Truth

We do not know precisely what was happening to the churches to whom John was writing, of course. We know that at the very least there was a schism in which those who professed to have greater knowledge in spiritual matters withdrew from the original Christian assembly.

In these verses John deals with this problem of the need to discern teaching in the church and, therefore, also with our own need to exercise such discernment. His reply has three parts. First, there is the command to test those who claim to be inspired. Second, there is a standard to be used in testing them. Third, there is an application of these ideas to the problem of distinguishing between true and merely professing Christians. In this last section John deals once more with the radical distinction between the church and the world and shows the relation of each to the apostolic doctrine.

John has already indicated that behind every prophet stands a spirit, either the Spirit of God or the demonic spirit of antichrist (v. 3). He has spoken of the need to test the spirits by their origin. But how are they to be tested? How can a normal Christian know whether the spirit is of God or of antichrist? Here John applies precisely the test given in Deuteronomy 13, though in terms appropriate to the situation occasioned by the Gnostic challenge. “What do they say about Christ?” is John’s question. Do they acknowledge that Jesus is the Christ come in the flesh or do they deny this? If they deny Christ, they are not of God no matter how marvelous their activity.

At this point we may feel that the discussion has become somewhat theoretical and even unreal, for we are not often confronted today by those who claim to be prophets. Our difficulty is rather of knowing on the purely human level whether or not a teacher speaks truly. Can we test those who speak on this level? Can truth be distinguished from error here? The objection is valid, of course, and the questions are good ones. Consequently, we are not surprised to find John turning to deal with this matter in the remaining verses.

The tragedy of our time is that we have not enough men and women to proclaim and defend that doctrine. So the truth is not clearly defined, and the way is not clearly illuminated. The doctrine of the apostles, the only true doctrine of the church, illuminates it; and the incarnation of God’s Christ defines and gives a focal point to that doctrine. It is for us to determine whether or not we believe that doctrine and, if we do, to respond to it. There are not three ways, according to the apostle. There are not four, or five, or more. There are only two ways: the way of truth and the way of error, the way of Christ and the way of antichrist. We are called to serve Christ, and those who are truly of God will do so.
