8 You complain that the fountains are now less plentiful to you, and the breezes less salubrious, and the frequent showers and the fertile earth afford you less ready assistance; that the elements no longer subserve your uses and your pleasures as of old. But do you serve God, by whom all things are ordained to your service; do you wait upon Him by whose good pleasure all things wait upon you? From your slave you yourself require service; and though a man, you compel your fellow-man to submit, and to be obedient to you; and although you share the same lot in respect of being born, the same condition in respect of dying; although you have like bodily substance and a common order of souls, and although you come into this world of ours and depart from it after a time with equal rights, and by the same law; yet, unless you are served by him according to your pleasure, unless you are obeyed by him in conformity to your will, you, as an imperious and excessive exactor of his service, flog and scourge him: you afflict and torture him with hunger, with thirst and nakedness, and even frequently with the sword and with imprisonment. And, wretch that you are, do you not acknowledge the Lord your God while you yourself are thus exercising lordship?
