What ought to be our verdict on this claim of the first Christians? To see the question in its true light it is necessary to distinguish between the experience of the Christians and the opinion which they held about it. Their opinion was that they had been taken possession of by the Spirit of God, which was acting through them, so that their words and deeds had the authority no longer of fallible man but of the omnipotent and infallible God. This theory was a heritage from a distant past in Israel {42} when the Spirit of the Lord had been regarded as the source of all extraordinary events, good or evil. Later, evil events had no longer been attributed to the Spirit of the Lord, but to demons or unclean spirits who peopled the earth and took possession of men as they found opportunity. To them were attributed disease, misfortune, and especially the raving of madness, while healing and prophecy were attributed to the Divine Spirit. In modern times we no longer attribute disease, misfortune, or madness to devils, not because these phenomena have ceased, but because we have a different theory of their origin, which, on the whole, produces more satisfactory therapeutic results than the theory of possession. Similarly the phenomena of prophecy, which the Jews ascribed to the Spirit of God, remain. There has never been a generation lacking in men who believe that their action and speech are being governed by a compelling force, separate from the ordinary process of volition. Those who have this experience seem to themselves to be, as it were, the spectators of their own deeds, or to be listening to their own utterances. Under its influence individuals, groups of men, or even nations, are carried away by inexplicable waves of passion or enthusiasm which, once aroused, cannot be resisted till their force is spent. This consciousness has been felt in varying degree in every generation, and the progress of humanity can never be explained unless it be taken into account. Sometimes, in the inevitable {43} reaction after the psychic stress of such experiences, men have resented, doubted, or denied the validity of their own consciousness; sometimes they have regarded it as possessing a value exceeding all else in life. Usually those who have it attract the hostility of their contemporaries, scarcely tempered by the allegiance of a few followers, and their names are forgotten in a few years, but sometimes the verdict of contemporary hatred is reversed by posterity, which endeavours to compensate by legendary honours for the contempt and contumely of life. The problem presented by this experience is really twofold. It calls for a judgement as to its origin and for a judgement as to its value, and on neither point has there as yet been sufficiently clear discussion.
