First things first: Click play on the above YouTube. Now begin reading.

As you would expect, I have received quite a bit of email during the past 24 hours linked to my GetReligion post – "What brings Rome and Moscow together at last? Suffering churches in Syria, Iraq" – about the mainstream media coverage of the stunning announcement of a Feb. 12 meeting between Pope Francis and Patriarch Kirill of Moscow, the leader of the Orthodox Church of All Russia.

As you would expect, much of the press coverage has stressed what this all means, from a Roman Catholic and Western perspective.

This is understandable, since there are 1.2 billion Catholics in the world and Francis is the brightest star in the religion-news firmament at the moment. People who know their history, however, know that this meeting is also rooted in the life and work of Saint Pope John Paul II, who grew up in a Polish Catholic culture that shares so much with the churches of the East, spiritually and culturally.

I updated my piece yesterday to point readers toward a fine Crux think piece by the omnipresent (yes, I'll keep using that word) John L. Allen, Jr. Let me do that once again. Read it all, please. Near the end, there is this interesting comment concerning Pope Francis:

... His foreign policy priorities since his election have been largely congenial to Russia’s perceived interests. In September 2013, he joined forces with Vladimir Putin in successfully heading off a proposed Western military offensive in Syria to bring down the regime of Syrian President Bashar al-Assad.

Since then, Francis and Putin have met in the Vatican and found common ground on several matters, including the protection of Christians in the Middle East and the growing reemergence of Cuba in the community of nations.

This morning, my email contained another essay by a Catholic scribe that I stress is essential reading for those starting a research folder to prepare to cover the meeting in Havana. This is from Inside the Vatican and it is another eLetter from commentator Robert Moynihan.

This piece is simply packed with amazing details about events – some completely overlooked by the mainstream media – that have almost certainly, one after another, contributed to the logic of the Cuba meeting between Francis and Kirill.

It is certainly the most important story of the day for the world's Eastern Orthodox Christians. Yes, even bigger than the announcement – with the lengthy fast (no meat, no dairy) of Great Lent approaching – that Ben & Jerry's is poised to begin selling vegan ice cream.

I am referring to the announcement of a meeting between Pope Francis and Patriarch Kirill, the leader of the Orthodox Church in Russia.

Any meeting between the pope and the patriarch of all Russia would be historic, simply because the shepherds of Rome and Moscow have never met before. Hold that thought, because we will come back to it.

The big question, of course, is: Why are they meeting? What finally pushed the button to ease the tensions enough between these two churches for their leaders to meet?

In terms of the early news coverage, the answer depends on whether you are one of the few news consumers who will have a chance to read the Reuters report, being circulated by Religion News Service, or one of the many who see the Associated Press story that is, I believe, deeply flawed. Alas, the majority of news consumers will probably see a shortened version of the AP report and will be totally in the dark about the primary purpose of this historic meeting.

So here is the top of the Reuters report:

MOSCOW -- The patriarch of Russia’s Orthodox Church will take part in an historic first meeting with the Roman Catholic pontiff on Feb. 12 because of the need for a joint response to the persecution of Christians in the Middle East, the Orthodox Church said.

Senior Orthodox cleric Metropolitan Hilarion said that long-standing differences between the two churches remain, most notably a row over the status of the Uniate Church, in Ukraine. But he said these differences were being put aside so that Patriarch Kirill and Pope Francis could come together over persecution of Christians.
