It is a baseless assumption to suppose that the rich man here spoken of is a Christian at all. "The brother of low degree" is contrasted, not with the _brother_ who is rich, but with the rich man, whose miserable destiny shows that he is not "a brother," _i.e._ not a believer. The latter is the wealthy Jew who rejects Christ. Throughout this Epistle (ii. 6, 7; v. 1-6) "rich" is a term of reproach. This is what is meant by the Ebionite tone of the Epistle; for poverty is the condition which Ebionism delights to honour. In this St. James seems to be reproducing the thoughts both of Jesus Christ and of Jesus the son of Sirach. "Woe unto you that are rich! for ye have received your consolation. Woe unto you, ye that are full now! for ye shall hunger" (Luke vi. 25, 26. Comp. Matt. xix. 23-25). "The rich man hath done wrong, and is very wroth besides: the poor man is wronged, and he must intreat also.... An abomination to the proud is lowliness; so the poor are abomination to the rich" (Ecclus. xiii. 3, 20).
But when we have arrived at the conclusion that the "being made low" does not refer to the humiliation of the Christian, and that the rich man here threatened with a miserable end is not a believer, a new difficulty arises. What is the meaning of the wealthy unbeliever being told to _glory_ in the degradation which is to prove so calamitous to him? In order to avoid this difficulty various expedients have been suggested. Some propose a rather violent change of _mood_--from the imperative to the indicative. No verb is expressed, and it is said that instead of repeating "let him glory" from the previous clause, we may supply "he glories," as a statement of fact rather than an exhortation. The sentence will then run, "But let the brother of low degree glory in his high estate; but (δέ) the rich _glorieth_ in his being made low;" _i.e._ he glories in what degrades him and ought to inspire him with shame and grief. Others propose a still more violent change, viz. of _verb_; they would keep the imperative, but supply a word of opposite meaning: "so let the rich man _be ashamed_ of his being made low." Neither of these expedients seems to be necessary, or indeed to be a fair treatment of the text.[44] It is quite possible to make good sense of the exhortation, without any violent change either of mood or of verb. In the exhortation to the rich man St. James speaks in severe irony: "Let the brother of low degree glory in his high estate; and the rich man--what is he to glory in?--let him glory in the only thing upon which he can count with certainty, viz. his being brought low; because as the flower of the grass he shall pass away." Such irony is not uncommon in Scripture. Our blessed Lord Himself makes use of it sometimes, as when He says of the hypocrites that they have their reward, and have it in full (ἀπέχουσι: Matt. vi. 2, 5, 16).
Whether or no this interpretation be accepted--and no interpretation of this passage has as yet been suggested which is free from difficulty--it must be clearly borne in mind that no explanation can be correct which does not preserve the connexion between the humiliation of the rich man and his passing away as the flower of the grass. This fading away _is_ his humiliation, _is_ the thing in which he is to glory, if he glories in anything at all. The inexorable "because" must not be ignored or explained away by making the wealth of the rich man shrivel up, when St. James twice over says that it is the rich man himself who fades away.
The metaphor here used of the rich man is common enough in the Old Testament. Man "cometh forth like a flower, and is cut down" (ὥσπερ ἄνθος ἀνθῆσαν ἐξέπεσεν LXX.), says Job, in his complaint (xiv. 2); and, "As for man, his days are as grass; as a flower of the field, so he flourisheth. For the wind passeth over it, and it is gone; and the place thereof shall know it no more," says the Psalmist (ciii. 15, 16). But elsewhere, with a closer similarity to the present passage, we have this transitory character specially attributed to the ungodly, who "shall soon be cut down like the grass, and wither as the green herb" (Ps. xxxvii. 2). None of these passages, however, are so clearly in St. James's mind as the words of Isaiah: "All flesh is grass, and all the goodliness thereof is as the flower of the field: the grass withereth, the flower fadeth; because the breath of the Lord bloweth upon it: surely the people is grass. The grass withereth, the flower fadeth; but the word of our God shall stand for ever" (Isa. xl. 6, 7). Here the words of St. James are almost identical with those of the Septuagint (ὡς ἄνθος χόρτου· ἐξηράνθη ὁ χόρτος καὶ τὸ ἄνθος ἐξέπεσεν ... ἐξηράνθη χόρτος, ἐξέπεσεν τὸ ἄνθος); and, as has been already pointed out (p. 59), this is one of the quotations which our Epistle has in common with that of St. Peter (1 Peter i. 24).
