So in Orthodoxy a Baptised person is not truly saved until they are Chrismated.
So in Orthodoxy a person is never fully saved because of the infinite depth of God.
I think you are confusing salvation and theosis.
Yes, salvation is part of theosis.
Can you explain (maybe in another thread) the problem which the Oriental Church has with theosis. This matter is apparently at the base of the decades long feud between Pope Shenouda (and other Oriental hierarchs) and Fr Matta the Poor.
This touches on a topic I was just about to post about in this thread, that was originally going to be in response to some of the things you have said:
"I know that you are heading into the Oriental Church and you may want to look at the teaching of Pope Shenouda and also Mar Bishoy (the second-ranking bishop of the Coptic Church)"
"I am disinclined to try. He has rejected Eastern Orthodoxy which strongly implies that he has found answers from Orthodox priests of the East quite unsatisfactory, certainly not satisfactory nor convincing enough to keep him in the E Orthodox Church. It would be more compelling for him if an Oriental priest were to answer his question."
"I regret that no Oriental Orthodox have as yet taken up your question and made an answer, so I shall offer one thing for contemplation..."
"But as I wrote earlier, I believe you should seek understanding on this question from an Oriental priest and I imagine that you are already under instruction as you make the journey into the Oriental Church."
"The point I am making is that there are some unexpected surprises in Oriental baptismal theology as well as contrary teachings among the Oriental Churches. This makes it presumptuous for Roman Catholics and Eastern Orthodox to answer your question. Discuss it with the Oriental priest who is catechising you. And if you like to get back to us with his answers, I for one would be interested."
I think you overestimate how staunchly attached to Oriental thinking I am. I have a strong respect for my Byzantine patrimony. The only issue where I have fundamentally rejected the teachings of your church is certain teachings from the Council of Chalcedon. Almost everything else that your church teaches I find orthodox and satisfying teaching (even when it uses different Christological terminology; through I prefer to use Oriental terminologies in the matter of Christology). There is a great deal in your tradition which is essentially not really found in the Oriental tradition that I uphold. For one thing, iconodulism to the extent that is found in the Byzantine tradition is not really found in the Oriental churches, except perhaps close in the African OO churches. On this issue, I am essentially almost if not as affirming of inconodulia as an EO. Another thing is the Palamite Theology. I am also very affirming of Palamite particulars, including the Essence-Energies distinction.
So, when you ask about theosis, I can't really answer your question. This is another topic in which I find myself siding with the teachings of your church. What I was expressing before was not hypothetical, but rather an expression of my own beliefs.
Finally, no I am in a finalized catechetical relationship with any one Priest/Bishop. You probably haven't seen it, but I've been having a fair amount of debate with other OO about the Agreed Statements. In the Agreed Statements it is said that both parties have "always loyally maintained the same authentic orthodox christological faith". The implication of this statement is that you did so even at the Council of Chalcedon, which does not leave room for your tradition having been heterodox in and with the council or even having had compromised pure orthodoxy with some heterodox at the council. That pure orthodoxy was compromised at Chalcedon I am convinced of, and I am also convinced that this is the Traditional OO teaching. So, I essentially see the Agreed Statements as likewise compromising that Tradition. Whether I can even be in Communion with those who accept, thus, is questionable. This is primarily why I have not pushed forward more in the inquiring process, as I feel I need to have that issue ironed out before I do, so I can even be sure where exactly to enter into my catechesis.
