The Reformation
The Reformation
From Luther to Arminius and Beyond
The Protestant Reformation did more than divide Western Christianity. It forced Christians to ask foundational questions about Scripture, grace, faith, salvation, church authority, human freedom, and the sovereignty of God. Those questions did not end with Martin Luther—and they still shape Protestant theology today.
The Reformation was not one argument, one man, or one moment.
It was a movement.
And like most great movements, it began with a question that eventually produced many more questions.
How is a sinner made right with God?
Who has final authority in the church?
What role do faith and works play in salvation?
How free is the human will?
Does God choose those who will be saved?
Can saving grace be resisted?
Can a true believer finally fall away?
What started with calls for reform eventually produced Lutheran, Reformed, Anglican, Anabaptist, Arminian, Methodist, Baptist, evangelical, and other Protestant traditions.
To understand Protestant Christianity today, it helps to understand the theological road from Luther to Calvin, from Calvin to Arminius, and beyond.
Christianity in Late Medieval Europe
By the beginning of the sixteenth century, the Western church had accumulated enormous religious, cultural, and political influence.
It also faced serious problems.
Church offices could become entangled with wealth, family influence, and political power.
The preaching and financing of indulgences could obscure the biblical meaning of repentance and forgiveness.
Ordinary Christians often depended heavily on clergy rather than reading Scripture directly in their own language.
Many believers struggled with questions of merit, penance, grace, assurance, and their standing before God.
Reform did not come out of nowhere.
There had been earlier reformers and critics.
But the invention of movable-type printing, political changes, Renaissance scholarship, and growing access to biblical texts created conditions in which reform could spread rapidly.
The Question That Ignited the Reformation
Martin Luther began as an Augustinian monk and professor struggling intensely with the holiness of God and the guilt of sin.
His central question was deeply personal:
How can an unrighteous sinner stand before a righteous God?
Luther came to understand justification as God’s gracious declaration that the believer is righteous through faith in Christ.
“The righteous will live by faith.”
Romans 1:17, NIV
This conviction placed him in conflict with the church’s late medieval systems of merit, penance, and indulgences.
In 1517, his famous Ninety-Five Theses challenged abuses surrounding indulgences.
The debate soon moved far beyond indulgences.
The Five Solas
Later Protestant theology often summarized Reformation convictions through five Latin phrases.
Scripture Alone
Scripture is the final authoritative standard for Christian doctrine and practice.
Grace Alone
Salvation begins and ends with God’s grace, not human merit.
Faith Alone
We are justified through faith rather than through works that earn God’s favor.
Christ Alone
Christ is the sufficient mediator between God and humanity.
To God Alone Be Glory
Salvation ultimately magnifies God’s grace, wisdom, power, and glory.
Scripture reveals a salvation accomplished by Christ, given by grace, received through faith, and resulting in glory to God.
Justification by Faith
For Luther, justification was not a minor theological adjustment.
It changed the way salvation itself was understood.
“Therefore, since we have been justified through faith, we have peace with God through our Lord Jesus Christ.”
Romans 5:1, NIV
The sinner does not gradually become worthy enough to earn acceptance.
Rather, God justifies the ungodly through faith in Christ.
Good works remain important.
But they become the fruit of salvation rather than its foundation.
We are not accepted because our works are good enough. We are accepted because Christ is.
Ulrich Zwingli: Reform Spreads Beyond Germany
Luther was not the only reformer.
In Zürich, Ulrich Zwingli developed a reform movement with many similarities to Luther’s but also important differences.
Zwingli strongly emphasized biblical authority and sought to remove church practices he believed lacked biblical warrant.
He and Luther agreed on many major issues.
But they famously disagreed over the Lord’s Supper.
Luther strongly defended Christ’s real presence in Communion.
Zwingli placed greater emphasis on the Supper as a memorial and confession.
One lesson became clear very early: agreement about reform did not guarantee agreement about every doctrine.
Reformation Theology Becomes a Broader System
John Calvin belonged to the second generation of Protestant reformers.
Born in 1509, he was younger than Luther and inherited a movement already underway.
Calvin agreed strongly with the Reformation emphasis on Scripture, grace, faith, and Christ.
But his theology developed into a more comprehensive account of God’s sovereignty, salvation, church life, worship, and Christian discipleship.
