Relations with the Russian Orthodox church have been difficult for nearly a millennium, and attempts at re-establishing Catholicism have met with opposition. Pope John Paul II expressed a desire to visit Russia, but the Russian Orthodox Church resisted. In April 2002, Bishop Jerry Mazur of Eastern Siberia was stripped of his visa, forcing the appointment of a new bishop for that diocese. In 2002, five foreign Catholic priests were denied visas to return to Russia, construction of a new cathedral was blocked in Pskov, and a church in southern Russia was shot at. On December 25, 2005, Russian Orthodox activists planned to picket outside of Moscow's Catholic Cathedral, but the picket was cancelled. Despite easing of relations with the election of Pope Benedict XVI, there remain issues such as the readiness of the police to protect Catholics and other minorities from persecution.
