I suppose if you were to predict who among these songwriters would still be in print Lucien Deiss would be a fair guess.
This song from A Hundredfold: A Contemporary Folk Hymnal, has survived to still be available at GIA here. He based the text on Exodus 34:6 and Deuteronomy 5:9-10 and it sounds a sung prayer of the faithful.
The verses are in Gm evoking mystery and are call and response between and choir or soloist and the assembly. The antiphon is in a more positive key of G. I’m trying to understand what makes this folk.
I reverted to the wind up BIAB fake organ for this backing:
Antiphon
God, full of mercy and God of compassion;
God rich in kindness and faithful in your love;
God, whi grants pardon to those who seek you,
And treasure your living word.
Verses

Reveal your name to me; show me the light of you face.
2.Lord, your mercy fills the earth: You, Lord are my Saviour!

God protector of the week: You, Lord are my love;

4 God, the Mystery of light: You, Lord are my Saviour!
God, revealed through Christ your son: You, Lord are my love;
Reveal your name to me; show me the light of you face.
