Ummm...Papacy, Filioque, Purgatory, Indulgences, Immaculate Conception are usually the main doctrines that present Coptic heirarchs have voiced complete opposition against. I'm not debating the issues in essence, but just mentioning what doctrines the Coptic Church has beef with. Neither am I going to say if anyone is "lost" or not. That's not the point of this thread, at least I hope.
In addition, I have my personal disagreements with His Eminence as well, which I've expressed elsewhere here.
