Dearest to Christ Lellimore,
Origen was excommunicated by his own Bishop (as Stavro related) but not for heresy. He was excommunicated for two reasons: 1) self-mutilation 2) illegal ordination. Later his memory has been profaned by influential figures such as Sts. Methodios and Epiphanios.
Emperor Justinian sought to have Origen condemned due to his struggles with "origenist" monks in his Empire. There were several versions of "origenism" at that time and none of them are loyal to Origen himself, his name is simply used as a final authority. Origen's name carried great authority for a while,.. and this is whay heretics have always attempted to claim his authority, and sadly, some have succeeded in attaching his name to heresies he had no part of whatsoever (of which the teaching of reincarnation was one, the doctrine of successive worlds was one, and the idea of spherical bodies another one, etc).
Origen's theology suffers from common pre-Nicene deficiencies;
1) a kind of subordinationism (yet acknowledging the consubstantiality) in his trinitarianism
2) a onesided identification of Wisdom and Logos (leading to a conflicting theology of creation and again subordinationism)
3) an insufficient clarity concerning original sin and "the doctrine of man" (anthropology), including what is generally (but erroneously) called the pre-existence of the soul
4) and to an almost unique degree for Origen, his theology suffers from misquotation by heretics and his "guilt by this association"
I have a personal interrest in Origen, cos he has been the one God used to save me from the Protestant-Evaneglical fundamentalism, that was destroying my very soul and spirit. When I found out about his "condemnation" I started a long lasting search about the issue, and to my joy found out that Origen can be cleared of heresy, tho not of all weaknessess in his theology. But as for many in his own time, Origen is a father to me in Orthodoxy, and I am grateful to him.
