Thou shalt make the Princes over all the earth:
They shall remember thy name, O Lord.
Instead of thy fathers, Sons are born to thee:
Therefore shall the people praise thee, Alleluia.
Tu es Petrus
Et super hanc petram
Ecclesiam meam. Alleluia.
Thou art Peter,
And upon this rock
I will build
my church. Alleluia.
from the Gradual of the Feast of St Peter and St Paul
