We should let God be the One to praise us and not praise ourselves. For God detests those who commend themselves. Let others applaud our good deeds.
Pope Clement IAnd we, too, being called by His will in Christ Jesus, are not justified by ourselves, nor by our own wisdom, or understanding, or godliness, or works which we have wrought in holiness of heart; but by that faith through which, from the beginning, Almighty God has justified all men; to whom be glory for ever and ever. Amen.
Pope Clement ILet us cleave... to those who cultivate peace with godliness, and not to those who hypocritically profess to desire it. For the Scripture says in a certain place (Mk. 7:6), 'This people honors Me with their lips, but their hearts is far from Me.'
