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".
