→1970: Autocephaly for the OCA: add link
At the same time that the [[Church of Russia]] was about to declare the autocephaly of the Metropolia, it announced that it was going to begin communing [[Roman Catholic Church|Roman Catholics]]. Vladimir Moss, a former ROCOR layman, writes in his ''[http://uk.geocities.com/guildfordian2002/History/OrthodoxChurch20thCenturyP1.htm The Orthodox Church in the Twentieth Century]'':
:...in October, 1969, Metropolitan Nicodemus gave communion to Catholic students in the Russicum in Rome. This was followed, on December 16, by a decision of the Russian Holy Synod to give permission to Orthodox clergy to administer the sacraments to Old Believers and Catholics... The decision of the Moscow Patriarchate to give communion to Catholics put the other Russian jurisdiction in North America, the Metropolia, into a difficult position; for in the early 1960s the Metropolia (a body in schism from the ROCA since 1946) had been, through Fathers John Meyendorff and Alexander Schmemann, among the most conservative participants in the ecumenical movement.[http://uk.geocities.com/guildfordian2002/History/OrthodoxChurch20thCenturyP3.htm]
He further writes that the autocephaly about to be received from Moscow was part of a secret deal between the Metropolia and Moscow, and that the price of the Metropolia's autocephaly was to be the newly revitalized [[Church of Japan]]:
As the ROCOR protested the action of the Moscow Patriarchate, the OCA began distributing reports regarding the ROCOR denying that the Metropolia had ever been a part of it, that the ROCOR was "uncanonical," and that it should be avoided by OCA faithful. The OCA was joined in this effort by Abp. [[Iakovos (Coucouzis) of America|Iakovos (Coucouzis)]] of the [[Greek Orthodox Archdiocese of America|Greek Archdiocese]], whose [[ecumenism|ecumenical]] activities in the 1960s and 1970s had seen the departure of some of his scandalized clergy to the Church Abroad, including the whole of [[Holy Transfiguration Monastery (Brookline, Massachusetts)|Holy Transfiguration Monastery]] in Brookline, Massachusetts. Up to that point, the Greek Archdiocese had been in [[full communion]] with the ROCOR.

==Early 1980s: The OCA Calendar Schism==
In 1982, Bishop [[Herman (Swaiko) of Washington and New York|Herman (Swaiko) of Philadelphia]], the OCA's bishop for Eastern Pennsylvania, decreed that all of his parishes would begin using the [[Revised Julian Calendar]]. Some were already using it, but others had been using the [[Julian Calendar]] steadily up to that point.
