That’s not what they say.
From Wikipedia on
Eastern Orthodox Christian theology:
In Eastern Orthodoxy, God created man perfect with free will and gave man a direction to follow. Man (Adam) and Woman (Eve) chose rather to disobey God by eating from the Tree of Knowledge of Good and Evil, thus changing the “perfect” mode of existence of Man to the flawed or “fallen” mode of existence of Man. This fallen nature and all that has come from it is a result of “original sin.” All humanity participates in the sin of Adam because like him, they are human and follow in his ways. The union of humanity with divinity in Jesus Christ restored, in the Person of Christ, the mode of existence of humanity, so that those who are incorporated in him may participate in this renewal of the perfect mode of existence, be saved from sin and death, and be united to God in deification. Original sin is cleansed in humans through baptism or, in the case of the Theotokos, the moment Christ took form within her.
This view differs from the Roman Catholic doctrine of original sin, the legacy of Latin father Augustine of Hippo, in that Man is not seen as inherently guilty of the sin committed by Adam, conceived as the federal head and legal representative of the human race.[7] According to the Orthodox, humanity inherited the consequences of that sin, not the guilt. The difference stems from Augustine’s interpretation of a Latin translation of Romans 5:12 to mean that through Adam all men sinned, whereas the Orthodox reading in Greek interpret it as meaning that all of humanity sins as part of the inheritance of flawed nature from Adam. The Orthodox Church does not teach that all are born guilty and deserving of damnation, and Protestant doctrines such as predestination which are derived from the Augustinian theory of original sin and are especially prominent in the Lutheran and Calvinist traditions, are not a part of Orthodox belief.
Note that the article seems to me to misrepresent Catholic teaching on original sin. They know their beliefs, but do not know that they parallel Catholic teaching quite closely.
From the
Orthodox wiki on Original sin we see a similar thing:
The term Original Sin (or first sin) is used among all Christian churches to define the doctrine surrounding Romans 5:12-21 and 1 Corinthians 15:22, in which Adam is identified as the man whom through death came into the world. How this is interpreted is believed by many Orthodox to be a fundamental difference between the Eastern Orthodox Church and the Western Churches. In contrast, modern Roman Catholic theologians would claim that the basic anthropology is actually almost identical, and that the difference is only in the explanation of what happened in the Fall. In the Orthodox Church the term ancestral sin (Gr. προπατορικό αμάρτημα) is preferred and is used to define the doctrine of man’s “inclination towards sin, a heritage from the sin of our progenitors” and that this is removed through baptism. St. Gregory Palamas taught that man’s image was tarnished, disfigured, as a consequence of Adam’s disobedience.
Again, the teaching is semantically different, but it’s a distinction without (much of) a difference.
So, I strongly concur with PRmerger’s assessment.
Hmmm … did you read the part quoted above which said: " Original sin is cleansed in humans through baptism or, in the case of the Theotokos, the moment Christ took from within her."?
Apparently not.
