In 2020, the first of two editions of "" was published. While the "North American Edition" was the first Divine Office introduced in the Personal Ordinariate of the Chair of Saint Peter, the "Commonwealth Edition" succeeded the previous "Customary" for the Personal Ordinariates of Our Lady of Walsingham and Our Lady of the Southern Cross. The "North American Edition" more closely follows the American 1928, American 1979, and Canadian 1962 prayer books, while the "Commonwealth Edition" more closely follows the precedents set by the Church of England's 1549 and 1662 "Book of Common Prayer".
