Book of Common Prayer (page 564)

Except on Major Feasts, the Preface may be that for Apostles and
Ordinations.

After Communion

At the Induction of a priest or deacon, in place of the usual
postcommunion prayer, the Bishop leads the people in the following
prayer; but if the new minister is a lay person, the usual postcommunion
prayer is used.

Almighty Father, we thank you for feeding us with the holy
food of the Body and Blood of your Son, and for uniting us
through him in the fellowship of your Holy Spirit. We thank
you for raising up among us faithful servants for the ministry
of your Word and Sacraments. We pray that N may be to us
an effective example in word and action, in love and patience,
and in holiness of life. Grant that we, with him, may serve
you now, and always rejoice in your glory; through Jesus
Christ your Son our Lord, who lives and reigns with you and
the Holy Spirit, one God, now and for ever. Amen.

A newly inducted Priest may, at the bishop's request, pronounce a
blessing.

A Deacon, or a Priest if no deacon is present, dismisses the assembly.

Additional Directions

The Institution, the Ministry of the Word, and the Induction should
occur at the entrance of the chancel, or in some other place where the
bishop and other ministers may be clearly seen and heard by the people.

*The Letter of Institution is appropriate for the induction of a rector
of a parish, the dean of a cathedral, and others having similar tenure
of office.
