“For God is just, and therefore he could not justify the unjust. Therefore he required the intervention of a propitiator, so that by having faith in Him those who could not be justified by their own works might be justified.”
“A man is justified by faith. The works of the law can make no contribution to this. Where there is no faith which might justify the believer, even if there are works of the law these are not based on the foundation of faith. Even if they are good in themselves they cannot justify the one who does them, because faith is lacking, and faith is the mark of those who are justified by God.”
– Origen (185-254), Commentary on Romans, 2.112; 2.136
