57. This is why angels are not angels in their own right but are angels by virtue of their union with the Divine-Human One; and their union depends on their acceptance of what is divinely good and what is divinely true. What is divinely good and what is divinely true are God, and seem to emanate from him even though they are within him. Their acceptance depends on the way angels apply the laws of his design, which are divine truths, to themselves, using their freedom to think and intend according to their reason, a freedom given them by God as their own possession. This is what enables them to accept what is divinely good and divinely true in apparent autonomy; and this in turn is what makes possible the mutual element in their love, for as already noted [48], love is not real unless it is mutual. It is the same with us here on earth.

All this enables us finally to see that everything in the created universe is a vessel for the divine love and wisdom of the Divine-Human One.

And because the angelic heaven is the final end, so, too, is mankind or the human race, since heaven is formed from it. It follows from this that all other phenomena created are intermediate ends, and that these are forms of use in the order, degree and respect that they have relation to mankind and through mankind to the Lord.
