During the progress of the Antioch church and of the mission which had proceeded from it, the church at Jerusalem had not been idle. At the head of it stood James, the brother of Jesus, who was not one of the twelve apostles and apparently during the earthly ministry of Jesus had not been a believer, but who had witnessed an appearance of the risen Lord. James was apparently attached permanently to the church at Jerusalem, while the Twelve engaged frequently in missionary work elsewhere. From this James there has been preserved in the New Testament a letter, The Epistle of James, which is addressed "to the twelve tribes which are of the Dispersion." This letter was written at an early time, perhaps at about the time of the first missionary journey of Paul. In the letter, James lays stress upon the high moral standard which ought to prevail in the Christian life, and he has sometimes been regarded as an advocate of "works." But this judgment should not be misunderstood. The "works" of which James is speaking are not works which are to be put alongside of faith as one of the means by which salvation is to be obtained; they are, on the contrary, works which proceed from faith and show that faith is true faith. James does not, therefore, deny the doctrine of justification by faith alone. Only he insists that true faith always results in good works. Paul meant exactly the same thing when he spoke of "faith working through love." Gal. 5:6. Paul and James use somewhat different language, but they mean the same thing. Faith, according to both of them, involves receiving the power of God, which then results in a life of loving service. Acts 15:1-35; Galatians 2:1-10 The wonderful success of the first missionary journey of Paul and Barnabas caused great joy to the Antioch church. But the joy was soon marred by certain persons, commonly called "Judaizers," who came down to Antioch from Jerusalem and said that unless the Gentile converts kept the Law of Moses they could not be saved. The demand was directly contrary to the great principle of justification by faith alone; for it made salvation depend partly upon human merit. The entire life of the Church was in danger. But Paul, guided by a revelation from God, determined to comply with the wishes of the brethren at Antioch by going up to Jerusalem with Barnabas and certain others, in order to confer with the leaders of the Jerusalem church. Paul did not need any authorization from those leaders, for he had been commissioned directly by Christ; nor did he need to learn from them anything about the principles of the gospel, for the gospel had come to him through direct revelation. But he did desire to receive from the Jerusalem leaders, to whom the Judaizers falsely appealed, some such public pronouncement as would put the Judaizers clearly in the wrong and so stop their ruination of the Church's work.
