Richard of St. Victor’s De Trinitate, Ch.19 (Joseph)

Here Richard spells out more fully than before the nature of shared love (condilectus). Here he offers one main argument (A.1-3) from supreme shared love for the Trinity and then a follow-up argument (B.1-3) again from supreme shared love for the Trinity. So (A) consider the nature of shared love:

1. If one person loves another and only he loves only her, there is love but not shared love.
2. If two mutually love only each other (if the affection of each goes out to the other), again there is love but not shared love.
3. Shared love exists only if a third person is loved by two persons jointly:

“Shared love is properly said to exist when a third person is loved by two persons harmoniously and in community, and the affection of the two persons is fused into one affection by the flame of love for the third.” (Richard of St. Victor, On the Trinity, p.392)

(This is as close as we ever get to a characterization of shared love.)

So, in divinity, if there is shared love, there are at least three persons. So supreme shared love requires at least three divine persons. Supreme shared love is of a kind that no creature could merit it or be worthy of it from its divine creator.

Next (B) consider further the nature of shared loved as a virtue:

1. Supreme benevolence is supremely great. Supreme harmony is also supremely great. Each such virtue is of great value.
2. Any virtue that results from the combination of each such virtue is also supremely great.
3. But supreme shared love results from the combination of supreme benevolence and harmony. Such a virtue can’t be lacking in what is perfectly good. And supreme shared love can’t exist without at least three persons.

Therefore, in divinity, if there is at least one person, there are at least three persons.

There’s a lot here. Much of it we have in effect already seen. I want to make only one comment about (A1). This doesn’t exactly say what Richard wants to say here. If one person loves another and only the first loves the second, then no one else loves the second. And if, in addition, the first loves only the second, then the first loves no one else. But it’s clear that Richard wants an example of unrequited love to contrast with his second example of mutual love between two persons alone.

For what it’s worth, I think there’s something deeply insightful here about the value of shared love. And even if we don’t think something like the following. The fact that any perfect being is essentially perfectly good is a reason to think that it must be that if there is some perfect being, then there is also another perfect being or even just some created being. Even if we don’t think this, so I say, perhaps we can agree that if there were three divine persons, there would be a distinctive kind of goodness in the world because of the existence of supreme shared love, one which wouldn’t exist if there were only two divine persons or even only one. If so, that is something for a Christian to recognize and celebrate.

That’s it for me on this series. Next up is Dale, who will bring us home: blogging on chs.20-25.
