The classic Anglican understanding of the Eucharist (also known as the Mass, Holy Communion, the Lord’s Supper) is expressed in the invitation to communion derived from the 1552 Prayer Book and written by Thomas Cranmer:
Draw near with faith. Receive the body of our Lord Jesus Christ which he gave for you and his blood which he shed for you. Eat and drink in remembrance that Christ died for you, and feed on him in your hearts by faith with thanksgiving.
Over two Sundays in some years, instead of preaching a sermon, the clergy may slow down the Eucharist so that we can ponder what it is we do at Holy Communion and why. On those Sundays the Order of Worship (reproduced here) includes marginal notes.
