With some news events, not much happens but the atmosphere is so striking that it’s worth mentioning all the same. That was the case in Moscow this week as Cardinal Walter Kasper, head of the Vatican’s Pontifical Council for Christian Unity, met Russian Orthodox Patriarch Alexiy II.

Though this was an unofficial visit, the patriarch and the cardinal both took care to use language noticeable for its friendly, accommodating and even warm tone in their greetings - a continuation of what is seen as a “thaw” and “emerging cooperation” between the two churches.

“I am convinced of the necessity in an Orthodox-Catholic dialogue, based on the coincidence of our positions on many of the issues facing the Christian world today,” Alexiy told Kasper. “I believe (your) interest in the life and traditions of the (Orthodox) Church will turn out to be important between our two Churches.”

For his part, Kasper returned the greeting in kind: “We have met more than once now, but each time I meet with you I do so with great happiness. And I hope this meeting will enable further development in our relations, contacts and cooperation.”

He also brought a personal message from Pope Benedict who praised the “growing closeness between us, accompanied by the shared desire to promote authentic Christian values and to witness to our Lord in ever deeper communion.”

In private the two men discussed issues of religious education at Catholic orphanages for those baptised Russian Orthodox and the spread of the Uniate faith in western Ukraine, an area seen by Moscow as within Russian Orthodoxy’s canonical territory.

The elephant in the room, which the two men did not discuss in front of reporters, was whether the formerly frosty relations between the two churches had thawed enough to facilitate a future meeting between Alexiy and Benedict, something the Pope is actively seeking. Only last October, the Russians walked out of a theological dialogue meeting with the Catholic Church in Ravenna, Italy in protest over a doctrinal issue.

“Nothing concrete was said about this, but there was a confirmation on principle that a meeting is possible,” a spokesman for the Russian Orthodox Church told reporters after the meeting. “But, as His Holiness the Patriarch said, this kind of meeting has to be well planned so that it isn’t just a photo-opportunity.”

While in Russia, Kasper also toured Orthodox dioceses in Nizhny Novgorod, Smolensk and Kazan to pray at icons there before stopping in Moscow, a gesture seen as a welcome sign of respect for the Russian church.

Jews are returning to Russia. For as long as anyone alive can remember, the flow was mostly in the other direction. But Amie Ferris-Rotman and Conor Sweeney in our Moscow bureau have found a return wave, despite a persistent anti-Semitism there:

Around one million Jews fled during the Soviet era and the post-communist chaos. Those returning now from Israel, the United States and Europe hope to use their new skills and old knowledge to do business.

“Now there are services here, like in New York and Paris, but the lifestyle is more interesting than in either of them — it’s easy to understand why thousands are coming back,” said Yevgeny Satanovsky, president of the Russian Jewish Congress.

Hard statistics on Jews returning to Russia do not exist, said Satanovsky, but anecdotal evidence is there. He estimates 80,000-120,000 Russian Jews have returned, plus many more who originated in other Soviet republics.
