The following prayer is taken from the Roman Missal. A partial indulgence is attached to the versicle and response.
V. Oremus pro Pontifice nostro Benedicto.
R. Dominus conservet eum, et vivificet eum, et beatum faciat eum in terra, et non tradat eum in animam inimicorum eius. [Ps 40:3]
Deus, omnium fidelium pastor et rector, famulum tuum Benedicto, quem pastorem Ecclesiae tuae praeesse voluisti, propitius respice: da ei, quaesumus, verbo et exemplo, quibus praeest, proficere: ut ad vitam, una cum grege sibi credito, perveniat sempiternam. Per Christum, Dominum nostrum. Amen.
V. Let us pray for Benedict, our Pope.
R. May the Lord preserve him, and give him life, and make him blessed upon the earth, and deliver him not up to the will of his enemies. [Ps 40:3]
Our Father, Hail Mary.
O God, Shepherd and Ruler of all Thy faithful people, look mercifully upon Thy servant Benedict, whom Thou hast chosen as shepherd to preside over Thy Church. Grant him, we beseech Thee, that by his word and example, he may edify those over whom he hath charge, so that together with the flock committed to him, may he attain everlasting life. Through Christ our Lord. Amen.
