Grace and Peace Heavenly Pilgrim,
There are a few Church Fathers (Athanasius, Cappadocian Fathers, Maximos the Confessor, etc) who allowed Neo-Platonism to play far too much of a role in interpreting the Scriptures. The Theory that Man was 'created' mortal and that his immortality 'emmanates' from God is part and parcel with the teachings of Neo-Platonism which heavily enfluenced the Alexandrian School (Clement, Origen and others). You will not find it accepted within the Councils nor will you find it in Christianity outside those enfluenced by the Alexandrian School. I know in our modern day such mystical treatises are very intriguing but where they force one to contradict the normative interpretation of Sacred Scripture we 'must' cease to consider them as nourishing for our journey to Calvary.
As I've stated before in another thread, the Doctrine of Original Sin has been Dogmatized by the Councils (both at the regional synod level and also by two Ecumenical Councils.
Council of Mileum II 416, Approved by Innocent and Council of Carthage (XVI) 418, Approved by Zosimus against the Pelagians
The First Canon States:
All the bishops established in the sacred synod of the Carthaginian Chruch have decided that whoever says that Adam, the first man, was made mortal, so that, whether he sinned or whether he did not sin, he would die in body, that is he would go out of the body not because of the merit of sin but by reason of the necessity of nature, let him be anothema.
The Second Canon states:
Likewise it has been decided that whoever says that infants fresh from their mothers' wombs ought not to be baptized, or says that they are indeed baptized unto the remission of sins, but that they draw nothing of the original sin from Adam, which is expiated in the bath of regeneration, whence it follows that in regard to them the form of baptism "unto the remission of sins" is understood as not true, but as false, let him be anathema. Since what the Apostle says: "Though one man sin entered into the world (and through sin death), and so passed into all men, in whom all have sinned" [cf. Romans 5:12], must not to be understood otherwise than as the Catholic Church spread everywhere has always understood it. For on account of this rule of faith even infants, who in themselves thus far have not been able to commit any sin, are therefore truly baptized unto the remission of sins, so that that which they have contracted from generation may be cleansed in them by regeneration.
These Carthaginian canons were accepted by the Church at the Ecumenical Council in AD 431. They were received yet again at the Seventh Ecumenical Council (the Second Council of Nicea) in AD 787. These Canons were and 'must not to be understood otherwise than as the catholic and apostalic Church spread everywhere has always understood it.'
Teachings of Theologians:
Nor does this 'Innovation' resemble the works of Simeon the New Theologian (i.e. The First-Created Man, Seven Homilies) who clearly presents the 'orthodox' teaching of "Original Sin"...
In the present life no one has the divine power in himself to manifest a brilliant glory, and there is no one who is clothed with glory before humility and disgrace; but every man who is born in this world is born inglorious and insignificant, and only later, little by little, advances and becomes glorious.
Therefore, if anyone, having experienced beforehand such disgrace and insignificance, shall then become proud, is he not senseless and blind? That saying that calls no one sinless except God, even though he has lived only one day on earth, does not refer to those who sin personally, because how can a one-day old child sin? But in this expressed that mystery of our Faith, that human nature is sinful from its very conception. God did not create man sinful, but pure and holy. But since the first-created Adam lost this garment of sanctity, not from any other sin but from pride alone, and became corruptible and mortal, all people also who come from the seed of Adam are participants of the ancestral sin from their very conception and birth. He who has been born in this way, even though he has not yet performed any sin, is already sinful through this ancestral sin. - The First-Created Man: Homily 37 The Ancestral (Original) Sin and Our Regeneration by St. Symeon The New Theologian
I can appreciate the Coppadocian Fathers just as much as the next guy but I have to admit that they have opted to contradict the normative interpretation of Scripture for Hellenist Philosophies (Neo-Platonism) which have distorted their teachings.
The modern Orthodox Church is so bent to distinguish itself from Catholicism that it has allow that desire to allow them to stray from what Tradition and Scripture has historically taught due in large part by an over emphasis of a few Church Fathers whom appear to have been overly enfluenced by Polintus and others from the Alexandranian School.
