This world and the world to come are two enemies. We cannot therefore be friends to both; but we must decide which we will forsake and which we will enjoy.
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.'
Pope Clement IWe 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.
