Here is the piece we are working on right now in our parish choir. The lines are long, the drama intense, and the text somehow emerges above it all thanks to some very clever voicing.
Honor, virtus et potestas et imperium sit trinitati in unitate,
unitati in trinitate, in perenni saeculorum tempore.
Trinitati lux perennis, unitati sit decus perpetim.
Gloria Patri et Filio et Spiritui Sancto.
Honour, strength and might and power be to the Three in One,
the One in Three, throughout eternal ages.
To the Trinity be endless light, to the Unity be perpetual glory.
Glory be to the Father, and to the Son, and to the Holy Ghost.
