Well I pretty sure the French carols I sang in college madrigals were written by Catholics! “I Saw Three Ships”, “Torches, Torches”, “Strike the Torch, Jeannette, Isabella” Not that whose are popular ones any more (i.e., in the last several centuries), but I still love them.
Anyone know about the author of Cantique d’ Noel (O Holy Night)? I got a good story about that… my daughter was asked to sing at a Christmas service, picked that, and learned the words in French. (She had like 6 years of French in her jr. and sr. high school.) She told us that the French word translated “weary” in “a weary world rejoices” has a lot stronger meaning than just “tired”… it’s closer to “despairing, hopeless”. Knowing that, I like the song even more.
