You will need to ask
(a) readers for the Scripture Readings: be sure to ask people who can read God’s Word well.
(b) a Eucharistic Minister, if there are more than fifty guests.
(c) readers for the Prayer of the Faithful: these can read one or more prayers depending on how many different readers you wish to include
(d) two people to bring forward the Bread and Wine at the Offertory of the Mass: this might be the mother of the bride and the mother of the groom
(e) two ushers to distribute booklets if they are used: ushers should stand up the aisle of the church so as to encourage guests to move nearer the front.
