"Then peaceable." Important as peace is, purity is paramount. Peaceableness is, to be sure, the outer characteristic of wisdom, and if one has the bright light of inner wisdom, he will have it. But wisdom does not desire peace at any price or at the cost of purity. "All her paths are peace" (Prov. 3:17), and the chastening of God's hand yields "peaceable fruit unto them that have been exercised thereby" (Heb. 12:11). Plummer wisely notes that the order of James here is logical and not always strictly chronological.
One is not to compromise with evil and error, but all the same, if one is to have no peace till he has absolute purity of every sort in his environment, he must needs be always at war and never rest at all. An equation of common sense must, of course, be struck, though there is the constant temptation to get used to unpleasant surroundings and finally to make no protest at all. Plummer likewise observes that James places the emphasis on the spiritual and moral, not on the intellectual, just the opposite of modern ideals of culture and education. There is nothing in the position of James to justify the Spanish Inquisition, for instance. The persecutor has often consoled himself with the thought that he is doing his victim's soul a real service by rescuing him from his error.
Certainly, if one is pure, it is easier for him to be peaceable, provided he also loves. "If it be possible, as much as in you lieth, be at peace with all men" (Rom. 12:18). There is a great deal in the New Testament on the subject of peace. It is true that Jesus said, "I came not to bring peace, but a sword" (Matt. 10:34), when men are wedded to sin and can only be shaken loose by the sword of truth. But there are those who let the peace of God rule in their hearts as umpire (Col. 3:15). We are to pursue the things of peace (Rom. 14:19) as men of peace but not to be afraid to stand up for truth and righteousness (purity), even if we have to fight.
Then "gentle," "forbearing" (Hort). The word is used by Thucydides (viii. 93) of men who will listen to reason, and (i. 76) of moderation, like the Latin _clementia_. Originally the word meant what was fitting, fair, reasonable, but it was also associated with the idea of yielding, "implying one who does not stand on his rights, but is ready to give way to the wishes of others" (Mayor). Matthew Arnold gathered the idea into his phrase "sweet reasonableness." Aristotle (vi. 11) uses it of the forgiving man, one who does not stand on strict justice but who listens to merciful consideration. Certainly gentleness is the true mark of the gentleman who does not stickle over little points, who, in a word, is considerate.
