Regarding chapter 12 in Stark’s Triumph of Christianity, I find his opening assertions remarkable.

In chapter 9, on assessing growth, he points out that through Constantine’s conversion, to about 350 CE, we have sufficient reliable data to say that a simple logarithmic growth model of 3.4% per year holds. However, he points out that it had to slow rapidly after that.

Here is why:

Year Christians in Roman Empire
40 1,000 Thousand
50 1,397
100 7,434
109 10,044 Ten Thousand
150 39,560
178 100,887 Hundred Thousand
180 107,864
200 210,517
247 1,013,331 Million
250 1,120,245
300 5,961,288
312 8,904,029 (Milvian Bridge)
316 10,178,146 Ten Million
350 31,722,471 (around half the empire)
385 102,231,768 Hundred Million
454 1,026,840,633 Billion
523 10,313,835,968 Ten Billion

See the problem?

Dr. Stark presents the table above in chapter 9, and I’ve added some numbers for clarity.

I recalculated the numbers by dropping them in a spreadsheet, adding 3.4% per year, one year at a time. My numbers matched his. It is clear that the 3.4% growth rate dropped off rapidly after Christians became the majority. Otherwise, there would have been more Christians than living people. I’m sure various factors ensured it slowed rapidly. Probably the largest factor was that there were simply fewer non-Christians. If everyone you know is Christian, you can’t convert any of them. Probably official sanction slowed the growth too, simply because of loss of zeal.

Regardless, the growth seems astonishing when considering only the numbers, but when one thinks that 3.4% growth means that on average every 100 Christians brought 3 or 4 new converts into the fold every year, then it doesn’t seem remarkable at all, other than that it seems to have been so consistent. For over three centuries, the fervor of Christians stayed high.

Back to my point, chapter 12. He opens the chapter explaining how little information is still available about Christianity east of Jerusalem. He suggests Syria was the “center of gravity” of the entirety of Christendom until about 700 AD. There apparently is evidence that most of the eastern world had significant Christian populations, including India and China, until the coercive religions arose and wiped them out with the sword. (Of course, I’m referring to Islam, but I’ve only read a couple of pages of the chapter so far. I assume he will note other persecutions and massacres attributable to other religion and culture.)

What I find most remarkable is he concludes that Christians in the west (the Roman Empire) accounted for ONLY a third of all Christians in the year 500. Think of that.

There were tens of millions of Christians in the west. If there were twice as many Christians in the east and in northern Africa, that means the aggressive religions and cultures slaughtered around one hundred million Christians (100,000,000 people of several ethnicities). Actually, even more, since it was over centuries that they were wiped out. There would have been some births and conversions in that time.

Contemplate that.

I always encourage keeping perspective. Try to look at the big picture as well as the details.

The world wars of the 20th Century were horrific, and still in the minds of many of us. Estimates vary, but war deaths through the entire 20th Century are only about as many total as the deaths of Christians who lived in the east before they were extirpated.

Dr. Stark indicates that in many Muslim areas, Christians remained a majority, though repressed, until the beginning of the Fourteenth Century, at which point the Muslims conducted a relentless, violent extermination of the Christians, forcing conversion or death.

I suppose many acquiesced and switched allegiance, but we have ample evidence that a significant proportion of Christians will accept execution rather than renounce Christ.

From chapter 12:

After centuries of gradual decline, the number of Christians in the East and North Africa suddenly reduced to less than 2 percent of the population by 1400. With the fall of Constantinople in 1453, Christianity had been essentially restricted to Europe.

I’ve made assumptions here, and calculated in ways Stark hasn’t suggested (at least not as far as I’ve read to date), but the fact is obvious. Christians of all ethnicities have experienced horrific violence at the hands of other beliefs and cultures.

When it comes to blame and grievance, I believe there never has been and never will be any shortage. On the whole, we are all in this together, and we just better keep working on doing our part to make it better. We must refuse coercion. We must live and act right in our own lives, respecting the life and property of others.

Do good and pray for those who despitefully use you.
