There is more joy in heaven over a converted sinner than over a righteous person standing firm. A leader in battle has more love for a soldier who returns after fleeing, and who valiantly pursues the enemy, than for one who never turned back, but who never acted valiantly either. A farmer has greater love for land which bears fruitfully, after he has cleared it of thorns, than for land which never had thorns but which never yielded a fruitful harvest.
Pope Gregory IThe pastor should always be pure in thought ... no impurity ought to pollute him who has undertaken the office of wiping away the stains in the hearts of others ... for the hand that would cleanse from dirt must be clean, lest, being itself sordid with clinging mire, it soil whatever it touches all the more.
Pope Gregory INow if the wearing of fine and precious robes were not a fault, word of God would never have so carefully expressed this. For no one seeks costly garments except for vainglory, that he may seem more honorable than others; for no one wishes to be clothed with such, where he cannot be seen by others.
Pope Gregory IIf the intention is unclean, the deed that follows from it will also be evil, even if it seems good.
Pope Gregory II despise the proper constructions and cases, because I think it very unfitting that the words of the celestial oracle should be restricted by the rules of Donatus [a well-known grammarian].
Pope Gregory IThe only true riches are those that make us rich in virtue. Therefore, if you want to be rich, beloved, love true riches. If you aspire to the heights of real honor, strive to reach the kingdom of Heaven. If you value rank and renown, hasten to be enrolled in the heavenly court of the Angels.
Pope Gregory I
