Christ our Passover is sacrificed for us. 1 Corinthians 5:7
Words: William H. H. Jervois, in The English Hymnal (London: Oxford University Press, 1906), number 335.
If you know where to get a good photo of Jervois (head-and-shoulders, at least 200×300 pixels), would you ?
Wherefore, O Father, we Thy humble servants
Here bring before Thee Christ, Thy well belovèd,
All perfect offering, sacrifice immortal,
See now Thy children, making intercession
Through Him our Savior, Son of God incarnate,
For all Thy people, living and departed,
Pleading before Thee.
