This is a song by Jean Lebon, the French liturgist, with the text translated by Pamela Stotter. It is the whole Easter story in song.
I’ve had no luck finding the sheet music outside of CWB I, but I don’t understand French so can’t search for Lebon’s original. My backing has my approximate chords. The antiphon is in C and the verses modulate to Eb. Looking this change up now suggests I should have used a G chord to get from the chorus the verse more smoothly – I didn’t as I have no music theory I’m afraid.
Antiphon
Christ is our Lord, he gives us life abundant.
Christ is our joy, we are one in him.
1 When the the time had come to return to his Father
And knowing that his hour was drawing near,
He longed to share the Pasch with his friends.
2 That he might celebrate the new covenant with all his men,
The Lord gives his body and his blood,
To reconcile all men to God once more.
3 The cross of Christ brings joy and slavation to all.
Our sins he has borne upon the tree.
His death brought life, and set all people free.
4 While Jesus slept in death, his disciples were dismayed.
So fearful in their loneliness and doubt,
But he arose and showed himself alive.
5 A stranger joined two friends who were talking of Jesus.
Their hearts burned within them as he spoke.
He broke the bread, they recognised the Lord.
6 “Peace be to you,” Jesus said to his disciples.
“Why are you afraid and full of doubt?”
With joy filled hearts they greeted Christ, their Lord.
7 Ascending to his Father, he speaks to his Church.
“Proclaim to all men the living word.”
The promised Christ has come to save the world.
