On October 25–28, 1990, Rukh held its second congress and declared that its principal goal was the "renewal of independent statehood for Ukraine". On October 28 UAOC faithful, supported by Ukrainian Catholics, demonstrated near St. Sophia’s Cathedral as newly elected Russian Orthodox Church Patriarch Aleksei and Metropolitan Filaret celebrated liturgy at the shrine. On November 1, the leaders of the Ukrainian Greek Catholic Church and of the Ukrainian Autocephalous Orthodox Church, respectively, Metropolitan Volodymyr Sterniuk and Patriarch Mstyslav, met in Lviv during anniversary commemorations of the 1918 proclamation of the Western Ukrainian National Republic.
