All Bach.
U2's albums are suffused with Christian themes. Bono says he is a devout Christian.
For some spectacular R&B/Gospel check out Leon Bridges album Coming Home. It is not a religious or gospel album per se but there are three of four excellent songs with Christian themes. On some of them you have to listen carefully to hear them. The songs are fantastic as is the whole album. The theology is deep and solid without being cheesy or in-your-face. This one, River, is probably the best and deepest:

I am a devout Christian but other than classical, traditional hymns and a few I've mentioned here, I do not particularly like religious music. Especially religious pop music. Several of you have mentioned above that it has gotten better, and that is good. Because not long ago I would have said it was the worst music of all. It wasn't good pop. It wasn't good gospel. No catchy tunes. Overly emotional and sentimental. Shallow and vapid. And that always makes me a little sad, as a Christian. As millercarbon mentioned, western religious music was, at one time, the highest level or artistic expression in music. And it might still be.
