28 Guard your soul safely, lest at any time thou eat of things offered to idols: for concerning meats of this kind, not only I at this time, but ere now Apostles also, and James the bishop of this Church, have had earnest care: and the Apostles and Elders write a Catholic epistle to all the Gentiles, that they should abstain first from things offered to idols, and then from blood also and from things strangled. For many men being of savage nature, and living like dogs, both lap up blood, in imitation of the manner of the fiercest beasts, and greedily devour things strangled. But do thou, the servant of Christ, in eating observe to eat with reverence. And so enough concerning meats.
Of Apparel.
