It remains to examine the relations between our Epistle and the First Epistle of St. Peter. Here, again, one of the coincidences occurs in the passage before us. St. James writes, "Count it all joy, when ye enter into manifold temptations; knowing that the proof of your faith worketh patience;" and St. Peter writes, "Ye greatly rejoice, though now for a little while, if need be, ye have been put to grief in manifold temptations, that the proof of your faith ... might be found" (1 Peter i. 6, 7). Here there is the thought of rejoicing in trials common to both passages, and the expressions for "manifold temptations" and "proof of your patience" are identical in the two places. This is remarkable, especially when taken with other coincidences. On the other hand, the fact that some of the language is common to all three Epistles (James, Peter, and Romans) suggests the possibility that we have here one of the "faithful sayings" of primitive Christianity, rather than one or two writers remembering the writings of a predecessor.
In three places St. James and St. Peter both quote the same passages from the Old Testament. In i. 10, 11 St. James has, "_As the flower of the grass_ he shall pass away. For the sun ariseth with the scorching wind, and _withereth the grass; and the flower_ thereof _falleth_," where the words in italics are from Isaiah xl. 6-8. St. Peter (i. 24) quotes the words of Isaiah much more completely and consecutively, and in their original sense; he does not merely make a free use of portions of them. Again, in iv. 6 St. James quotes from Prov. iii. 34, "God resisteth the proud, but giveth grace to the humble." In v. 5 St. Peter quotes exactly the same words. Lastly, in v. 20 St. James quotes from Prov. x. 12 the expression "covereth sins." In iv. 8 St. Peter quotes a word more of the original, "love covereth sins." And it will be observed that both St. James and St. Peter change "covereth _all_ sins" into "covereth _a multitude_ of sins."
Once more we must be content to give a verdict of "Not proven." There is a certain amount of probability, but nothing that amounts to proof, that one of these writers had seen the other's Epistle. Let us, however, assume that echoes of one Epistle are found in the other; then, whichever letter we put first, we have no chronological difficulty. The probable dates of death are, for St. James A.D. 62, for St. Peter A.D. 64-68. Either Epistle may be placed in the six or seven years immediately preceding A.D. 62, and one of the most recent critics[31] places 1 Peter in the middle of the year A.D. 50, and the Epistle of James any time after that date. But there are good reasons for believing that 1 Peter contains references to the persecution under Nero, that "fiery trial" (iv. 12) in which the mere being a Christian would lead to penal consequences (iv. 16), and in which, for conscience' sake, men would have to "endure griefs, suffering wrongfully" (ii. 19), thereby being "partakers of Christ's sufferings" (iv. 13). In which case 1 Peter cannot be placed earlier than A.D. 64, and the Epistle of James must be the earlier of the two. And it seems to be chiefly those who would make our Epistle a forgery of the second century (Brückner, Holtzmann) who consider that it is James that echoes 1 Peter, rather than 1 Peter that reproduces James. There is a powerful consensus of opinion[32] that if there is any influence of one writer upon the other, it is St. James who influences St. Peter, and not the other way.
We must not place the Epistle of St. James in or close after A.D. 50. The crisis respecting the treatment of Gentile converts was then at its height (Acts xv.); and it would be extraordinary if a letter written in the midst of the crisis, and by the person who took the leading part in dealing with it, should contain no allusion to it. The Epistle must be placed either before (A.D. 45-49) or some time after (A.D. 53-62) the so-called Council of Jerusalem. There is reason for believing that the controversy about compelling Gentiles to observe the Mosaic Law, although sharp and critical, was not very lasting. The _modus vivendi_ decreed by the Apostles was on the whole loyally accepted, and therefore a letter written a few years after it was promulgated would not of necessity take any notice of it. Indeed, to have revived the question again might have been impolitic, as implying either that there was still some doubt on the point, or that the Apostolic decision had proved futile.
