From the Catechism of the 1979 Book of Common Prayer (BCP) page 860
Q. What is Confirmation? A. Confirmation is the rite in which we express a mature commitment to Christ, and receive strength from the Holy Spirit through prayer and the laying on of hands by a bishop.
Q. What is required of those to be confirmed? A. It is required of those to be confirmed that they have been baptized, are sufficiently instructed in the Christian Faith, are penitent for their sins, and are ready to affirm their confession of Jesus Christ as Savior and Lord.
From the introduction to the Rite for Confirmation, BCP page 412
In the course of their Christian development, those baptized at an early age are expected, when they are ready and have been duly prepared, to make a mature public affirmation of their faith and commitment to the responsibilities of their Baptism and to receive the laying on of hands by the bishop.
Those baptized as adults, unless baptized with laying on of hands by a bishop, are also expected to make a public affirmation of their faith and commitment to the responsibilities of their Baptism in the presence of a bishop and to receive the laying on of hands. BCP p. 412
Confirmation at Saint Thomas Church is held on the Sunday that the Bishop makes his annual visitation to the parish, usually in May. To be confirmed here, a child should be enrolled in our Sunday School, and must register for and attend confirmation classes. These classes usually begin at the beginning of the calendar year. The classes provide a basic catechesis in the Christian faith.
