I ran across this while looking for something else I believe. This is a song written by Marty Haugen for Lutheran services.
The refrain is singable but each verse has a different tune – but Lutherans sing better than Catholics so I’m sure it’s fine.
The text was difficult to find but there is a powerpoint of it on the web if you Google it, that I can’t find a way to link to.
The sheet music is available from GIA in a very inexpensive collection.
This one starts at 1.00
