The order of Holy Mass for use by the Ordinariates erected under the auspices of Anglicanorum coetibus was approved and confirmed by the Apostolic See in May 2013. The missal has been published and implimented by all the Ordinariates in December 2015. This provision of the Order of Holy Mass represents a substantial revision of the Book of Divine Worship, Holy Eucharist Rite One, as developed by the Congregation for the Doctrine of the Faith and the Congregation for Divine Worship in consultation with the Interdicasterial Commission Anglicanane traditiones. This Order of Mass was designed pursuant to the provisions of the Apostolic Constitution Anglicanorum coetibus for a rite of Holy Mass to be fashioned “according to the liturgical books proper to the Anglican tradition” insofar as compatible with Catholic doctrine and receiving the approval of the Holy See. Accordingly, this order was devised in light of the following principles and objectives:
(a) to preserve in the Catholic Church the worthily Anglican liturgical patrimony, understood as that which has nourished the Catholic faith throughout the history of the Anglican tradition and prompted aspirations towards ecclesial unity;
(b) to maintain for catholic worship such features and elements that are representative of the historic Anglican books of Common Prayer (in the first place) and the Anglican missals (in the second place), in conformity with Catholic doctrinal and liturgical norms;
(c) to provide an Order of Mass at once distinctively and traditionally Anglican in character, content and structure, whilst also being clearly and recognizable a form of the Roman Rite, in both its modern and traditional expressions, safeguarding thereby the substantial unity of the Roman Rite;
(d) to combine, consolidate, and harmonize wherever possible the diversity of Anglican liturgical usage for the sake of assuring the continuity, integrity, and pastoral utility of the rite for the Ordinariates in England and Wales, the United States, Canada, and Australia;
(e) to minimize the number of options, except where clearly justified by the need for pastoral flexibility in respecting the various constituencies coming together in Catholic unity, to preserve worthy Anglican patrimony, or to suit the dignity of the celebration according to the quality of the day or season;
(f) to offer an instrument for the sanctification of the faithful who come to the Catholic Church from the Anglican tradition whilst promoting their unity with one another, with their fellow Catholics in the wider Church, and with the See of Peter.
