This Trinitarian hymn is new to me though rather old. I like the fact that it at least does say something about the Trinity.
The text (with some alt) is by Edward Cooper (1770-1833) and it is set to SONG 5 by Orlando Gibbons (1583-1625).
I got the chords from Liturgy Share and made a stodgy backing, but that’s my fault:
1 Father of heaven, whose love profound
A ransom for our souls hath found,
Before your throne we sinners bend;
To us your saving love extend.
2 Almighty Son, incarnate Word,
Our Prophet, Priest, Redeemer, Lord,
Before your throne we sinners bend;
To us your saving grace extend.
3 Eternal Spirit, by whose breath
The soul is raised from sin and death,
Before your throne we sinners bend;
To us your quickening power extend.
4 Thrice holy — Father, Spirit, of
Mysterious Godhead, Three in One,
Before your throne we sinners bend;
Grace, pardon, life to us extend.
