This number is not merely exaggerated. It is profoundly misleading, historically indefensible, and morally reckless.
It is variously an impossibility in demographic terms, a collapse of historical proportion, and also a tragic disservice to the memory of those who have truly suffered persecution throughout the ages—Catholic, Protestant, Orthodox, Adventist, and others, including non-Christian victims of religious violence such as the Jews and most recently the Yazidis killed by ISIS in Sinjar in Iraq in 2016 and the Rohingya Muslims killed by Theravada Buddhists in Burma.*
To understand how wildly out of proportion this number is, consider that:
- The entire population of Europe during the height of the Church’s institutional influence (say, 1300 AD) was fewer than 80 million.
- The combined global death tolls of World War I and World War II—our two deadliest wars—amount to a maximum of 125 million people.
- The best estimates from qualified historians for the Spanish Inquisition—perhaps the most cited incident in these accusations—are around 3,000 to 5,000 deaths over several centuries. Not 125 million. Not 1 million. Not even 10,000.
That number—3,000 to 5,000—isn’t pleasant. Every unjust death is a tragedy. But to inflate that by four orders of magnitude and make it the cornerstone of anti-Catholic polemic is irresponsible in the extreme.
Even if one were to add the deaths from the Crusades (perhaps 1–3 million), the French Wars of Religion, the Thirty Years’ War (which involved Protestants and Catholics alike), and all ecclesiastically-adjacent colonial violence (much of which was carried out by states, not churches), we still do not arrive at anything close to such a fantastical total.
There are no historical documents, no demographic records, no papal decrees, no annals, no serious scholarly works—none—that even attempt to make such a claim. The figure of 125 million comes not from history but from fringe literature, often passed along in sensationalist media, anti-Catholic tracts, or uncritical internet memes. The fact that no one ever seems able to itemize these alleged deaths should be telling.
What Scripture has to say about reckless speech is not ambiguous:
“Thou shalt not bear false witness against thy neighbor.” — Exodus 20:16
“The one who conceals hatred has lying lips, and whoever utters slander is a fool.” — Proverbs 10:18
“But I tell you that every careless word that people speak, they shall give an accounting for it in the day of judgment.” — Matthew 12:36
A Christian has every right to disagree with Catholic doctrine. That is a matter of conscience and conviction. But we are forbidden, under pain of judgment, to traffic in grotesque exaggerations designed to provoke hatred.
The Roman Catholic Church has made mistakes. So have Protestants, Orthodox Christians and even Adventists. So have kings, and councils, and empires, and armies, and every other human institution. The pursuit of truth demands that we neither minimize real evil nor invent imaginary ones.
* Buddhism might actually have a much higher body count than Roman Catholicism when we consider the death of all Christians in China, Mongolia and Tibet during a time coinciding with Tamerlane’s persecution of the Church of the East, and while Tamerlane did have influence in Mongolia, as a half-Mongolian Turk, his influence in China was much less, and non-existent in Tibet, so the only way the Church of the East could have been extirpated from the Far East involved, at a minimum, substantial Buddhist complicity. We also have the case of the ongoing persecutions of the Rohingya Muslims in Burma and of the Hindu minority in Bhutan, by the Drukpa “Red Hat” Buddhist majority.
