Dear brother Ntinos,
I can't speak for everyone but I can certainly try to answer your questions from all I've read and experienced in my Church:
1) What are the views of Oriental Orthodoxy on Eastern Orthodoxy?
reply: We love and respect the Eastern Orthodox as our Orthodox brethren. We believe that despite what has happened in the past, their Church's Christology is Orthodox, although we have never agreed to use their terminology.
2)Do you recognise the Eastern Orthodox Church as an orthodox Church, and do you believe one can be saved by following the Eastern Orthodox dogma?
reply: Yes. Yes.
3) What are the views of Oriental Orthodoxy on the Roman Catholic Church?
reply: Like we do about our brother Orthodox, we believe the Latin Church is also descended from the Apostles and a true Church of Jesus Christ. Our biggest discrepency with them is their teaching on the Papacy. Historically, we have seen the role of the Roman Papacy in a canonical perspective rather than one that is a matter of revealed faith. Hence our difficulties.
If you are interested in more info along these lines, a couple of suggestions I could make are the following:
On background between the Chalcedonian and Non Chalcedonian Churches:http://www.geocities.com/derghazar/chalcedon.html
On our understanding of Primacy see: Principles of Primacy in the Orthodox Churchhttp://www.geocities.com/derghazar/tradition.html
Hope this helps.
