"Fastings, vigils, meditations on the Scriptures, self-denial, and the abnegation of all possessions are not perfection in themselves, but aids to perfection. The end of the science of holiness does not lie in these practices, but by means of them we arrive at the end. He will practice these exercises to no purpose who is contented with these as if they were the highest good. A man must not fix his heart simply on these, but must extend his efforts towards the attainment of his end. It is for the sake of the end that these things should be cultivated. It is a vain thing for a man to possess the implements of an art and to be ignorant of its purpose, for in it is all that is of any value." Abba Moses
Or to put it in other, more authoritative words, "I have desired mercy rather than sacrifice." Prayer and scripture and all other disciplines and religious actions are worthwhile only insomuch as they lead on to love for our neighbors and, above all, love for God.
