Book of Common Prayer (page 512)

The Ordination of a Bishop

Hymns, psalms, and anthems may be sung during the entrance of the
bishops and other ministers.

The people standing, the Bishop appointed says

Blessed be God: Father, Son, and Holy Spirit.

People And blessed be his kingdom, now and for ever. Amen.

In place of the above, from Easter Day through the Day of Pentecost

Bishop Alleluia. Christ is risen.

People The Lord is risen indeed. Alleluia.

In Lent and on other penitential occasions

Bishop Bless the Lord who forgives all our sins.

People His mercy endures for ever.

The Bishop then says

Almighty God, to you all hearts are open, all desires known,
and from you no secrets are hid. Cleanse the thoughts of our
hearts by the inspiration of your Holy Spirit, that we may
perfectly love you, and worthily magnify your holy Name;
through Christ our Lord. Amen.
