Morning Prayer (also Mattins or Matins), in the various editions of the Book of Common Prayer and other Anglican liturgical texts, was, until the last quarter of the twentieth century, the main Sunday morning service on most Sundays in all but the most high church Anglican parishes, with Holy Communion being the main Sunday morning service once or twice per month, or rarely, quarterly. Like Evensong (and in contrast to the Eucharist), it can be led by a layperson, and is recited by some devout Anglicans daily in private (clergy in many Anglican jurisdictions are required to do so).
The Eucharist, Mass or Holy Communion
The Eucharist is the rite that Christians perform in fulfillment of the instruction (reported in 1 Corinthians 11:24–25) that Jesus gave to do in his memory. It is a sacramental or memorial reenactment of what he did at his Last Supper in giving his disciples bread, saying “This is my body,” and the cup, saying “This is my blood.”
