Top Ten Ways the Reformation Changed the World

The first and most important of the principles that drove the Protestant Reformation is the doctrine of Sola Scriptura – Only Scripture:

The belief that the Bible is our only infallible rule and guide in matters of faith and practice. As followers of Christ we acknowledge the authority of the Bible over all else, including the Church and its traditions. This, Sola Scriptura, was the “time bomb” that set off the other ripples that follow. Here are in my opinion the Top 10 ways the Protestant Reformation has

changed the world – and continues to impact us today.

Note: These are not listed in order of importance, but rather in loosely chronological

order of how they developed following Martin Luther’s posting of the famous 95 Theses

on the door of the Wittenberg cathedral on October 31, 1517 – 508 years ago.

*****

1. Sola Fide – Only faith: Justification by faith alone (Romans 1:16-17): The truth that rocked Luther’s world, and then the rest of the western world, is that we

are not justified (made right in God’s eyes) by our works – particularly the buying

of worthless pieces of paper called indulgences. Rather, we are justified *by the

grace of God* through faith in Christ alone. Luther’s revolution – which is really

just a reclamation of a core biblical doctrine, found throughout the Scriptures (see

especially Ephesians 2:8-10) – shattered the established Church’s stranglehold

on the people (first in Germany, then all over Europe) and set ablaze the

revolution that became known as the Protestant Reformation.

2. The imago dei (image of God) in every person (Genesis 1:26-28): Not only the king, the prince, the nobility; not just the Pope, cardinals, bishops – every

person is created in the image of God and worthy of being treated with respect

and dignity. When Luther stood up to the council at Worms, Germany, it was the

first time a common man challenged the powers of Church and State … and lived

to tell about it. In doing so he planted a time bomb that would blow apart the Old

World, the Old Order and open the doorway to the future. This doctrine would

eventually lead to the end of human slavery throughout the Western world as

well as advances in human and civil rights everywhere the Gospel goes.

3. The priesthood of all believers (1 Peter 2:9-10): According to the Bible, the priesthood is not exclusive to just the official, Church-ordained priests. (In the Old Testament, yes; in the New Testament, no.) We no longer need to go to a “priest” to confess our sins, receive absolution – nor engage in unthinking repetitions of

“Hail Mary’s” and “Our Father’s.” This also did away with the idea that only the

priest could receive the elements during the Lord’s Supper and opened it so that

everyone who professes Christ as Lord could participate (see 1 Cor. 11:23-34).

4. The doctrine of vocation (Genesis 1:26-28; Colossians 3:23-24): All work that is legal, ethical and moral is good and legitimate in God’s eyes – not just the

“holy” work of the priest and the bishop. This gave tremendous dignity to the

common man doing common jobs – farmers, miners, tradesmen, craftsmen, etc.

This in turn led to the:

5. Protestant work ethic and capitalism (Colossians 3:23-24): Whatever your opinion of capitalism, it has led to the highest living standards and the greatest

technological advances in human history. How else can you explain a relatively

small, comparatively young nation, the United States of America, going from

being a loosely aligned group of colonies … to the most prosperous nation and

greatest military power the world has ever seen … to being able to put a man on

the moon … in less than 200 years? At the founding of this nation it was

overwhelmingly (98 percent) Protestant, and predominantly Calvinist in belief.

These things, combined with a belief in a shared moral responsibility that work

should be done in honest and ethical ways, have led to unprecedented material

wealth, unparalleled generosity and the emergence of the middle class. It is

worth noting that the Reformers, especially Calvin, always looked at material

prosperity as a means of being able to be generous toward the work of the

Church and the care of the less fortunate.

6. Education (Psalm 119; Colossians 1:28-29): Because the Reformation was so heavily Bible-centric, reading it became essential to the spread of the Gospel and Reformed doctrines. This led to a tremendous increase in literacy all over Europe and beyond. Thanks to Herr Gutenberg’s remarkable invention, the movable-type

printing press, pamphlets, treatises and books became widely available. In

Geneva, Switzerland John Calvin instituted the first widespread “public” school

system whereby all children, not just the wealthy and the nobility, could receive

an education. This also spurred an increase in literacy, which led to the

widespread reading of the Bible, which in turn helped fuel the unstoppable

spread of the Reformation. (It might be of interest that New England, founded

and heavily influenced as it was by the ferociously Reformed Puritans, had a

literacy rate in the mid-19th Century of 95 percent … much higher than it is today.)

