I spotted the other day a nice article about the Confraternities of Catholic Clergy that now exist in the United States, Australia, and Britain. The confraternity in each country is entirely independent of the others, but each certainly shares similar aims.
In January 2010, the Confraternities of the U.S. and Australia met for a joint conference in Rome, which was a wonderful experience to be part of. Another joint conference in Rome is planned for 2015. Clergy from Britain who were present in Rome in 2010 have since formed their own Confraternity. I have heard also that moves are afoot to establish a Confraternity in Ireland.
