I'm no expert on Christians in the Middle East, but this strikes me as a powerful, important read.

It's an in-depth report from the Wall Street Journal on the "epochal shift" of Christians from the Middle East.

TANTA, Egypt — Like the Jews before them, Christians are fleeing the Middle East, emptying what was once one of the world’s most-diverse regions of its ancient religions.

They’re being driven away not only by Islamic State, but by governments the U.S. counts as allies in the fight against extremism.

When suicide bomb attacks ripped through two separate Palm Sunday services in Egypt last month, parishioners responded with rage at Islamic State, which claimed the blasts, and at Egyptian state security.

Government forces assigned to the Mar Girgis church in Tanta, north of Cairo, neglected to fix a faulty metal detector at the entrance after church guards found a bomb on the grounds just a week before. The double bombing killed at least 45 people, and came despite promises from the Egyptian government to protect its Christian minority.

This story is packed with hard data and gripping detail such as this:

In northern Iraq, blue and white charter buses crisscross neighborhoods of recently liberated Mosul, returning Muslim families displaced by Islamic State. They drive through Christian areas without stopping. For the first time in nearly two millennia, Iraq’s second-largest city, once a melting pot of ancient religions, lacks a Christian population to speak of.

The Al-Aswad family, a clan of masons who built the city’s houses, churches and mosques and trace their lineage back to the 19th century, vow never to return. They’ve opted to live in the rat-infested refugee camps of Erbil in northern Iraq, where they await updates on their asylum application to Australia.

A Christian charity has given them a small apartment until June, at which point they will have to return to the refugee camps to live in a converted cargo shipping container.

“We call it the cemetery,” said Raghd Al-Aswad, describing how the cargo containers are covered with dark blue tarps to protect against the rain. “It looks like dead bodies stacked side by side with a giant hospital sheet on top of them.”

Besides the words, the WSJ offers an eye-catching visual presentation that includes compelling photos and a graphic highlighting individual countries' declines in Christian population.

It's serious, world-class journalism on a subject of global significance.

By all means, read it.
