Let us pray
For all our brothers and sisters
Who share our faith in Jesus Christ,
That God may gather and keep together in one church
All those who seek the truth with sincerity.
Almighty and eternal God,
You keep together those you have united.
Look kindly on all who follow Jesus your Son.
We are all consecrated to you by our common baptism.
Make us one in the fullness of faith,
And keep us one in the fellowship of love.
We ask this through Christ our Lord.
