Mysticism and Christianity by B. B. Warfield

RELIGION is, shortly, the reaction of the human soul in the presence of God. As God is as much a part of the environment of man as the earth on which he stands, no man can escape from religion any more than he can escape from gravitation. But though every man necessarily reacts to God, men react of course diversely, each according to his nature, or perhaps we would better say, each according to his temperament. Thus, broadly speaking, three main types of religion arise, corresponding to the three main varieties of the activity of the human spirit, intellectual, emotional, and voluntary. According as the intellect, sensibility, or will is dominant in him, each man produces for himself a religion prevailingly of the intellect, sensibility, or active will; and all the religions which men have made for themselves find places somewhere among these three types, as they produce themselves more or less purely, or variously intermingle with one another.
