Brief History of Christianity's Worldwide Expansion

TL;DR:
Christianity’s global expansion unfolded in five major 400-year “epochs.” Early missionaries like Patrick, Boniface, and Francis modeled courageous cross-cultural witness, while later figures such as Carey, Taylor, Townsend, and McGavran shaped modern Protestant mission efforts and focused attention on unreached peoples. Factors that have aided the global spread of Christianity include Bible translation, contextualization, trade and travel, influential converts, humanitarian outreach, political and colonial expansion, and even persecution, which often strengthened believers’ witness.

How Did Christianity Become Such a Worldwide Religion?

Question:I hate history classes with all of those dates and names and garbage like that. Will this be another boring lecture stuffed with that kind of material?

I could overwhelm you with thousands of missionary names, hundreds of significant dates, and numerous trends that help explain the worldwide spread of the gospel. Instead, I’ll resist the temptation to swamp you with information.

I hope you'll devour and internalize Ralph Winter's wonderful encapsulation of world missions history in his 5 epochs of redemption history. Make this oversimplified historical summary the one thing you take away from this week's study:

Remember that these 400-year periods are very rough approximations. Winter is not using them to pinpoint things precisely. He came up with them as a memory device. (See my PowerPoint presentation on this theme.)

Question: St. Patrick is mentioned in this week's reading. Is this the same guy whose life people celebrate by drinking green beer?

The March 17 celebration of St. Patrick's Day shouldn't be about leprechauns and green beer and rainbows with pots of gold.

Patrick, who lived during the 400s, was a young man from Roman Britain who was captured by Irish raiders and taken to Ireland. While enslaved on a farm there, he was converted. Eventually, he escaped and went home. But Patrick felt called to return to his former pagan captors as a missionary. He did and led much of Ireland to faith in Christ.

Three-leaf cloverAccording to a longstanding tradition, Patrick used the three-leaf clover to illustrate the Trinity. This story forever tied Patrick and Ireland to the shamrock. Sadly, the shamrock that's sometimes used in decorating for St. Patrick's Day is the four-leaf kind.

Next time March 17 rolls around and you see leprechauns, pots of gold, and 4-leaf clovers, think how disgusted Patrick would be at what we've made of his life.

"Patrick saw God's fingerprint in the three-leafed clover and used the three-leaf clover to try to explain the Trinity to the Irish. Patrick not only saw God's fingerprint, he became God's fingerprint through his life and the people he influenced." — Veronica Roesley, Northwest Nazarene University graduate student

Another of my heroes of that period is Boniface, who dared to march in a German forest one day and defy the pagan gods by chopping down a huge sacred oak tree. In a further act of defiance, this missionary to some of my ancestors used wood from that fallen tree to build a chapel.

Question: St. Francis of Assisi is mentioned in this week's reading. Isn't he the man who preached to the birds and wrote the little prayer about being an instrument of peace?

Yes, he was. Francis and Ramon Llull were two of the few people during that bloody period of the Crusades who tried to witness to Muslims. Francis actually went to Egypt, met with the Sultan, and talked to him about Christ. Llull devoted many years to evangelizing Muslims and reportedly died from injuries sustained after being stoned in North Africa.

"To read of Ramon Llull's willingness to leave nobility to reach the Muslims ("the Fool of Love") should challenge each of us to ask if we are that willing to be of use by God." — Kevin Bottjen, Northwest Nazarene University graduate student

Question: Wouldn't it be great to see the tremendous results that those early pioneer missionaries saw?

William Carey served for seven years before he had his first convert in India. Adoniram Judson worked in Burma for almost the same period of time before he had his first convert.

What about Robert Morrison, the first Protestant missionary to China, who labored for 25 years and had fewer than a dozen converts?

Or what about Ansgar, the Apostle of the North, who gave his life to preaching the gospel to the Vikings without any visible long-lasting results?

What about the missionaries to East Africa who shipped their belongings in coffins because they knew disease or violent opposition might take their lives during their first term?

What about Jim Elliot, Nate Saint, and three other missionaries who were martyred on an Amazon tributary sandbar in Ecuador as they made the first attempts to reach the Waorani indigenous tribal people with the gospel?

I stand in awe of these pioneer missionaries. Many of them died without seeing great results. Yet, many of the outposts they planted eventually flourished as the gospel took root in culture after culture.

Question: Does this have anything to do with Nazarenes?

