From National Catholic Register-
Benedict XVI gave a tremendous gift to the English-speaking world in 2009, when he finally realized a dream centuries in the making, and established a permanent canonical home for groups from the Anglican tradition seeking to enter the Catholic Church with the apostolic constitution Anglicanorum Coetibus.
Today, the Catholic Church has three Personal Ordinariates — informally known as the “Anglican Ordinariates” — that preserve the Anglican patrimony in their Catholic parishes, communities, and religious orders. These Personal Ordinariates have the only English form of the Roman Missal, promulgated by Pope Francis, called Divine Worship — an actual English form, not an English translation of the Latin Mass — written in traditional, poetic “Prayer Book” English. Each Personal Ordinariate covers a region of the globe (Oceania, the United Kingdom, and North America) and is headed by a bishop or ordinary who falls directly under the jurisdiction of the Congregation for the Doctrine of the Faith.
But how did the Vatican determine the solution for corporate unification with the Catholic Church had to be this structure called a “Personal Ordinariate?”
