We made bad use of immortality, and so ended up dying; Christ made good use of mortality, so that we might end up living.
Saint AugustineYour first task is to be dissatisfied with yourself, fight sin, and transform yourself into something better. Your second task is to put up with the trials and temptations of this world that will be brought on by the change in your life and to persevere to the very end in the midst of these things.
Saint AugustineIn the Catholic Church, there are many other things which most justly keep me in her bosom. The consent of peoples and nations keeps me in the Church; so does her authority, inaugurated by miracles, nourished by hope, enlarged by love, established by age. The succession of priests keeps me, beginning from the very seat of the Apostle Peter, to whom the Lord, after His resurrection, gave it in charge to feed His sheep (Jn 21:15-19), down to the present episcopate.
