Thanks for the suggestions. I'm working from a 3-ring binder of songs collected via photocopying and hand-transcription that a group of us used to sing and play from 30 years ago. I have no idea who scrawled this tune in. But, seeing as how most (if not all) of us were amateurs, it is very possible that the person doing the transcription got something wrong. I'm still bad enough at this that I wouldn't recognize "wrong". It's not an original. My initial thought was to, as much as possible, faithfully transcribe what I have in the binder.
The hand-writing is so bad that I had trouble deciphering the lyrics -- and the title, but digging around a bit, it appears to be an arrangement -- perhaps by one of our members from the now long-defunct group -- of "Adoramus te Christe". (Not one of the songs we did often enough for me to remember it.) The score looks to be SAB1B2 + Piano. And the lyrics that I can make out don't strictly follow the lyrics I'm finding online. I may try to dig up a more official and better-printed version, now that the feedback I'm getting is that the arrangement is "odd" in that section I was asking about.
