As Egypt’s Islamists blame Christians for the ouster of Mohammed Morsi, anti-Christian violence has reached epidemic levels, with an estimated 82 churches across Egypt attacked and heavily damaged by Morsi supporters in a mere 48 hours.

Unfortunately, the persecution of Christians is nothing new in Egypt or other Muslim-majority countries. But thanks to the mainstream media, few Westerners understand the true scale or nature of the horrors involved.

As you read this, Christians around the world are being murdered, raped, plundered, abducted, forcibly converted to Islam, or otherwise oppressed by Muslims. Christians in Muslim-majority areas are some of the most vulnerable and horribly oppressed people on Earth; they live at the mercy of the mob and receive little or no protection from the police or other government institutions.

The reach of this silent tragedy is sweeping – a global religious genocide on “slow burn” with occasional conflagrations that make it into the mainstream media. There are an estimated 100 million persecuted Christians.

This massive crime is documented in shocking and painstaking detail in Raymond Ibrahim’s new book Crucified Again: Exposing Islam’s New War on Christians. The book is required reading for anyone who cares about religious freedom, human rights, and/or the survival of Christians in their ancestral lands.

In Crucified Again, Ibrahim methodically presents overwhelming evidence of Muslim persecution of Christians (documented with about 700 footnotes). His exhaustive, scholarly, and compelling study uses many news and historical sources, and statements by contemporary Muslim clerics. The evidentiary details are far too numerous to summarize here, but a few examples stand out.

Ibrahim explains the theological basis for Muslim persecution of Christians. He cites the Islamic belief that Koranic verses from later in Muhammad’s career abrogate contradictory verses from earlier. The hostile verses naming Christians “infidels” occur towards the end of his career, so they override any tolerance for Christians in earlier verses. Ibrahim writes: “The Koran’s final word on the fate of Christians and Jews is found in Koran 9:29 [where] Allah commands believers, [to fight them]…’until they pay the jizya with willing submission and feel themselves subdued.'”

Ibrahim cites the writing of renowned Muslim scholar Ibn Khaldun [1332-1406]:

[Jihad] is a religious duty, because of the universalism of the Muslim mission and the obligation to convert everybody to Islam either by persuasion or by force … The other religious groups did not have a universal mission, and the holy war was not a religious duty for them…But Islam is under obligation to gain power over other nations.

Ibrahim explains: “The Conditions of Omar…[details] exactly how [Christians and Jews] are to feel themselves subdued.” The laws applicable to “dhimmis” (non-Muslims treated as second-class citizens under Islamic hegemony) made life so miserable for Christians over the millennia that these rules gradually transformed thousands of miles of formerly Christian territory into what is today the “Arab world.” Ibrahim also highlights a tragic historical absurdity: many of the Muslims persecuting Christians today are themselves descendants of Christians who converted because of persecution.

Having established the theological basis for Muslim oppression of Christians, Ibrahim reviews the endless historical examples of these crimes. He cites one medieval Muslim historian reporting that “30,000 churches were burned or pillaged in Egypt and Syria alone” in just two years. During the Abbasid rule (in 936), “the Muslims in Jerusalem…burnt down the Church of the Resurrection [believed to be built atop the tomb of Christ].” Ibrahim notes the “1453 conquest of Constantinople by the Ottomans and the subsequent attack on…the Hagia Sophia and its transformation into a mosque.”

After reviewing the more notable examples from history, Ibrahim catalogs the extent to which such Muslim persecution of Christians continues today across the entire Muslim world, “from Afghanistan to Zanzibar” – regardless of race, ethnicity, culture, or language. Crucified Again details how these anti-Christian crimes are often incited by governments and/or religious leaders of Muslim countries. Ibrahim “broke news” in 2012 merely by translating into English that Saudi Arabia’s highest religious authority declared it “necessary to destroy all the churches” in the Arabian Peninsula. The shocking statement by Abdulaziz ibn Abdullah Al al-Sheikh, the Grand Mufti of Saudi Arabia, was widely reported by Arabic-language media, but the Western mainstream media avoided coverage of the outrage. As Ibrahim argues, the media willfully ignore such news because it contradicts their narrative that all Muslim violence is motivated by some socio-economic or political grievance.

But the West risks its own demise by ignoring four truths: 1) a hateful, absolutist ideology drives Islamist violence against non-Muslims, 2) sharia’s draconian penalties for apostasy and blasphemy maximize Muslim demographic growth because nobody can safely criticize or leave Islam (including those converted under duress), 3) sharia destroys the rights and freedoms cherished by the West, 4) sharia creates a Muslim monopoly on the marketplace of ideas – something antithetical to any free society. To survive, the West cannot let sharia laws take root in Muslim-majority communities of Europe and North America.
