The 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 IAs long as the vice of gluttony has a hold on a man, all that he has done valiantly is forfeited by him: and as long as the belly is unrestrained, all virtue comes to naught.
Pope Gregory IWhatsoever one would understand what he hears must hasten to put into practice what he has heard.
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
