O God, who in Your providential
design willed that Your Church
be built upon blessed Peter, whom You
set over the other apostles, look with
favor, we pray, on Leo our Pope and
grant that he, whom You have made
Peter’s successor, may be for Your
people a visible source and
foundation of unity in faith and of
communion.

Through our Lord Jesus Christ, Your
Son, who lives and reigns with You in
the unity of the Holy Spirit, God, for ever
and ever.

Amen.
