>>It isn’t pop.<<
You may know the history of that song, Pete in the Pew thinks Cat Stevens. To me, to my fellow parishioners, it’s pop, no matter where it came from.
AND it is not appropriate for the liturgy. While you may not find any of the words to be anti-Catholic, we are at Holy Mass for a reason.
We have an awful lot of dead wood and trash - truly rotten music - to get rid of before we start throwing out music because of mere passing associations. Then we can start weaning the congregation back onto the old Catholic stuff (but you have to make sure that they don't put that awful random leap into the middle of "Infinite thy vast domain". Shudder.)
Yes, we are, and one of those reasons is to PRAISE God, for the gift of His Son, and His awesome Creation. There is a lot of good music out there, and I, for one, as a choir member, love to try out the new stuff, as well as 'oldies, but goodies'.
