(2) There was another feature of early Christian life which probably contributed more than anything else to strengthen this tendency. It was the habit of intercourse and intercommunion. Christians, like Jews, travelled widely—more for trade and commerce than for pleasure. The new brotherhood of Christians, like the ancient brotherhood of the Jews, gave to all the travelling brethren a welcome and hospitality. A test had been necessary in the earliest times in regard to the prophets and teachers. It is mentioned in the Teaching of the Apostles. But the test was of moral rather than of intellectual teaching. “Whoever comes to you and teaches you all these things” (i.e. the moral precepts of the “Two Ways”), “receive him. But in case he who teaches, himself turns and teaches you another teaching[722] so as to destroy (this teaching), listen not to him: but if he teaches you so as to add to your righteousness and knowledge of the Lord, receive him as the Lord.”[723] So of the prophets: “Not every one who speaks in the spirit is a prophet, but only he who has the moral ways of the Lord (τοὺς τρόπους Κυρίου): by these ways shall be known the false prophet and the true prophet.... Every prophet who teaches the truth, if he does not what he teaches, is a false prophet.”[724] So also of the travelling brethren: “Let every one who comes in the name of the Lord be received; afterwards ye shall test him and find out.... If he wish to settle among you and is a craftsman, let him work and so eat. If he be not a craftsman, provide some way of his living among you as a Christian, but not being idle. If he be unwilling so to do, he is χριστέμπορος—making a gain of godliness.”[725]
