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, and at St Peter's our candidates are usually presented at the Abbey once a year on Easter Eve. One of the clergy will help you prepare for this service in the way which will best help you think about its grace and opportunities.
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.
