Going down the rabbit hole of hymnal archeology in the Praise to God collection has led me to this song they sourced from the Living Parish Hymn Book. It is another gorgeous Richard Connolly setting, but this time with his usual poet and wordsmith James P McAuley.
It really is a lovely poem set to music with themes suitable for Gifts. It is still in print, too, at Willow, where you can buy the sheet music. Better still they have the whole collection, Year of Grace. Looking at the sample at Willow, it is much better set out than the sheet music in PTG. The hymn is also in the Australian Hymnbook 587.
I got sick of organ and just did BIAB guitar for a backing, using chords manufactured from the organ music:
Antiphon
Our lives, O God, and all that we own we give;
Give us Your Son, by whom alone we live.
1 The fruits of earth, the bread and wine,
We lay upon the altar stone;
With them we offer and consign
All that we are and all we own.
2 God takes our whole created good,
Presented with the bread and wine;
Our human selves of flesh and blood,
Transformed in Christ, are made divine.
3 How poor the gift, how great the gain,
Ourselves we give, and Christ receive;
The Word who speaks no word in vain
Has promised this, and we believe.
