Confirmation is an opportunity to renew your baptism vows, especially if they were made by someone on your behalf when you were a child. It is asking God to fill you with his Holy Spirit as a mature Christian, and means accepting your own responsibilities within the Church.
Confirmation is always given by the Bishop at a special service. If you would like to know more please talk with the Vicar. Traditionally, Anglicans have only been allowed to receive the bread and wine at Holy Communion after Confirmation. Although this is not insisted upon any more, many people like to keep this discipline as a special mark of their own discipleship.
