So the just man in charity is also his own friend while the sinner because of lack of charity is his own enemy. Again this same line of reasoning applies to love of our bodies. For love of God, charity, we must love our bodies which were made by God. We cannot separate our souls from the body in this Divine friendship. Our bodies also take part in the Divine life - most clearly in their resurrection.
Spiritual beings are also within our sphere of friendship.
They share an active friendship with God and also are His creatures. The fallen angels, on the other hand, are not friends of God. They have no potential friendship with our Divine friend. The only possible avenue for the extension of our love by charity to them would pertain to their nature as angels. Their nature belongs to God and is good - that is all.