His most influential work, Institutes of the Christian Religion, became one of the foundational texts of the Reformed tradition.
Calvin Put God’s Glory and Sovereignty at the Center
Calvin’s theology begins with the greatness of God.
God is Creator.
God is sovereign.
God rules history.
God initiates salvation.
God preserves His people.
“For from him and through him and for him are all things. To him be the glory forever!”
Romans 11:36, NIV
This emphasis raised an important question.
If salvation is entirely by grace, how should we understand God’s choice of those who are saved?
Did God Choose Us Before We Chose Him?
Reformed theology answered strongly: yes.
“For he chose us in him before the creation of the world.”
Ephesians 1:4, NIV
In classic Reformed theology, God’s election is not based on foreseen human merit.
Nor is it ultimately grounded in the idea that God looked into the future and selected those He saw would choose Him.
Election rests in God’s gracious purpose.
Grace is grace precisely because salvation begins with God rather than with us.
The Anabaptists Went Further
Not every reformer believed Luther, Zwingli, and Calvin had reformed the church far enough.
Groups broadly called Anabaptists argued for a more radical return to New Testament patterns.
Many emphasized:
Baptism should follow personal faith rather than be administered automatically to infants.
Church membership should consist of professing disciples.
Civil government should not compel Christian faith.
Following Jesus should visibly transform how believers live.
Many Anabaptists suffered persecution from both Catholic and Protestant authorities.
England Took a Different Path
The English Reformation developed differently from events in Germany and Switzerland.
Political concerns involving Henry VIII played a major role in England’s separation from Rome.
But over time, Protestant theology increasingly shaped English church life.
The Church of England developed a distinctive identity that retained much historic liturgy and church structure while embracing significant Reformation doctrines.
From the English Reformation would eventually emerge Puritans, Separatists, Baptists, and other movements with enormous influence on English-speaking Christianity.
Then Came a Debate Within the Reformed Church
Jacobus Arminius was not originally an outsider attacking Protestantism.
He was a Dutch Reformed minister and theologian.
Born in 1560, Arminius inherited Reformation theology rather than creating a rival religious system from scratch.
He affirmed many Protestant convictions.
Scripture.
Human sinfulness.
The necessity of grace.
Salvation through Christ.
Justification through faith.
But he questioned some interpretations of predestination developing within Reformed theology.
How Do Grace and Human Response Fit Together?
Arminius did not argue that sinners could save themselves.
He agreed that divine grace is necessary.
The debate concerned the nature and effectiveness of that grace.
Reformed theologians emphasized God’s effectual call: God’s saving grace successfully brings the elect to faith.
Arminian theology emphasized enabling grace that genuinely makes faith possible while allowing that grace to be resisted.
The argument was not grace versus human effort. It was about how God’s grace works in bringing a sinner to faith.
The Remonstrance of 1610
Arminius died in 1609.
The controversy continued after his death.
In 1610, his followers issued a document known as the Remonstrance.
It summarized several key convictions.
Election was understood in relation to faith in Christ.
Christ died for all people, though only believers receive the saving benefits of His death.
Fallen human beings cannot produce saving faith without divine grace.
God’s gracious work may be resisted.
The early Remonstrants initially expressed caution about whether a true believer could finally fall away.
The Reformed Response
The controversy led to the Synod of Dort, held from 1618 to 1619.
Reformed theologians rejected the Remonstrant position and issued doctrinal statements defending what became known as the doctrines of grace.
Much later, these teachings were commonly summarized by the acronym TULIP.
Sin affects the whole person, leaving sinners unable to come to God apart from grace.
God’s saving choice rests in His grace rather than foreseen human merit.
Often called definite atonement: Christ’s death effectively secures the salvation of His people.
God’s effectual saving call ultimately brings His people willingly to Christ.
Those truly united to Christ will ultimately be preserved in faith.
Reformed and Arminian Theology Side by Side
Arminian Theology Takes a New Form
More than a century after Arminius, John Wesley became one of the most influential advocates of an Arminian approach to salvation.
Wesley strongly emphasized grace.
But he also emphasized the universal Gospel invitation and the real responsibility of human beings to respond to God’s gracious call.
Wesleyan theology became known especially for the idea of prevenient grace.
This refers to God’s grace acting before conversion, enabling fallen people to respond to the Gospel without suggesting that they can save themselves.