7. Bible translation / language itself (John 1:1): Before the Reformation the people did not have access to the Bible in their own languages. The only translation available was in Latin, and nobody read Latin back then, either. Martin

Luther’s German translation of the Bible revolutionized the German language.

Shakespeare, in his plays written during the 1590’s, quoted from Calvin’s

Geneva Bible. The King James Bible had much the same impact on the English

language as Luther’s translation on German; we still use scores of phrases

(“prodigal son,” good Samaritan,” “my brother’s keeper,” etc.) from the King

James Version today. Translation of the Bible into hundreds and hundreds of

indigenous languages has led to more cultures having a written alphabet, and

hence becoming literate, than any other factor.

8. Rise of modern science (Genesis 1; Psalm 19:1-2): The modern notion of “science” grows from, and only from, a biblical worldview – and it began only in post-Reformation northern and western Europe. Oxford professor John Hedley

Brooke says Christianity has influenced the development of modern science in

the following ways:

“1. Christian teachings have served as presuppositions for the scientific enterprise;

  1. Christian teachings have sanctioned science;

  2. Christian teachings supplied motives for pursuing science; and

  3. Christianity played a role in regulating scientific methodology.”

Popular opinion and prevailing secular educational attitudes notwithstanding, science grew not in a climate of “warfare between science and religion,” but rather primarily as a “debate among Christians over the best way to conceptualize God’s role in the world – a debate

over how to construe divine action in a world increasingly understood to operate

by natural law.” Most of the early scientists, including Johannes Kepler, Rene

Descartes, Blaise Pascal, Isaac Newton, Louis Pasteur, Michael Faraday and

many others were either professing Christians or at least operating under a

biblical worldview.

9. Limited government (Romans 13:1-7): The Reformers understood that our rights come from God, not the government, and that the civil government was instituted by God not to provide for all our needs nor to regulate all our activities, but to perform a few basic functions: 1. To restrain evil; 2. To promote the

common good; 3. To execute judgment on those who do evil. They taught that

those who are in authority derive their just powers from the people and that they

are accountable to God for how they conduct themselves while in office. Calvin

said that as such, civil governments are under a covenantal obligation before

God to behave in a moral manner, just as individuals are. If the civil authority is

or becomes immoral and ungodly, they can and should be removed. These

beliefs and principles were obviously extremely influential for the settlers and

Founding Fathers of this nation. The United States is only the second nation ever

founded upon a covenant – Old Testament Israel being the other.

10. Separation of Church and State (Exodus 18:17-27): At the time of the Reformation, the established Church largely dominated the State, to the

detriment of both. It was an unholy alliance, leading to rampant, unrestrained

corruption in both … and the people suffered as a result. The Reformers taught

the two must be separate, and that the Church’s job was not to dictate matters to

the State, nor to serve as its lackey, but to be its conscience and hold the State

accountable for its actions. Martin Luther King, Jr.’s *Letter From A Birmingham

Jail* is a magnificent recent restatement and reaffirmation of these principles. This

is not to imply by any means that the two entities are not to interact with or

overlap with one another, as many today would have us believe, but to say that

neither should dominate or control the other. They each have their God-given,

God-ordained spheres of influence and responsibilities. The Founding Fathers,

while not all Bible-believing Christians, clearly understood this. That’s why

freedom of religious expression is the first right enshrined in the Bill of Rights.

*****

The Protestant Reformation in essence created the modern world. I am aware that the Reformers, including Luther and Calvin, were deeply flawed men (especially from our 21st Century, “enlightened” Western point of view), and that the modern world is not without its flaws and sins. Still, in comparison with every other culture, society, tradition etc. it stands head and shoulders above in terms of the opportunities, freedoms, and

blessings it offers. If you doubt that, ask yourself – why, even today, are so many willing

to risk their lives and even the lives of their entire families to get to the United States?

