When, then, we have perceived these things and are conducted from these to the divine essence, we do not apprehend the essence itself but only the attributes of the essence: just as we have not apprehended the essence of the soul even when we have learnt that it is incorporeal and without magnitude and form: nor again, the essence of the body when we know that it is white or black, but only the attributes of the essence. Further, the true doctrine ὁ δὲ ἀληθὴς λόγος. teacheth that the Deity is simple and has one simple energy, good and energising in all things, just as the sun’s ray, which warms all things and energises in each in harmony with its natural aptitude and receptive power, having obtained this form of energy from God, its Maker.
