I don't have a problem with saying it, since the Bible says it. But, I admit, I'm a bit hazy as to what the Bible means by it. Well, let's put it this way: when I consider that creatures love -- and often love evil -- it makes me think that not all love could be the love that the Bible says God is. But in the text, no "some" or "all" quantifier is used next to "love", as in "God is some, but not all love," or "God is all love". Yeah, when it comes down to it, unfortunately, I'm definitely not well-studied or certain on the question of what exactly is meant by that.
I'm very certain that there isn't anyone on Earth who is certain on the question of what EXACTLY is meant by, "God is Love".
"God is loving" is a lot easier, obviously, but "God is Love"? What could that mean? I do not know. I mean, there's plenty to say about various things in that direction, but none of it really settles the question.
One of the things I happen to like very much about my theology proper is that when there are mysteries that are beyond my grasp, they never take the form of absurdities. That is, I don’t have to believe that God is somehow arbitrarily just or dynamically immutable or any other such contradictory nonsense. “God is Love” is mysterious, yes, but it is not irrational. It’s profound, not dumbfounding. It’s a truth that stretches the mind, but not one that breaks it.
And that’s actually one of the reasons I find “God is Reason” to be such a powerful and clarifying truth. Love becomes meaningful only when it is grounded in something rational, something with coherence, purpose, and moral substance. Without reason, love could be anything, even the kind of love that leads a person to embrace what is evil. Pete Buttigieg actually believes he loves his "husband". The fact is that he hates both him and himself and is destroying both. The kind of love that God is, on the other hand, must be perfectly rational, pure, righteous, principled and truly relational.
So I think the statement, “God is Love” and the statement, “God is Reason” are not just both true, they actually require each other. If God were not Reason, then His love would lose its moral clarity. If God were not Love, then His reason would be cold and impersonal (i.e. not love at all). When we see both as essential to His being, when we see love as rational and reason
as loving, then perhaps we start to glimpse something of what these deep statements might really mean.
