I covered this one in CWB I, but repeat it here so I can do an organ backing.
This is all Richard Connelly‘s work, text included. He called the tune SANDY BAY. The original sources are out of print but the sheet music is available these days at Willow.
Antiphon
Father, we praise You,
We your trusting people;
Father, we thank You,
Ruler and Creator,
Giver of all our joy.
1 Now to your altar, in answer to your call,
We come to give thanks to you and praise you.
2 Send forth the light of your truth to be our guide
And show us the way to our eternal home.
3 Lord, we are sinners, unworthy of your love,
And You are the Father who can pardon us.
4 Mary, our mother, and all your saints of God,
Remember us, pray for us before his throne.
