our septuagint comes to the rescue again!
isaiah 53:10 courtesy of the orthodox study Bible:
'The Lord wishes to cleanse Him of His wound, and if you give an offering for sin, Your soul shall see a long-lived seed'.
i also didn't subscribe completely to substitutionary atonement as a protestant, but that was partly because the groups i hung out with disliked all tradition and theology, including protestant theology!
but now i hang out a lot with a calvinist, so heavy theology is on the menu, and i have decided to read:
'on the incarnation' by saint athanasius (the one with the nicean creed in 451AD), available here:http://www.copticchurch.net/topics/theology/incarnation_st_athanasius.pdf
i will post more if i understand it (don't hold your breath; over 90 pages), and in the mean time would welcome any orthodox summaries of this small book, especially why we don't believe the death and resurrection of Jesus Christ involved the wrath of God the Father being directed to God the Son.
your prayers would also be very welcome!
