My survey of Catholic Worship Book II is skipping all those already blogged in other collections and what remains is mainly older texts with even older tunes.
This one is at least c20 and has a text for Eucharist by Anthony Nye SJ.
CWB II sets it to the old Scottish tune, MARTYRDOM, which Godsongs notes as commonly in use in Australia and New Zealand while IRISH is the setting used in the UK.
O God we give ourselves today
With this pure host to thee,
The self same gift which thy dear Son
Gave once on Calvary.Entire and whole our life and love
With heart and soul and mind.
For all our sins and faults and needs,
Thy Church and all mankind.With humble and with contrite heart
This bread and wine we give,
Because thy Son once gave himself
And died that we might live.Though lowly now, soon by thy word
This bread and wine will be
The very body of our Lord
His soul and deity.His very body, offered up
A gift beyond all price.
He gives to us, that we may give,
In loving sacrifice.O Lord, who took our human life,
As water mixed with wine,
Grant through this sacrifice that we
May share thy life divine.
