Morning Prayer (also Matins or Mattins), is one of the two main Daily Offices in Anglican churches, prescribed in the various editions of the Book of Common Prayer and other Anglican liturgical texts. Like Evening Prayer (and in contrast to the Eucharist), it may be led by a layperson and is recited by some Anglicans daily in private (clergy in many Anglican jurisdictions are required to do so).
In its classic form, in the 1662 version of the Prayer Book, the Morning Prayer is essentially unchanged from Archbishop Thomas Cranmer’s Second Prayer Book of Edward VI, published in 1552. It draws on the monastic offices of Matins, Lauds and Prime, beginning with opening versicles and responses, continuing with the invitatory "Venite" (Psalm 95), the "Te Deum" and "Benedictus", interspersed with Bible readings, as well as recitation of the Apostles’ Creed, and ending with closing versicles adapted from the Breviary. The Prayer Book lectionary provides for a virtually complete reading of the Bible in the course of a year.
The usual practice in medieval parish worship was for the congregation to attend the office of Matins, followed by the Latin Mass according to the Roman Rite, followed by the Litany of the Saints, sung in procession. Following the Reformation, the usual Sunday Service followed a similar pattern, but with the English Litany said between Morning Prayer and Holy Communion. On Sundays when there was no celebration of Communion (i.e. most of them), only the ante-Communion would be said. Even so, — and taking into account the legal requirement to read one from the specified set of printed Homilies — the post-Reformation service lasted more than twice as long as its pre-Reformation equivalent. Historically, Morning Prayer was the main Sunday morning service on most Sundays in all Anglican parishes, with Holy Communion being celebrated after Morning or Evening Prayer (typically once a month, on the first Sunday). In the twentieth century, Holy Communion became the main Sunday morning service once or twice per month. With the revival of the Eucharist as the principal Sunday service during the second half of the twentieth century, Morning Prayer has been the principal Sunday service less frequently.
