Here’s a litany of Christian Unity from the World Council of Churches (2011).
Litany
In Christ, the world is reconciled to God who entrusts to us the message of reconciliation. As the ambassadors of Christ’s reconciling work, we make our petitions to God:
When we pray together from our diverse traditions,
Holy One who makes us one,
make our unity visible and bring healing to the world.
When we read the Bible together
in our diversity of language and context,
Revealing One who makes us one,
make our unity visible and bring healing to the world.
When we establish relations of friendships
among Jews, Christians and Muslims,
when we tear down the wall of indifference and hatred,
Merciful One who makes us one,
make our unity visible and bring healing to the world.
When we work for justice and solidarity,
when we move from fear to confidence,
Strengthening One who makes us one,
make our unity visible and bring healing to the world.
Wherever there is suffering through war and violence,
injustice and inequality, disease and prejudice,
poverty and hopelessness,
drawing us near to the cross of Christ and to each other,
Wounded One who makes us one,
make our unity visible and bring healing to the world.
With Christians of the Holy Land,
we too are witnesses to the birth of Jesus Christ in Bethlehem,
his ministry in Galilee, his death and resurrection,
and the descent of the Holy Spirit in Jerusalem;
when we yearn for peace and justice for all
in the sure and certain hope of your coming Kingdom,
Triune One who makes us one,
make our unity visible and bring healing to the world.
