To-day Christianity is of different portent. But in those days the enthusiasts, visionaries, and saints did not clearly know what Christianity was: Christianity was not clear to them; they sensed it, it had possession of them, they were in a state of exaltation because of it. Christianity was growing through them, growing deeper. Their intellectual conceptions of what Christianity was and was not were often quite mistaken—but the vision they could not express was authentic. The new idea was in the air. Hence, for instance, the gift of tongues. People listening to the apostles were caught by the idea, even though the language spoken was foreign to them. Christianity was imparted by enthusiasm alone, by the gait, the gesture, the expression of countenance of the believer, the living hieroglyphic; and it did not matter that the apostles spoke one language and the listener another. The spirit of truth sat in the faces of the apostles like tongues of fire and spoke for them. In those days many who had never seen an apostle dreamed and became Christians, heard a voice from heaven, were struck blind by the heavenly vision like Saul, whose mind on the way to Damascus was far from Christianity, but whose soul was so near that even at the stoning of Stephen there could have been but the thinnest partition between him and the great splendour. Many people in those days went about in strange apprehension—as if the world were coming to an end, and quite truly a world, that of the Romans, was coming to an end—and suddenly they were aware of the mystery, and without a word of proselytism gave up everything and went to the desert.
