Chapter XIV. Each Person of the Trinity is said in the sacred writings to be Light. The Spirit is designated Fire by Isaiah, a figure of which Fire was seen in the bush by Moses, in the tongues of fire, and in Gideon's pitchers. And the Godhead of the same Spirit cannot be denied, since His operation is the same as that of the Father and of the Son, and He is also called the light and fire of the Lord's countenance. · Sacred Texts
