The Pentecost massacre in Nigeria was the latest chapter in an old, old news story

The massacre occurred during a Sunday Mass, but it wasn't an ordinary Sunday -- this was the great feast of Pentecost, which marks the end of the Easter season.

What's more, the gunmen didn't strike in tense northern Nigeria, where Christian communities are isolated in a majority-Muslim region. This 30-minute attack was inside St. Francis Catholic Church, located in the safer southwestern state of Ondo.

While 40 worshippers were confirmed dead, including five children, the number was almost certainly higher since many families buried their dead privately. Another 100 were wounded.

The scope of this attack was "unique," especially in southern Nigeria, but "this violence … was not unique in its occurrence," stressed Stephen Rasche, senior fellow at the independent Religious Freedom Institute in Washington, D.C. "These types of murders are taking place weekly, almost daily, in Nigeria -- murders of innocent Christians, being gunned down, slaughtered indiscriminately, throughout the north and, increasingly, into the central part of Nigeria and into the south."

Human-rights activists are trying to document the bloodshed. According to the nondenominational watchdog group Open Doors, the 4,650 Christians killed in Nigeria during 2021 accounted for 80% of such deaths worldwide -- nearly 13 per day. Nigeria's Christian death toll has topped 60,000 over the past two decades.

Nevertheless, this year's International Religious Freedom Report from the U.S. State Department said the "Secretary of State determined that Nigeria did not meet the criteria to be designated as a Country of Particular Concern for engaging in or tolerating particularly severe violations of religious freedom or as a Special Watch List country for engaging in or tolerating severe violations of religious freedom."

It's understandable that news reports about Nigeria have faded, in part because of Russia's invasion of Ukraine and pressing global economic issues, said Rasche, who visited Nigerian churches during this Holy Week and Easter.

Also, many Western leaders view atrocities in Nigeria as clashes between Christian farmers and Muslim cattle herders, with climate-change issues erasing safety zones between these groups.

Early in the Iraq war, Rep. Mike Pence of Indiana took part in a congressional fact-finding trip to meet with U.S. troops.

Some of the lessons he learned during his first trip to that troubled land had more to do with religion than with warfare. While meeting with local officials, for example, Pence watched the local imam rush to embrace a friend -- the Catholic bishop in southern Iraq. A translator said the imam thanked the bishop for staying in touch after the recent death of his mother.

That was enlightening, said Vice President Pence, during the recent "Help the Persecuted" summit in Washington, D.C. But he also learned a crucial fact that day.

"I turned to the diplomatic aide who was with me," Pence recalled, "and said, 'So there's a Catholic church in al-Basrah?' And he said, 'Yes, yes there is.' And I said, 'How long has there been a Catholic church in al-Basrah?' And he said, 'About 1,500 years.' "

That's a sobering fact, since Iraq's Christian population has fallen 80 percent since that 2004 meeting, said Pence. The Christian population of Syria has fallen 50 percent in the past six years.

"As you all know, no people of faith face greater hostility or hatred than followers of Christ," said the vice president. "In more than 100 nations, spread to every corner of the world … over 245 million Christians confront intimidation, imprisonment, forced conversion, abuse, assault or worse."

Nohere is this onslaught more evident than in the "ancient land where Christianity was born," he added. "In Egypt we see the bombing of churches during Palm Sunday celebrations. In Iraq we see monasteries demolished, priests and monks beheaded and the two-millennia-old Christian tradition in Mosul clinging for survival. In Syria, we see ancient communities burned to the ground and believers tortured for confessing the name of Christ. … Christianity now faces an exodus in the Middle East unrivaled since the days of Moses."

Pence has made similar remarks before, but these statements rarely gain traction outside the world of Christian media. The problem is that the words "religious persecution" -- especially when linked to suffering Christians -- remain controversial among some public officials and journalists.

In Britain, for example, immigration officials ruled against the asylum claim of an Iranian national who had converted to Christianity. Here's what made headlines: The Home Office backed this action with claims that Christianity is not a religion of peace, quoting Leviticus 26:7 ("Ye shall chase your enemies, and they shall fall before you by the sword") and the words of Jesus in Matthew 10:24 ("Do not think that I have come to bring peace on earth; I have not come to bring peace, but a sword").

Meanwhile, the Christian Broadcasting Network and other conservative groups have noted, in recent weeks, the deaths of an estimated 120 Christians in central Nigeria.
