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 is the oldest Anglican devotional society and was founded in 1862 by Thomas Thellusson Carter during the Oxford Movement in the Church of England and has worked to promote the Mass as the weekly main service, 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". The confraternity as now constituted represents the amalgamation of two earlier societies, namely, the Society of the Blessed Sacrament, founded in 1860, and the Confraternity of the Blessed Sacrament, founded in 1862. The two societies united on 26 February 1867.
Associates and priests-associate (the constitution differentiates between the two, but the requirements are identical) of the Confraternity of the Blessed Sacrament strive to promote reverence for Jesus in the Holy Eucharist through the witness of their lives, words, prayers and teaching. They pray for one another at Mass and before the Blessed Sacrament and make use of the Sacrament of Reconciliation.
The confraternity consists of autonomous provinces, of which there are currently two - the English (and original) CBS and the American CBS - each led by a superior-general and administered by a secretary-general and treasurer-general. Additionally there are semi-autonomous branches of CBS in both Canada and Australia, though currently neither has the numerical strength to become a fully autonomous province, and so they remain part of the English CBS. The English CBS is also active in Sweden, Wales and the Channel Islands. Currently lacking structure, there are fledgling CBS movements in parts of Africa.