Wesley also strongly emphasized sanctification and holy living.
His ministry eventually helped give rise to Methodism and later influenced numerous holiness and evangelical movements.
Protestant Theology Became Even More Diverse
Baptists developed out of the English Separatist and Puritan worlds in the seventeenth century.
But Baptists themselves divided over questions of grace, election, and atonement.
Reformed Baptist Tradition
Particular Baptists embraced much of Reformed soteriology, including definite atonement and doctrines of grace.
Arminian-Leaning Tradition
General Baptists emphasized a general or universal atonement and often held views closer to Arminian theology.
The Reformed-Arminian question therefore crossed denominational boundaries.
The Reformation Still Shapes Evangelical Christianity
Most evangelical Christians today inherit theological assumptions shaped by these debates whether they realize it or not.
When Christians discuss:
they are participating in conversations shaped by centuries of Reformation history.
Luther, Calvin, Arminius, and Wesley Agreed on More Than We Sometimes Admit
Their disagreements were serious.
But they were disagreements within a broader Christian and Protestant framework.
They disagreed over how grace operates, not over whether sinners need grace.
Because Scripture Contains Truths We Find Difficult to Hold Together
The Bible strongly teaches God’s sovereignty.
“He chose us in him before the creation of the world.”
Ephesians 1:4, NIV
Scripture also calls people genuinely to respond.
“Repent and believe the good news!”
Mark 1:15, NIV
Scripture says no one comes unless drawn by God.
“No one can come to me unless the Father who sent me draws them.”
John 6:44, NIV
Yet Scripture also warns people against resisting God.
“You always resist the Holy Spirit!”
Acts 7:51, NIV
Theological systems are attempts to explain how all these truths fit together.
Good Theology Can Still Produce Bad Behavior
The Reformation produced extraordinary biblical renewal.
It also produced conflict.
Political struggle.
Persecution.
Bitter controversies.
Protestants sometimes persecuted other Protestants.
Catholics and Protestants both participated in violence.
Christians who defended grace sometimes behaved ungraciously toward one another.
Right doctrine does not excuse pride, cruelty, dishonesty, or contempt.
“Knowledge puffs up while love builds up.”
1 Corinthians 8:1, NIV
The Reformation Matters Because the Gospel Matters
Christians can become strangely passionate about theological labels.
Calvinist.
Arminian.
Lutheran.
Wesleyan.
Baptist.
Reformed.
Those categories can be useful.
But none of them is the Gospel.
“Believe in the Lord Jesus, and you will be saved.”
Acts 16:31, NIV
We are not saved by understanding predestination correctly.
We are not saved by rejecting Calvinism.
We are not saved by mastering Arminian theology.
We are saved by Jesus Christ.
Theology matters because it helps us understand Christ. It becomes dangerous when the system becomes more precious to us than the Savior.
Seven Lessons From the Reformation
The Reformation Never Really Ended
The historical Reformation belongs to the sixteenth and seventeenth centuries.
But the deeper work of reform continues.
Every generation faces the temptation to replace biblical Christianity with something easier.
Tradition without Scripture.
Morality without grace.
Spirituality without Christ.
Politics without the Gospel.
Emotion without truth.
Doctrine without love.
Church growth without discipleship.
The Reformation reminds us that churches themselves sometimes need to be called back to the center.
The church is always in danger of drifting. The answer is always to return to Christ and His Word.
From Luther to Arminius and Beyond
Luther asked how sinners can be right with God.
Calvin emphasized the sovereignty and glory of God in salvation.
Arminius asked how divine grace relates to genuine human response.
Dort defended the Reformed doctrines of grace.
Wesley carried Arminian theology into a powerful evangelical movement.
Baptists, Methodists, Presbyterians, Lutherans, Anglicans, Reformed churches, and countless evangelical traditions continued the conversation.
And Christians are still discussing the same questions.
How sovereign is God?
How free are we?
How does grace save?
Why do some believe?
Will God keep those who belong to Him?
Those are important questions.
But the Reformation’s greatest truth is simpler than all of them.
“For it is by grace you have been saved, through faith—and this is not from yourselves, it is the gift of God.”
Ephesians 2:8, NIV
Grace is the beginning.
Christ is the center.
And God gets the glory.
