Saint AugustineIf there is something more excellent than the truth, then that is God; if not, then truth itself is God.
Saint AugustineLove all men, even your enemies; love them, not because they are your brothers, but that they may become your brothers. Thus you will ever burn with fraternal love, both for him who is already your brother and for your enemy, that he may by loving become your brother.
