That is one topic that I know for certain that Father Ambrose can address far better than I can do it. It is a particularly sensitive one for him too, and he is always challenging other Orthodox clergy...and sadly he seems to loose the battle more often than not. But I will let him address that.
Topics that don't co-inside precisely include the presence of an eternal priesthood, the real presence in Eucharist, varying teachings on the atonement and salvation, varying perspectives on the ancestral sin....
I said that there is no monolithic or universal teaching in Orthodoxy that brooks NO deviance one jurisdiction from another.
These are your words, Mary. I'm sure the rest of us are particularly interested in deviations within the Orthodox world in the teaching of the Real Presence.
In the year 2004 there was a heavy debate sparked on the Yahoo group Orthodox-Forum by some unlearned clergy who denied that the soul and divinity of Christ are present in the Holy Gifts. They based this claim on Scripture where Christ says "This is My body" and This is My blood" and he does not mention his soul and divinity.
To deny that soul and divinity are also in the Holy Gifts is a radical assault on the teaching of Chalcedon concerning the Hypostatic Union, the God-Man, etc.
This heretical position was being espoused by one silver-tongued monk from the OCA and one rather sorry priest. Mary likes to make out that there was truckload of clergy supporting the heresy but it was only two contributors to Orthodox-Forum.
So Mary and I formed an alliance in defence of the Hypostatic Union and sent many messages to the Orthodox-Forum to prove the point, with citations from Saint John of Damascus, Irenaeus of Lyons, Symeon the New Theologian, Fr Michael Pomazansky, various Greek theologians, etc.
These messages can still be accessed on Orthodox-Forum. Do a search using emrys
for the Name of the Author and using body blood soul divinity
for the Subject Line. But last time I looked the overtly heretical ones did not seem to be there any more.
Months later I was surprised to receive a message from America from a bishop saying that the Orthodox-Forum debate had been brought to his attention and he had taken some measures to apprise the erring clergy of the Church's teaching.
