Confirmation is the sacramental rite in which the candidates "express a mature commitment to Christ, and receive strength from the Holy Spirit through prayer and the laying on of hands by a bishop" (BCP, p. 860). Those who were baptized at an early age and those baptized as adults without laying on of hands by a bishop are expected to make a mature public affirmation of their faith, recommit themselves to the responsibilities of their baptism, and receive laying on of hands by a bishop (BCP, p. 412). Adults baptized with the laying on of hands by a bishop are considered to be confirmed.
The Prayer Book rite for Confirmation includes forms for Reception and the Reaffirmation of Baptismal Vows. In some dioceses, those who have already made a mature Christian commitment in another denomination are recognized as members of the one holy catholic and apostolic church, and received into the fellowship of the Episcopal Church and the Anglican Communion. In other dioceses, those who have been sacramentally confirmed in the Roman Catholic or Orthodox churches are received and others are confirmed. Those who have returned from a time of religious inactivity to an active practice of faith may publicly reaffirm their baptismal vows. Others who have experienced a renewal of faith or desire to renew their Christian commitment may also reaffirm their baptismal vows. Reaffirmation may be repeated, depending on the pastoral needs of the person. Preparation for Confirmation/Reception/Reaffirmation should help the candidates discover the meaning of Christian commitment in their lives, and explore ways that their Christian commitment can be lived.
The Episcopal Church's theology of Confirmation has continued to evolve along with its understanding of baptism. Confirmation is no longer seen as the completion of Christian initiation, nor is Confirmation a prerequisite for receiving communion. Baptism is full initiation by water and the Holy Spirit into Christ's body the church (BCP, p. 298). Accordingly, Confirmation has been increasingly understood in terms of a mature, public reaffirmation of the Christian faith and the baptismal promises.
