I half read your post, and was ready to quote an OCP publication regarding hymns, songs and psalms.
Us good Catholics will partake of hymms, that were not originally written for Catholic service. For those wondering just a few,
Lord of the Dance; Shaker hymn
Were you there?; spiritual
Away in the Manager; Lutheran,
Amazing Grace; Church of England?
possibly Silent Night
10,000 reasons;
Maybe we need a new thread, "Acquired worship music and its sources"
@gregbackstrom, would you like to start it, I will post more. I hope the moderators would find such a thread relevant, as we would be discussing the history of the music, and not its religiosity. See post 54, for similar reasoning.
