Within ROCOR.
Moscow and ROCOR are reuniting formally May 15th.
(see http://www.holyplacesandworldtravel.com/index.php?pilgrimages&reunification for some info on the details).
The process has been going on for years, and last year represenatives from all over ROCOR were sent to a meeting where they voted unanimously for reunification. Upon hearing the news some folks back home were less than pleased.
For a little history ROCOR was pretty well the church going remenants of the White Army folks who lost to the Soviets. Their children and grandchildren are the folks looking at this decision some happy to see the church restored in unity, some bitterly paranoid and against any sort of reunion.
