has a healthy interest in these discussions and a commendable willingness to seek an understanding the deposit faith.
Despite his hardline skepticism, I don't think I've ever seen him completely reject any major tenant of the faith.
The Body of Christ has its own way of making "attachments". That's why we call it mystical.

You know AAABEST, I'm 3/4ths catholic. I would have been a catholic if I had been born in the first 15 centuries.
To me it's not about Catholic/Protestant/Orthodox, it's about people really knowing God and really loving Christ. I think you can have a badly truncated theology and still overcome a lot if you really love Christ and love others for his sake. Ultimatley we will be judged not on what we were able to figure out but on how we treated those around us.
I know what Christ has done for me. I know how he radically changed my life (I was a very bad person) and how he continues to bear with me and forgive and help me - wretched sinner that I am. I want other to know that.
The whole Catholic/Protestant/Orthodox smacks of "I'm of Peter, I'm of Paul, I'm of Apollos." (I know it's more complicated than that.) I come back to this...
"If anyone imagines that he knows something, he does not yet know as he ought to know. But if anyone loves God, he is known by God."
A large part of what motivates me is the fact that there are multitudes in both Catholic and Protestant churches for whom Christianity is merely their "religion". The have never come to actually know God. I know a lot of people like that. The have religion and may even be very conservative but something is still missing from their lives. They don't have the spark of fire that comes from having encountered the risen Christ.
Much of my posting on FR is from the desire to probe people and encourage them to ask themselves if they really do know God. (Added to that is a good measure of my own nonsense and ignorance).
