Here is an explanation for the mandated terminology for official Ordinariate signs from a CSP Ordinariate priest sent in an e-mail response to the posting here: THE CATHOLIC CHURCH AND HER DISTINCT PARTS
I thought you might appreciate this feedback on your most recent posting. I'm pasting below a short bit from the US Ordinariate ministry manual regarding naming and public reference to Ordinariate groups:
So that the Ordinariate has common and uniform terminology for its communities and parishes in traditional and social media, as well as on websites and in other publications, Ordinariate groups will be referenced in this fashion:
a. For groups that are not-yet parishes: “Saint Augustine Church – a Catholic community of the Personal Ordinariate of the Chair of Saint Peter”.
b. For parishes and missions: “Saint Augustine Church – a Catholic parish of the Personal Ordinariate of the Chair of Saint Peter”.
c. If further explanation is needed: As an Ordinariate community/parish, we are fully Catholic and in union with the Holy Father, while retaining many elements of our Anglican patrimony. The Ordinariate of the Chair of St. Peter was established by Pope Benedict XVI on January 1, 2012 for communities like ours across the United States. (See www.usordinariate.org)
For an explanation as to why the proper and official title of the Catholic Church does not include "Roman" except in the Diocese of Rome, see the previous posting on official documents and names "The Catholic Church and her Distinct Parts".
