Proslogium; Monologium; and Cur Deus Homo
Chapter LIII.
Medieval Anselm of Canterbury EnglishEach loves himself and the other with equal love.
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.
This love is as great as the supreme Spirit himself.
How great, then, is this love of the supreme Spirit, common as it is to Father and Son! But, if he loves himself as much as he remembers and conceives of himself; and, moreover, remembers and conceives of himself in as great a degree as that in which his essence exists, since otherwise it cannot exist; undoubtedly his love is as great as he himself is.
This love is identical with the supreme Spirit, and yet it is itself with the Father and the Son one spirit
But what can be equal to the supreme Spirit, except the supreme Spirit? That love is, then, the supreme Spirit. Hence, if no creature, that is, if nothing other than the supreme Spirit, the Father and the Son, ever existed; nevertheless, Father and Son would love themselves and one another.
It therefore follows that this love is nothing else than what the Father and the Son are, which is the supreme Being. But, since there cannot be more than one supreme Being, what inference can be more necessary than that Father and Son and the love of both are one supreme Being? Therefore, this love is supreme Wisdom, supreme Truth, the supreme Good, and whatsoever can be attributed to the substance of the supreme Spirit.
