Along with the ordination of married former Episcopal priests, the Pastoral Provision of 1980 permitted the establishment of Anglican Use parishes in the United States and created a special missal using liturgical elements from the Anglican tradition. (Cf. Pope Paul VI, Sacerdotalis caelibatus, no. 42.) This special liturgy was subsequently approved in 1983 by the Vatican's Congregation for Divine Worship and the Committee for the Liturgy of the National Conference of Catholic Bishops. In 2003 it was published in book form as the "Book of Divine Worship" and the term "Anglican Use" liturgy was applied to it.
