1. Will I have to change anything I do?
You will need to know the same changes to sung and spoken responses and prayers as everyone else, and in particular the new texts that you will be asked to say instead of those you use at present. These are quite extensive and include: Invocations in the Penitential Rite, request for a blessing before proclaiming the Gospel, the announcement “The Gospel of the Lord” at the end of the Gospel, the four new dismissals at the end of Mass. You’ll also need to become used to a different altar missal and possibly other booklets during the time of transition from the old missal to the new one.

The new altar missal is due to be published in three formats:

(a) Altar edition: this will be quite heavy to hold and carry.
(b) Reduced-size edition, for use at the priest’s chair: this will be smaller and lighter, and will be missal that servers hold up for the priest to read from.
(c) Travelling edition: an even smaller edition for private study use and for priests or deacons on pilgrimages and other situations where it is not practicable to take a larger edition.

2. Are there any texts in the Mass that speak especially to my ministry?
Bearing in mind the threefold diaconal ministry of charity, word and altar, the following are useful for reflection: Ministry of Charity
Both the Eucharistic Prayers for Reconciliation
Ministry of the Word
The priest’s blessing of the deacon before the Gospel: May the Lord be in your heart and on your lips that you may proclaim his Gospel worthily and well . . .
Ministry at the Altar
In Eucharistic Prayer II: We offer you, Lord, the Bread of life and the Chalice of salvation, giving thanks that you have held us worthy to be in your presence and minister to you.
