Antiphon.

That they may all be one, as You, Father, in Me and I in You;
that they so may be one in Us,
that the world may believe that You have sent Me. (John 17:21)

V. I say unto you, that you are Peter.
R. And upon this rock I will build My Church.

Let us pray.

O Lord Jesus Christ,
You said to Your Apostles:
"Peace I leave with you, My peace I give to you."
Look not upon our sins, but upon the faith of Your Church,
and grant to her that peace and unity
which are agreeable to Your will,
who live and are King and God,
for ever and ever.

R. Amen.
