The Seal of the Confessional is a principle within Anglicanism which protects the words spoken during confession. Confession has certain censures on disclosure as there is an understanding among the clergy that there is an inviolable confidence between the individual priest and the penitent. This principle should not be confused with the rarer practice of lay confession, nor with the public confession of sins which is an element of most eucharistic liturgies throughout the Anglican Communion. The "Seal of the Confessional" refers specifically to the private confession of sins by an individual, in the presence of a priest, the form of which is regulated by the 1662 Book of Common Prayer and later liturgical sources.
