 Ex-UGCC priest Havryil Kostelnyk (who later died under dubious circumstances) was forced or convinced to preside over this Lviv Sobor of 1946, probably due to blackmailing by the Soviet NKVD and other secret services.Ironically, as all the bishops of the UGCC were at this point either in prison or exile, no bishops of the UGCC were involved, making the supposed synod or sobor canonically illegitimate by the official canons of both Orthodox and Catholic Churches alike.Whilst officially all of the church property was transferred to the Russian Orthodox Church under the Moscow Patriarchate, some Ukrainian Greek Catholic clergy went underground.
