The 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 IWhatsoever one would understand what he hears must hasten to put into practice what he has heard.
Pope Gregory IAct in such a way that your humility may not be weakness, nor your authority be severity. Justice must be accompanied by humility, that humility may render justice lovable.
Pope Gregory I
