O God,

by your Word

you marvelously worked out

the reconciliation of humanity.

During this holy fast

may we devote ourselves to you with all our hearts,

and be united with each other in prayer to you;

through Jesus Christ our Lord.

I pray also for those who will believe in me through their message, that all of them may be one, Father, just as you are in me and I am in you. May they also be in us so that the world may believe that you have sent me. I have given them the glory that you gave me, that they may be one as we are one
