Worth considering…

We may give our human loves the unconditional allegiance which we owe only to God. Then they become gods: then they become demons. Then they will destroy us, and also destroy themselves. For natural loves that are allowed to become gods do not remain loves. They are still called so, but can become in fact complicated forms of hatred.
