XI. (39) But many, who are not able vigorously to refute the plausible inventions of the sophists, because they have not very much practised discussion by reason of their continued application to action, having taken refuge in the alliance of the only wise Being, and have besought him to become their defender. As one of the friends of Moses, when praying, says in his hymns, “Let the treacherous lips become Mute;”{7}{#ps 30:19.} and how can they become mute if they are not curbed by the only being who has speech itself as his subject? (40) We must therefore flee, without ever turning back, from all associations entered into for the purposes of sin; but the alliance made with the companions of wisdom and knowledge must be confirmed. (41) In reference to which I admire those who say, “We are all one man’s sons, we are men of Peace,”{8}{#ge 42:11.} because of their well-adapted agreement; since how, I should say, could you, O excellent men, avoid being grieved at war, and delighted in peace, being the sons of one and the same father, and he not mortal but immortal, the man of God, who being the reason of the everlasting God, is of necessity himself also immortal? (42) For they who make out many beginnings of the origin of the soul, being devoted to the evil which is called polytheism, and turning each individual of them, to the honour of different beings, having caused great confusion and dissension both at home and abroad, from the beginning of their birth to the end of their life, filling life with irreconcilable quarrels; (43) but they who rejoice in one kind alone, and who honour one as their father, namely right reason, admiring the wellarranged and all-musical harmony of the virtues, live a tranquil and peaceful life, not an inactive and ignoble one, as some persons think, but one of great manliness, and sharpened, and vigorous against those who endeavour to break the confederacy which they have formed, and who are always studying to bring about a violation of the oaths which have been taken; for it has come to pass that the men of peace have become men of war, sitting down to attack and to oppose them who seek to overturn the firmness of the soul.
