Dear G4m,
In fact, there's no need to be confused.
The quote below, taken from Bp. Alexander's article
is in complete agreement with Orthodox theology. I double-checked with two priests when I translated it to Portuguese.
And while it does use some terminology that is not "standard," such as "guilt" - in general it is a collection of paraphrases from Scripture itself. And the final sentence is purely Orthodox - we do not attempt to explain why such a horrible sacrifice was required.
As a side note, I'd like to point out that while Anselm's theology takes a different perspective from that of the eastern Church Fathers, in general his works are certainly not heretical (i.e., they do not teach a wrong doctrine).
I guess this is just a matter of different, but not necessarily conflicting, point of views (Western Medieval x Eastern Orthodox).
Hope this helps.
Yours in XC,
Rick
