confirmation

n. formal approval; proof; verification; coming of age ceremony (Christianity, Judaism)

See Reform Judaism article about its Confirmation ceremony. Confirmation is a rite in many Christian Churches.Roman Catholics, Eastern Orthodox, Oriental Orthodox Churches, and Anglicans, view it as a sacrament, which in the East is conferred on infants immediately after baptism, but in the West is usually administered later at the age of reason or in early adolescence.According to canon law for the Latin or Western Catholic Church, the sacrament is to be conferred on the faithful at about the age of discretion (generally taken to be about 7), unless the Episcopal Conference has decided on a different age, or there is danger of death or, in the judgement of the minister, a grave reason suggests otherwise (canon 891 of the Code of Canon Law). The number of Episcopal Conferences that have set a later age, usually between 14 and 16 years of age, has diminished in recent decades, and even in those countries a bishop may not refuse to confer the sacrament on younger children who request it, provided they are baptized, have the use of reason, are suitably instructed and are properly disposed and able to renew the baptismal promises (letter of the Congregation for Divine Worship and the Discipline of the Sacraments published in its 1999 bulletin, pages 537-540).
