Email is the preferred method of communication! Altar Servers at minimum must have received the Sacraments of Baptism and Communion; the Sacrament of Confirmation is not a requirement. Servers are expected to give their time and talent to their parish community, and are willing to serve God's people. They should also be able or at least willing to understand the Celebration of the Eucharist and other sacred rites.
The responsibilities of an Altar server include:
Carrying the cross and the processional candles.
Presenting the bread and wine along with the water to the priest in preparation of the gifts.
Cleaning up the altar after Communion.
Assisting the priest and deacon in whatever else they need help with.
