 Saint Peter,
 Prince of the Apostles,
 St. Peter, to whom were given the keys
 of the Kingdom of Heaven,
 St. Peter, so ardent for the glory of Christ,
 St. Peter, whose heart was pierced with one look from Jesus,
 St. Peter, who ceased not to grieve for
 having denied the Son of God,
 St. Peter, whose cheeks were furrowed by a stream
 of tears which flowed to the end of thy life,
 St. Peter; who cried out, "Lord, Thou knowest that I love Thee."
 St. Peter, bound in chains for Christ,
 St. Peter, delivered from prison by an Angel,
 St. Peter, who rejoiced to suffer for Christ,
 St. Peter, whose very shadow healed the sick,
 St. Peter, whose voice even the dead obeyed,
 St. Peter, that we may have a constant
 and mutual charity among ourselves,
 That we may taste and see more and more how sweet is the Lord,
 That we may be zealous in loyalty to thy successor,
 the present Vicar of Christ,
 That we may help, at least by prayer, to restore to
 the unity of thy Holy See the scattered sheep,
 That we may be prudent and watchful in prayer,
 That we may die the death of the just,

V. Let the mercies of the Lord give glory to him,
R. And His wonderful works to the children of men.
 V. Pray for us, Saint Peter the Rock,
R. That we may be worthy of the Vicar of Christ.

Let Us Pray.

O Lord Jesus Christ, Who upon blessed Peter, Thine Apostle, didst bestow the pontifical power of binding and loosing, and didst give to him the keys of the Kingdom of Heaven, grant that his intercession may ensure our deliverance from the bondage of sin, Thou Who livest and reignest with the Father and the Holy Ghost, ever one God, world without end. R. Amen.
