Blessed Virgin on 25 March was from before the time of Bede until the 18th century New Year's Day in England. The Annunciation is called the "Annunciation of our Lady" in the 1662 Book of Common Prayer. Anglicans also celebrate in the Visitation of the Blessed Virgin on 31 May, though in some provinces the traditional date of 2 July is kept.

Historically, there has been enough common ground between Roman Catholics and Anglicans on Marian issues that in 2005, a joint statement called Mary: grace and hope in Christ was produced through ecumenical meetings of Anglicans and Roman Catholic theologians. This document, informally known as the "Seattle Statement", is not formally endorsed by either the Catholic Church or the Anglican Communion, but is viewed by its authors as the beginning of a joint understanding of Mary. Lutheran Despite Martin Luther's harsh polemics against his Roman Catholic opponents over issues concerning Mary and the saints, theologians appear to agree that Luther adhered to the Marian decrees of the ecumenical councils and dogmas of the church. He held
