Apocalypse Revealed#467
467. And his face was like the sun. That this symbolizes the Lord's Divine love and at the same time Divine wisdom is apparent from the explanation in no. 53 above, where similar things are said of the Son of Man.
Doctrine of the Sacred Scripture#27
27. The Word’s Literal Sense Is the Foundation, Containing Vessel and Buttress of Its Spiritual and Celestial Meanings
Every Divine work has in it a first, intermediate, and final element, and the first one progresses through the intermediate one to the final one, and so takes form and endures. Thus the final element is the foundation. Moreover, the first element is present in the intermediate one, and present through the intermediate one in the final one. Thus the final element is the containing vessel. And because the final element is the containing vessel and foundation, it is also the buttress.
