I found the
site of the organisations which calls itself the Brotherhood of Holy Cross (Rus: Братствo Креста Господня).
They claim to have Primates of Churches of Constantinople, Romania, Cyprus, Jerusalem, EP's Russian Exarchate, EP's Estonian Church and Romanian's Moldavian Church as well as Grand Masters of Maltan and Teuton Orders and even Augusto Pinochet.
Who are they? Are they for real? What do they want?
