Chapter 51. Each loves himself and the other with equal love. (Monologium (Meditations on the Being of God)) (Anselm of Canterbury, St.)

But if the supreme Spirit loves himself, no doubt the Father loves himself, the Son loves himself, and the one the other; since the Father separately is the supreme Spirit, and the Son separately is the supreme

Spirit, and both at once one Spirit. And, since each equally remembers himself and the other, and conceives equally of himself and the other; and since what is loved, or loves in the Father, or in the Son, is altogether the same, necessarily each loves himself and the other with an equal love.
