God, Your name is glorious

[Guest]

We sang this incredible hymn during Trinity Sunday Mass today, but I can't seem to find it anywhere! It goes something like this: "God, Your name is glorious; it resounds throughout the earth." It was beautiful -- haunting, even! We sang it as our responsorial psalm, and during the part where only the cantor sings, the melody was very high and sort of 'floaty'.

Thanks so much! God bless!
