I don't mean to stir things but I have heard a number of Orthodox people object to evolution and I honestly don't understand the objection. I don't claim to be any great theologian but what Pensees has said is essentially how I have come to understand and what other Orthodox people have explained to me is the way in which evolution is indeed quite compatible with Orthodoxy.
We Orthodox understand that it is God Who creates but that we do not know how he goes about doing this. Personally, it matters not to me the precise, step-by-step means whereby creation and human life came into being because I have faith that, however God chose to do it, it was God Who did, and does, it.
I love Orthodoxy for its much fuller and better-developed theology of theosis than I found in my past existence - the way in which God, the Creator of all things visible and invisible, draws His creation unto Himself, allowing it to develop and grow in a loving, nurturing relationship with Him, into the fullness of life in Him.
I don't think that it is necessary for us to accept one scientific theory or another of how things came to be as they are today because I just don't see it as being essential to the life of an Orthodx Christian or the life of the Church. However, as far as evolutionary theory goes, I am yet to have anybody explain to me why it is incompatible with Orthodoxy. Don't misunderstand me: I'm not rejecting this statement and would be delighted to hear what people who think that way have to say. It's just that, up until now, those people who have said this to me have never been willing to explain to me the reasons behind their assertion and so I have just been left wondering what they mean.
I attended an Orthodox lecture about this last year and the text has since been refined into essay form, and may be viewed here.