And it all began with one man reading the Bible.

Frequently asked questions

What was the most important doctrine of the Protestant Reformation?
The most important driving principle of the Protestant Reformation was Sola Scriptura — 'Only Scripture.' It's the belief that the Bible is our only infallible rule and guide in matters of faith and practice. As followers of Christ, we acknowledge the authority of the Bible over all else, including the Church and its traditions. Sola Scriptura was the 'time bomb' that set off every other ripple of the Reformation. From it flowed Sola Fide (justification by faith alone, Romans 1:16-17), the recovery of the priesthood of all believers (1 Peter 2:9-10), the doctrine of vocation (Colossians 3:23-24), the conviction that every person bears the image of God (Genesis 1:26-28), and a long list of cultural consequences — public education, Bible translation, the rise of modern science, limited government, and the separation of church and state. All of it began with one man — Martin Luther — reading the Bible and taking it seriously.
How did the Protestant Reformation lead to public education?
Because the Reformation was so heavily Bible-centric, reading became essential to the spread of the gospel and Reformed doctrine. If you wanted ordinary Christians to read Scripture for themselves, you had to teach them to read. Thanks to Gutenberg's movable-type printing press, pamphlets, treatises, and books became widely available across Europe. In Geneva, John Calvin instituted the first widespread 'public' school system, where all children — not just the wealthy and the nobility — could receive an education. That spurred a surge in literacy, which fueled the reading of the Bible, which in turn fueled the unstoppable spread of the Reformation. It's worth noting that New England, founded and heavily influenced by the ferociously Reformed Puritans, had a literacy rate of about 95 percent in the mid-19th century — much higher than it is today. Education as a public good is a Reformation inheritance.
What is the priesthood of all believers?
The priesthood of all believers is the New Testament teaching that you don't need a Church-ordained priest to mediate between you and God. In the Old Testament, yes — there was a formal priesthood. In the New Testament, no. 1 Peter 2:9-10 calls believers themselves 'a chosen race, a royal priesthood, a holy nation.' This was one of the recovered truths of the Reformation, and it had massive practical consequences. We no longer need to go to a 'priest' to confess our sins or receive absolution. We don't need unthinking repetitions of 'Hail Marys' and 'Our Fathers.' And it opened the Lord's Supper so that everyone who professes Christ as Lord could receive both the bread and the cup, not just the clergy. Every Christian has direct access to God through Jesus Christ — the only mediator between God and humanity.
What is the doctrine of vocation?
The doctrine of vocation says that all work that is legal, ethical, and moral is good and legitimate in God's eyes — not just the 'holy' work of the priest or bishop. Genesis 1:26-28 grounds work in creation itself, and Colossians 3:23-24 commands believers to work 'as for the Lord, not for men.' The Reformation recovered this — and the result was a sweeping dignity given to ordinary jobs done by ordinary people: farmers, miners, tradesmen, craftsmen. Your work matters to God. From that conviction came what's often called the Protestant work ethic — the belief that work should be done with honesty, excellence, and ethical care because it's done before God's face. That conviction, combined with widespread literacy and limited government, helped fuel unprecedented prosperity, the rise of the middle class, and the kind of generosity Calvin always insisted prosperity was for: serving the Church and caring for the less fortunate.
How did the Reformation influence the American Founders?
Heavily. The Reformers taught that our rights come from God, not from government — and that civil government was instituted by God to perform a few basic functions: restrain evil, promote the common good, and execute judgment on those who do evil (Romans 13:1-7). They taught that those in authority derive their just powers from the people, that rulers are accountable to God for how they govern, and that immoral or ungodly civil authority can and should be removed. These beliefs shaped the settlers and Founding Fathers profoundly. The United States is only the second nation ever founded upon a covenant — Old Testament Israel being the other. At the founding, the country was overwhelmingly (about 98 percent) Protestant and predominantly Calvinist in conviction. The Reformers also taught that Church and State must be distinct — neither dominating nor controlling the other (Exodus 18:17-27) — which is why freedom of religious expression is the first right enshrined in the Bill of Rights.
