The dominant idea in the Christian community, at the moment at which we are now arrived, was the coming of the Holy Spirit. People were believed to receive it in the form of a mysterious breath, which passed over the assembly. Every inward consolation, every bold movement, every flush of enthusiasm, every feeling of lively and pleasant gayety, which was experienced without knowing whence it came, was the work of the Spirit. These simple consciences referred, as usual, to some exterior cause the exquisite sentiments which were being created in them. When all were assembled, and when they awaited in silence inspiration from on high, a murmur, any noise whatever, was believed to be the coming of the Spirit. In the early times, it was the apparitions of Jesus which were produced in this manner. Now the turn of ideas had changed. It was the divine breath which passed over the little Church, and filled it with a celestial effluvium. These beliefs were strengthened by notions drawn from the Old Testament. The prophetic spirit is represented in the Hebrew books as a breathing which penetrates man and inspires him. In the beautiful vision of Elijah, God passes by in the form of a gentle wind, which produces a slight rustling noise. Among all these "descents of the Spirit," which appear to have been frequent enough, there was one which left a profound impression on the nascent Church. One day, when the brethren were assembled, a thunder-storm burst forth. A violent wind threw open the windows: the heavens were on fire. Thunder-storms, in these countries, are accompanied by prodigious sheets of lightning; the atmosphere is, as it were, everywhere furrowed with ridges of flame. Whether the electric fluid had penetrated the room itself or whether a dazzling flash of lightning had suddenly illuminated the faces of all, everyone was convinced that the Spirit had entered, and that it had alighted on the head of each in the form of tongues of fire. The idea that the Spirit had alighted on them in the form of jets of flame, resembling tongues of fire, gave rise to a series of singular ideas, which took a foremost place in the thought of the period.
