|"...the only group between the English Channel and Hawaii..."|
Any group can be placed on the map, just email Mr. Schaetzel and provide "1. Name of your group, 2. Address where your group primarily meets, 3. phone number for your group, (and) 4. email and webpage for your group if applicable."
So, go and check it out if you want to visit a local group. If you attend any service, remember that some of these groups are now in formal full communion with the Vatican while others have not completed the process and are still formally outside the Roman Catholic Church.
Some bloggers have taken the information provided by the map and did some number crunching. Back in February 2011, Br. Stephen Treat, O.Cist. wrote on The AngloCatholic blog that, based on the then-current numbers, "an American Ordinariate—in a worst case scenario—(would be) larger than 21 of the domestic dioceses of The Episcopal Church (of the United States)" and that, "If an American Ordinariate were to grow to an (Average Sunday Attendance) of 5000, it would be either larger than or roughly the same size as 59 of the domestic dioceses of The Episcopal Church." He concluded saying "These are still very small numbers in Catholic terms, but, in Anglican terms, I would say that an American Ordinariate looks quite credible."
Numbers are always tricky and the success or failure of any spiritual endeavor should not be measured in statistics, but I find it interesting to think about nonetheless. Some say that the Ordinariates will be too small to matter or to be sustainable. Clearly even back in February neither was the case.
I did a quick calculation. As of today, August 22, 2011, 63 groups are listed in the United States. When Br. Treat did his calculations above there were 36 groups plotted on the map.
