If you decide to use any part of the setting please let me know at gsf@missaexcorde.org -- feedback is hard to come by on the internet when you're not selling something.  I can also set up a hymnal insert PDF document specific to your congregation.  If others are interested in the setting please direct them to this site.
A note to instrumentalists: take a little time to study the keyboard and guitar chord charts in the appendix of the vocal-guitar music.  The guitar chords are pretty much worked out for each composition; the keyboard chords are more of a guide until the keyboard arrangement is complete.  Substituting simple triads for the suspended seconds/fourths and pedal bass notes will deaden the overall sound.  The seconds flirt between major and minor in some passages but don't quite commit, and that adds a shimmer that the simpler chords don't capture.
