We have seen that Ecumenical Councils HAVE touched upon the same issues that are at the heart of the creation/evolution debate.
The 6th and 7th Councils ratified a canon from Carthage that says:
//That whosoever says that Adam, the first man, was created mortal, so that whether he had sinned or not, he would have died in body—that is, he would have gone forth of the body, not because his sin merited this, but by natural necessity, let him be anathema.//
it's rather obvious how this contradicts evolution. we've seen in this thread already people who deny that man was created NOT mortal.
further, Trullo also teaches us how to proceed when there is a controversy, as there is now:
//It behooves those who preside over the
churches, every day but especially on Lord's days, to teach all the
clergy and people words of
piety and of right religion, gathering out of
holy Scripture meditations and determinations of the
truth,
and not going beyond the limits now fixed, nor varying from the tradition of the God-bearing fathers. And if any controversy in regard to Scripture shall have been raised, let them not interpret it otherwise than as the lights and doctors of the church in their writings have expounded it, and in those let them
glory rather than in composing things out of their own heads, lest through their lack of skill they may have departed from what was fitting.//
note that we follow the tradition of the fathers because they are GOD-BEARING. the Church does not doubt, belittle, or downplay their experiences of God.
so we see, the continual claim that the Church has not spoken on the matter is quite flimsy when you consider that for 2,000 years the Church HAS indeed spoken on what Genesis means. Now we need only apply what has already been said.
Following on this, St. Theophan the Recluse says that Darwin and his followers rightly deserve to be added to the anathemas in the Rite of Orthodoxy,
but there is no need to do so since such teachings have been anathematized already long ago!
so, when a little study is done, we see that grasping at this straw just doesn't work.
