Glasnost and evidence of collaboration with the KGB

Beginning in the late 1980s, under Mikhail Gorbachev, the new political and social freedoms resulted in the return of many church buildings to the church, so they could be restored by local parishioners. A pivotal point in the history of the Russian Orthodox Church came in 1988, the millennial anniversary of the Christianization of Kievan Rus'. Throughout the summer of that year, major government-supported celebrations took place in Moscow and other cities; many older churches and some monasteries were reopened. An implicit ban on religious propaganda on state TV was finally lifted. For the first time in the history of the Soviet Union, people could watch live transmissions of church services on television.

Gleb Yakunin, a critic of the Moscow Patriarchate who was one of those who briefly gained access to the KGB 's archives in the early 1990s, argued that the Moscow Patriarchate was "practically a subsidiary, a sister company of the KGB". Critics charge that the archives showed the extent of active participation of the top ROC hierarchs in the KGB efforts overseas. George Trofimoff, the highest-ranking US military officer ever indicted for, and convicted of, espionage by the United States and sentenced to life imprisonment on 27 September 2001, had been "recruited into the service of the KGB" by Igor Susemihl (a.k.a. Zuzemihl), a bishop in the Russian Orthodox Church (subsequently, a high-ranking hierarch—the ROC Metropolitan Iriney of Vienna, who died in July 1999).

Konstanin Kharchev, former chairman of the Soviet Council on Religious Affairs, explained: "Not a single candidate for the office of bishop or any other high-ranking office, much less a member of the Holy Synod, went through without confirmation by the Central Committee of the CPSU and the KGB ". Professor Nathaniel Davis points out: "If the bishops wished to defend their people and survive in office, they had to collaborate to some degree with the KGB, with the commissioners of the Council for Religious Affairs, and with other party and governmental authorities". Patriarch Alexy II, acknowledged that compromises were made with the Soviet government by bishops of the Moscow Patriarchate, himself included, and he publicly repented for these compromises.
