Anastasy once again found himself in an area with military operations. In August 1917 he left Bessarabia for Moscow to participate in the All-Russian Council of 1917-1918. During the election of a new Patriarch of Moscow, his candidacy received 77 votes; he then participated in the preparation for the enthronement of Patriarch St. Tikhon of Moscow, which he described in his article "Election and Enthronement of His Holiness Patriarch Tikhon, his personality and work." Archbishop Anastasy was elected a member of the Holy Synod of Bishops. In October 1918, he departed from Moscow headed for Odessa with the hope of being able to return to Chişinău, which was under Romanian occupation. He was not able, however, to return to Bessarabia because of pressure from Romanian authorities to leave the Russian Church and enter into the jurisdiction of the Romanian Patriarchate.

The Congress made decisions about adopting the new calendar, allowing remarriage for clergy and married bishops, shortening services, eliminating fasts, and simplifying ecclesiastic robes. Archbishop Anastasius voiced his objections to such decisions, which he deemed uncanonical. Because the Ecumenical Patriarchate had forbidden the commemoration of Patriarch Tikhon at services in the Russian Orthodox parishes in the area and demanded that Archbishop Anastasius sever ties with the Synod Abroad of the ROCOR, he was forced to leave Constantinople for Bulgaria via France. In Bulgaria, he participated in the consecration of St. Alexander Nevsky Cathedral, and then departed for Serbia. In 1924, he was appointed as administrator of the Russian Ecclesiastical Mission in Jerusalem and departed for the Holy
