Thank you. I will look into your comments in that subforum.
Do OO view grace as theosis. In that it happens during our life. Or is it a reward on judgement day?
Theosis is the union of man with God through the grace of our Lord, God, and Savior, Jesus Christ, Who by His life, death, and glorious resurrection has established for us the only true way to salvation. It happens in our lives when we approach the holy mysteries in liturgy with all humility in prostration before them and take within us His holy and precious body and blood, which are given for the salvation of all who believe in Him and confess His death, resurrection, and second coming together with us, but also when we pray at the seven appointed times throughout the day in the Agpeya or extemporaneously at any time, and when we fast the holy eight fasts of the Coptic year and celebrate the feasts together with the Church, or do any other thing as appointed and encouraged by the Church and her holy fathers beginning from our masters the apostles and disciples and down to this very day. As God is eternal, and God-willing we will live with Him eternally in heaven, this process has no end, and there is no true separation between death and life such that it can be a "reward" on judgment day, because He will be the same on that day and after it, and He has promised His faithful that as He lives they too shall live.
Please focus here on the comments of HG Bishop Moussa (the man giving the talk after the prayers), from the funeral of the martyrs of the New Years' Day bombing of the Church of the Saints in 2011. They say it much better than I could, even as HG does not use the specific word "Theosis" (in Arabic,
ta'alah, which apparently has a lot of theological baggage attached to it, as explained by
a native Arabic-speaking Coptic person on OC.net here; the whole thread is worth a read, really, if you want to get into the technical side of all of this; as a person who only learned the basics of the language as a fourth language, with only working knowledge of "Church Arabic" from the liturgy, I cannot evaluate this on the level that they do in that thread):
I should note here for the sake of balance that some modern Coptic writers and priests (prominent among them is Fr. Athanasius Iskander, who is not a lightweight in Coptic circles, as far as I understand)
have advocated that other terms would be better suited to express the Coptic Orthodox position vis-a-vis Theosis. Fr. Athanasius argues in one of his writings for the term
theopoiesis, but as the particular writing I have in mind is
extremely polemical in ways that I cannot myself stand behind (not because I assume Fr. Athanasius is wrong, but because I don't know about a lot of the things he brings up, and besides I am obliged to follow my bishop's teaching, which is obviously in favor of the term
theosis), I will not present it here. I only mention it so that any reader can know that such points of view are out there, though I couldn't tell you how popular they are. I have no interest in arguing against EO just for the sake of it if I can't even understand why I should be doing that, so please don't take this mention as any kind of personal endorsement of the view that
theosis is incorrect. I think Fr. Athanasius' extreme boldness in this matter has to do with the way that some of the statements of St. Gregory Nazianzen (who is a saint in our Church and wider communion) have been taken by later EO theologians and writers, but again, I don't know anything about that. And also, with respect due to the good father, it seems that Fr. Athanasius might be misreading some of the Cappadocian fathers, as when he claims that they have said that virtues such a virginity can in themselves deify man; I don't recall ever reading that in either St. Gregory Nazianzen or St. Gregory of Nyssa, who Fr. Athanasius claims this about...perhaps I missed it, or perhaps I am not understanding the basis for his claim.
If I may venture to do a bit of personal wondering on this last point (Lord have mercy), I think one area that might be worth exploring is what I have sensed to be a bit of a distinction in how OO (or at least Copts; I don't intend to speak for all of the OO, as I don't know everyone else's prayers) and EO talk about Christ's incarnation with regard to His taking on the flesh. This is maybe not so directly related to your question, OP, but is certainly in that same area, so hopefully this diversion will not be a waste of everyone's time (again, Lord have mercy).
I have posted before in a thread in which you participated on what I considered to be a very interesting and confusing change in wording in an episode of the popular
Orthodoxy and Heterodoxy podcast on AFR, hosted by Fr. Andrew Stephen Damick (I don't know if EO are like us and refer to their priests by their first name, or if he would be called Fr. Damick), who is of the Antiochian EO Church. As you can read at the link, the change was such that any talk of Christ's human nature being subject to the fall has been excised (I still have the original on my ipod, though, so that's how I know it has changed), and it seems the consensus among the EO -- at least in that thread -- is that the humanity that was assumed by Christ was in its 'pre-lapsarian' state, i.e., before the fall of Adam and Eve.
I am not 100% sure (in fact, I'm zero percent sure, because this is
another thing where I cannot find writings from OO on this particular bit of theological philosophy, or whatever you'd call it; there seem to be
a lot of subjects where we just don't have readily accessible writings to look at, because we seemingly didn't develop this question or an answer to it in the first place, as you guys did; in a way it kind of stinks, but I guess it's also a testimony to how we really have kept to only the first three councils, in terms of what we have defined and what we have not), but I
think we would say instead that it was in the assuming of the flesh, i.e., at/with/through
the incarnation itself that the flesh was redeemed/made holy/elevated or however you'd like to put it (in other words, it was not 'pre-lapsarian', as He took flesh from the Virgin Theotokos St. Mary, and her flesh was not 'pre-lapsarian', i.e., she was subject to the fall, while He was not because He redeemed the flesh
by assuming it, and hence went through a voluntary death for us sinners).
Coptic Orthodox Christology is
heavily 'incarnational', and it is basically impossible to understand without understanding this as the basis of it. On the other hand, when/if it does 'click' with you, it opens up an entire world of theology that really puts you back in the days of our fathers...yes, I
am plugging my own communion here, as is perfectly right to do, but without denigrating what others may believe I am also trying to show a bit of what being OO looks like "from the inside", where instead of having these questions on grace and the exact nature of Christ's flesh or whatever, we have what we proclaim in our liturgies and prayers and vigils, and what has established Christian monasticism which is doubtlessly the greatest gift of the Church in Egypt to the world, and so on. It is 'simpler', perhaps, but just as still waters run deep, within that simplicity and I guess ignorance of what others are doing or have done there is the unshakable belief that Christ came in the form of a servant, and blessed our nature in Himself, and by truly uniting His divinity and His humanity and making it
one, He has prepared for us the way to salvation and theosis that is accomplished eternally through His defeat of death upon the holy wood of the life-giving cross. I'm not going to say you can't get there with this 'pre-lapsarian' belief or with Chalcedonianism more generally, because that's not my call to make and I don't intend to make this thread about Chacledon -- by God, I am sick of even typing or thinking that name -- but I will say that this is what I understand to be the basis of our Orthodox faith, and this is how we believe it and always have and always will. And as our good friend and sister in Christ Anastasia has put it, I am grateful for that assurance.