It does. Our denomination was born at the turn of the last century. The 1800s were a period that historian Kenneth Scott Latourette calls "The Great Century" of Protestant missions. The early Protestant Reformers had shown little interest in global evangelism. Then, in a 100-year period, Protestant missionary activity swelled to incredible proportions.

At the end of the 1700s, Christianity’s greatest concentrations were in Europe and the Americas, although historic Christian communities also remained in Africa, the Middle East, and parts of Asia. By 1900, Christianity had become a truly global religion.

I think the fact that we were born in that atmosphere of enthusiasm for world evangelism contributed much to the missionary spirit of our denomination.

Let's come back to Ralph Winter's explanation of the three world missions eras influenced by four men. There's a poignant phrase attached to three of the personalities involved:

William Carey
"Young man, sit down. When God chooses to save the heathen, he'll do so without your help or mine" (said by Baptist minister).
Hudson Taylor
"There's too much work yet to do here. We've got to properly finish the job here before we can even think of going to other places" (said by other missionaries in China when Taylor wanted to move to cities in the interior of China)
William Cameron Townsend
"How come your God doesn't speak my language?" (said by Guatemalan Indian to whom Townsend was trying to sell a Bible in Spanish)

As for Donald McGavran, he became obsessed by several thoughts. Among them:

  1. God wants His lost children found.
  2. People like to become Christians without having to feel that they need to cross racial, linguistic, or cultural boundaries in order to do so.
  3. Healthy churches can best fulfill the Great Commission. Many of the diseases that weaken churches can be kept at bay or cured.

Here's a question for reflection: Were these people whom I've mentioned, as well as others you encountered in your reading, spiritual giants? Did they reach a level of spirituality that is out of reach for you and me?

Discussion questions

  1. In what ways can Ralph Winter's five epochs of redemption history help us to comprehend the history of the expansion of Christianity? In what ways are these periods different from each other?
  2. What can we learn from the lives of early Christian missionaries like Patrick, Boniface, and Francis of Assisi? How might their stories inspire us to share the gospel today?
  3. Why do you think it took many early Christian missionaries years or even decades to see their first converts? In what ways should their persistence and dedication guide our own efforts to fulfill the Great Commission?
  4. How have the ways in which Christians share the gospel changed throughout history, from the Roman Empire to modern-day missions? Are there lessons to be learned from these changes?
  5. How might understanding the history of Christianity's global expansion help us to better appreciate the diversity and richness of the global Church today? How can we use this knowledge to promote greater unity and cooperation among believers?

Nine Things Furthering Global Outreach

Several factors have contributed to the worldwide spread of Christianity. Here are nine of them:

  1. Christianity's spread has been greatly aided by missionaries who traveled the world to spread the gospel. From the early apostles to modern-day missionaries, Christ-followers have sought to introduce Christianity to new areas of the globe and to previously unreached ethnolinguistic groups.
  2. Christianity has the capacity to be contextualized for different cultural settings. When contextualized well, it no longer feels like a foreign intrusion.
  3. The expansion of trade routes and travel networks, particularly during periods like the Roman Empire, contributed to the spread of Christianity to new regions. Air travel via small planes and helicopters is doing the same thing today.
  4. The translation of the Bible into thousands of languages has made the message of Christianity accessible to people who otherwise would have had little access to it.
  5. The conversion of influential individuals, such as rulers, kings, or intellectuals, has sometimes led to mass conversions within their spheres of influence.
  6. Christian organizations and churches have often provided social services and humanitarian aid that has helped to establish trust and goodwill and even opened the door to share the gospel.
  7. Throughout history, political leaders and rulers have embraced Christianity, sometimes out of personal conviction and other times for political reasons. Sadly, this political support has occasionally led to the adoption of Christianity as a state-sponsored religion, a development that has not always served the gospel well.
  8. European colonial expansion often created routes through which Christianity spread, although missionaries’ relationships with colonial authorities varied widely. Sadly, an outward acceptance of Christianity was sometimes imposed on indigenous populations alongside political and economic dominance.
  9. Paradoxically, persecution and martyrdom tend to strengthen the resolve of believers and attract attention to the Christian faith. That has led to its spread in unexpected ways.

"My previous education regarding church history focused on notable theological developments and controversies, important figures in the intellectual history of the church, and various schisms, but not the geographical and cultural spread of the church." — Scott Powell, Nazarene Bible College student
