Ugh more cant about how the Orthodox do not believe that Christ atoned for our sins on the Cross. Let me just submit two quotations from the Fathers:
“Since the Lord offered Himself up for us in
sacrifice to the Father, having propitiated Him by His death as High Priest
and then, after the destruction of sin and cessation of enmity, sent unto us the
Spirit, He says: ‘I will beseech the Father and will give you a Comforter, that
is, I will propitiate the Father for you and reconcile Him with you, who were
at enmity with Him because of sin, and He, having been propitiated by My
death for you and been reconciled with you, will send you the Spirit.”
This is from Blessed Theophylact, who lived at the same time as the alleged inventor of "atonement theory", Anselm of Canterbury (Explanation of the Gospel of John, 14:16).
And from the great opponent of scholasticism, St Gregory Palamas:
“Man was led into his captivity when he
experienced God’s wrath, this wrath being the good God’s just abandonment
of man. God had to be reconciled with the human race, for otherwise
mankind could not be set free from the servitude. A sacrifice was needed to
reconcile the Father on high with us and to sanctify us, since we had been
soiled by fellowship with the evil one. There had to be a sacrifice which both
cleansed and was clean, and a purified, sinless priest…. God overturned the
devil through suffering and His Flesh which He offered as a sacrifice to God
the Father, as a pure and altogether holy victim – how great is His gift! – and
reconciled God to the human race…” (Homily 16:21, 24, 31)
