The Confraternity of the Blessed Sacrament (CBS), officially the Confraternity of the Blessed Sacrament of the Body and Blood of Christ, is a devotional society in the Anglican Communion dedicated to venerating the Real Presence of Christ in the Eucharist. It has worked to promote the Mass as the main Sunday service in churches, regular confession, and the Eucharistic fast. The society's motto is Adoremus in aeternum sanctissimum sacramentum, or in English, "Let us forever adore the Most Blessed Sacrament".
It is the oldest Anglican devotional society. In its present form it resulted from the amalgamation on 26 February 1867, of two older societies: the Society of the Blessed Sacrament, founded in 1860, and the Confraternity of the Blessed Sacrament, founded in 1862 by Thomas Thellusson Carter during the Oxford Movement in the Church of England. Members are known as associates.
