I just concluded a three week email correspondence with a Catholic Priest about the unity issue. I had seen him on EWTN take cheap shot at the Orthodox. So I wrote to him and we went over the issues. It was fun and informative. However, I have to say that if his attitudes is at all representative of the RCC..there is no shot at unity for a long while.
He is a bit unusual since he is a converted Anglican Priest whom Rome allows to be married. But basically he wants us to come to heel. The air of superiority that he took was not a pretty site. Add to that his basic misconceptions about the Orthodox ( though he had clearly made a study of us) and his unquestioning adherence to Roman dogma hit the trifecta.. "Arrogant, Ignorant and Proud"
And this guy is an author and lecturer and professional apologist, his specialty is with the Evangelicals. He said we and the Evangelicals are both "primitives"..........anyway I wont bore you with more details but the unity thing is a long long long way off IMHO
