Anselmian Substitutionary Atonement in the Church of the East?
"Jesus Christ walked in the flesh thirty-three years on the earth, O King. In the thirtieth year he repaid to God all the debt that the human kind and angels owed to Him. It was a debt that no man and no angel was able to pay, because there has never been a created being that was free from sin, except the Man with whom God clothed Himself and became one with Him in a wonderful unity." - Catholicos Timothy I, Patriarch of the Church of the East (here)
