"We believe a man to be not simply justified through faith alone, but through faith which works through love, that is to say, through faith and works. But [the idea] that faith can fulfill the function of a hand that lays hold on the righteousness which is in Christ, and can then apply it unto us for salvation, we know to be far from all Orthodoxy. For faith so understood would be possible in all, and so none could miss salvation, which is obviously false. But on the contrary, we rather believe that it is not the correlative of faith, but the faith which is in us, justifies through works, with Christ."
The "correlative of faith" looks to be Christ's righteousness in this statement. In otherwords, its not Christ righteousness alone that saves. Rather its one's faith and works with Christ.
The typical Pop Apologetics of Faith + Works against Roman Catholics, actually looks to be fair for Eastern Orthodox. I thought this was interesting to share.
