That the Epistle should at first remain very little known, especially in the West and among the Gentile congregations, is exactly what we should expect from the character of the letter and the circumstances of its publication. It is addressed by a Jew to Jews, by one who never moved from the Church over which he presided at Jerusalem to those humble and obscure Christians outside Palestine who, by their conscientious retention of the Law side by side with the Gospel, cut themselves off more and more from free intercourse with other Christians, whether Gentile converts or more liberally-minded Jews. A letter which in the first instance was to be read in Christian _synagogues_ (James ii. 2) might easily remain a long time without becoming known to Churches which from the outset had adopted the principles laid down in St. Paul's Epistle to the Galatians. The constant journeys of the Apostle of the Gentiles caused his letters to become well known throughout the Churches at a very early date. But the first Bishop of the Mother Church of Jerusalem had no such advantages. Great as was his influence in his own sphere, with a rank equal to that of an Apostle, yet he was not well known outside that sphere, and he himself seems never to have travelled beyond it, or even to have left the centre of it. With outsiders, who simply knew that he was not one of the Twelve, his influence would not be great; and a letter emanating from him, even if known to exist, would not be eagerly inquired after or carefully circulated. Gentile prejudice against Jewish Christians would still further contribute to keep in the background a letter which was specially addressed to Jewish Christians, and was also itself distinctly Jewish in tone. Nor would the exclusive class of believers to whom the letter was sent care to make it known to those Christians from whom they habitually kept aloof. Thus the prejudices of both sides contributed to prevent the Epistle from circulating outside the somewhat narrow circle to which it was in the first instance addressed; and there is therefore nothing surprising in its being unknown to Irenæus, Hippolytus, Tertullian, Cyprian, and the author of the Muratorian Canon. There is no sign that these writers _rejected_ it; they had never heard of it.[12]
