Quite right. We can and should bemoan any coarsening of language, including any once-expressive words that have become reduced to mostly sexual meanings. But bemoaning that reality doesn’t mean ignoring that reality.
Another example springs to mind - would we ever say that Jesus was gay, or had a gay time? Or would we have enough common sense to know that this word today means something different than it used to mean?
When did the Church ever use the word “gay” to refer to Our Lord?
Besides, we’re not talking about lover
not meaning lover in the sense of a husband. We’re not restricting it to mean “someone who loves”. Rather, we are using metaphorical language of a relationship parallel to that of husband and wife, as when we refer to the Lord as our Shepherd.
Unlike the word “gay”, the sexual connotation was always there when God was depicted as a lover in the Scriptures, as in the Song of Songs. Hosea referred to Israel as a whore. The only thing that has changed is what it means when something has a sexual connotation put on it. A sexual relationship is meant to be an entirely wholesome and holy thing. We must absolutely guard that attitude toward what sexuality is, and continue to be adamant about what sexuality is not, particularly in catechesizing our young people.
IMO, when we restrict the metaphors we use for God as Father and Shepherd, it becomes a way of infantalizing ourselves, of not being willing to commit fully or to fully admit the gravity of our sins. We are commanded to love and commit ourselves to God in a complete and adult sense, not just as children are attached to their parents or as sheep are dependent on their shepherd (although those metaphors fit, too), but, as the Body of Christ, as a wife faithfullly and totally committed to her husband. (And please, let’s not get off on what some people want “adult” to mean “in these days”!!)
We owe God that kind of complete fidelity, and God gives His Church that kind of intimacy, dignity, and splendor. When we choose to act otherwise, we can fairly be described as being responsible for our infidelities in an adult sense, as well. We are not just making mistakes like children or wandering off like sheep but truly committing acts of betrayal parallel to a cheating spouse.
Again, like or don’t like the song, but in doing so don’t diminish what God has always intended every pair of lovers to be. The metaphor cuts both ways, after all!
