In Confirmation, an adolescent or mature adult, after a period of instruction and preparation, makes a public affirmation of his or her responsibilities as a member of the body of Christ. The Bishop lays hands upon those being confirmed as the sacramental sign of the power of the Holy Spirit. Persons who have been baptized in other Christian communions but have not received the sacramental laying-on-of-hands of a Bishop and who now wish to live the Christian life in the Episcopal Church, may be presented for Confirmation. Any person who has been confirmed by a Bishop in another communion may be received by the Bishop of Chicago as a sign of welcome into the Episcopal fellowship of faith.
