If we are, in fact, now occupied in good deeds, we should not attribute the strength with which we are doing them to ourselves. We must not count on ourselves, because even if we know what kind of person we are today, we do not know what we will be tomorrow.
Pope Gregory IThe holy universal Church teaches that it is not possible to worship God truly except in Her and asserts that all who are outside of Her will not be saved.
Pope Gregory IThere 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 IObedience is the only virtue that plants the other virtues in the heart and preserves them after they have been planted.
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.
