In Christianity, Confirmation is seen as the sealing of Christianity created in Baptism. Those being confirmed are known as confirmands. In some denominations, such as the Anglican Communion and Methodist Churches, confirmation bestows full membership in a local congregation upon the recipient. In others, such as the Roman Catholic Church, Confirmation "renders the bond with the Church more perfect", because, while a baptized person is already a member, "reception of the sacrament of Confirmation is necessary for the completion of baptismal grace".
Roman Catholics, Eastern Orthodox, Oriental Orthodox, and Latter-Day Saint Churches view Confirmation as a sacrament. In the East it is conferred immediately after baptism. In the West, this practice is usually followed when adults are baptized, but in the case of infants not in danger of death it is administered, ordinarily by a bishop, only when the child reaches the age of reason or early adolescence. Among those Catholics who practice teen-aged Confirmation, the practice may be perceived, secondarily, as a "coming of age" rite.
Latter-Day Saint Churches do not practice infant baptism, but baptize only after the "age of accountability" is reached. Confirmation occurs either immediately following Baptism, or on the following Sunday. The Baptism is not considered complete or fully efficacious until Confirmation is received.
In traditional Protestant denominations, such as the Anglican, Lutheran, Methodist and Reformed Churches, Confirmation is a rite that often includes a profession of faith by an already baptized person. It is also required by most Protestant denominations for full membership in the respective Church, in particular for traditional Protestant churches, in which it is also recognized secondarily as a coming of age ceremony.
Confirmation is not practiced in Baptist, Anabaptist and other groups that teach believer's baptism. Thus, the sacrament or rite of Confirmation is administered to those being received from those aforementioned groups, in addition to those converts from non-Christian religions.
There is an analogous ceremony also called Confirmation in reform Judaism. It was created in the 1800s by Israel Jacobson.
