God allowed His Son to suffer as if a condemned sinner, so that we might be delivered from the penalty of our sins. This is God’s righteousness,
that we are not justified by works (for then they would have to be perfect, which is impossible), but by grace, in which case all our sin is removed.

-from his Homilies on the Epistles of Paul to the Corinthians, composed and delivered sometime in the latter half of the 4th century.
