The love of God is unitive

Image: Thomas Aquinas (1225-1274)

The love of God is unitive, in as much as it draws man's affections from the many to the one; so that the virtues, which flow from the love of God, are connected together. But self-love disunites man's affections among different things, in so far as man loves himself, by desiring for himself temporal goods, which are various and of many kinds: hence vices and sins, which arise from self-love, are not connected together.
