Anglican doctrine concerning the eucharist is contained in "Article XXVIII - Of the Lord's Supper" and "XXIX - Of the Wicked which eat not the Body of Christ" of the Thirty-Nine Articles. The Catechism of the Church of England, the foundational church of the Anglican Communion, is found in the Book of Common Prayer and states that, as with other sacraments, the eucharist is "an outward and visible sign of an inward and spiritual grace given unto us, ordained by Christ himself, as a means whereby we receive the same, and a pledge to assure us thereof." The outward sign, in this instance, is the bread and wine; and the thing signified is the body and blood of Christ.
