In December 2017, the Security Service of Ukraine lifted classified top secret status of documents revealing that the NKVD of the USSR and its units were engaged in the selection of candidates for participation in the 1945 Local Council from the representatives of the clergy and the laity. NKVD demanded "to outline persons who have religious authority among the clergy and believers, and at the same time checked for civic or patriotic work". In the letter sent in September 1944, it was emphasized: "It is important to ensure that the number of nominated candidates is dominated by the agents of the NKBD, capable of holding the line that we need at the Council".
