What Is a Protestant? Romans 1:16-17 Explained
Short answer: A Protestant is a Christian who belongs to one of the church traditions that trace their origin to the sixteenth-century Reformation, and who holds that a person is put right with God by grace alone, received through faith alone, on the basis of Christ's work alone, with Scripture as the final authority. The word itself comes from a protest, but the substance comes from the gospel. Romans 1:16-17 states, "For I am not ashamed of the Good News of Christ, because it is the power of God for salvation for everyone who believes, for the Jew first, and also for the Greek." Paul then grounds that gospel in a righteousness that comes from God by faith. Protestant identity is finally about where a person's confidence rests, not about a denominational logo.
Where the word Protestant actually came from
The term did not begin as a description of a whole branch of Christianity. It began as a legal and political label attached to a group of German princes and city representatives who, in 1529, issued a formal protest at the imperial diet of Speyer. They objected to the revocation of earlier concessions that had allowed reform-minded territories to regulate religious matters in their own lands. The word was originally a nickname for people who protested a specific imperial decision, not a name any of them chose.
Over the following decades the label stuck, and it widened to cover the churches that had broken with Rome or been reformed apart from it: Lutheran territories in Germany and Scandinavia, Reformed churches in Switzerland, the Netherlands, and Scotland, and eventually the Church of England and the many movements that followed. It later crossed the Atlantic and multiplied into hundreds of denominations. So the word is a historical family name, useful but loose.
This matters because the word describes a family, not a single church. There is no global Protestant headquarters, no single Protestant catechism, no one Protestant authority who can speak for all of it. Lutherans, Presbyterians, Anglicans, Baptists, Methodists, Pentecostals, and nondenominational evangelicals differ from one another on baptism, the Lord's Supper, church government, and the work of the Spirit. A Protestant, then, is not defined by agreeing with every other Protestant.
When someone asks what a Protestant is, the honest first answer is historical: a Christian in the church family that emerged from the sixteenth-century reform movements in the West, distinguished from the Roman Catholic and Eastern Orthodox traditions. That answer is accurate but thin. The deeper answer is theological, and it comes from the apostles rather than the reformers. To see it, we have to follow Paul's argument about how a guilty person can stand before a holy God.
The gospel Paul refused to be ashamed of
Paul opens the letter to Rome with a claim that shaped everything the reformers later argued. Romans 1:16 says, "For I am not ashamed of the Good News of Christ, because it is the power of God for salvation for everyone who believes, for the Jew first, and also for the Greek." The gospel is not advice, not a program, and not a community standard. Paul calls it power, the very means by which God rescues people, and he names the channel as believing, not achieving.
Notice who is included. The salvation runs to the Jew first and also to the Greek. Paul will spend much of the letter working out what that means for Israel and for the nations, but the headline is already clear: the same gospel, the same condition of faith, the same Savior for both. No ethnic privilege and no cultural pedigree secures a place at the table. This is why Protestant theology has always insisted that the ground of acceptance cannot be anything a person brings by birth, background, or ritual.
Paul also says he is not ashamed. That is a striking thing to write to a church in the capital of the empire, where the cross was a symbol of humiliation and where a message about a crucified Jew would have looked like weakness. Paul refuses the embarrassment. The apparent foolishness of the message is exactly where its power lies. A Protestant, at least in the historic sense, is someone who refuses to be embarrassed by that message or to dress it up into something more respectable.
So the first plank of Protestant identity is confidence in the gospel itself as God's saving power. Not confidence in a movement, a teacher, a tradition, or a personal experience, but in the message about Christ crucified and risen, delivered to be believed. That confidence is what sent the reformers back to Scripture. If the gospel is God's power, then nothing may be added to it without damaging it, and nothing may be taken from it without hollowing it out.
Righteousness revealed apart from the law
In Romans 3:21-26 Paul explains what the gospel actually accomplishes. He writes that now, apart from the law, a righteousness of God has been revealed, testified to by the law and the prophets. That sentence contains the heart of the Protestant claim. The righteousness that saves a sinner is not produced by the sinner. It comes from God, is revealed by God, and arrives apart from law-keeping, even though the whole Old Testament pointed toward it.
The law and the prophets bear witness, which means this is no innovation. God was always going to justify people this way. The law could describe righteousness and condemn unrighteousness, but it could never manufacture righteousness in a heart that was already bent away from God. Paul's argument leaves no room for a mixed system in which grace starts the process and human merit finishes it. The righteousness is revealed, received, and credited; it is not earned and then rewarded.
This is where the reformers located their central complaint. If righteousness comes from God apart from the law, then it cannot be dispensed as a reward for religious performance, and it cannot be stored, sold, or distributed by an institution. Any practice that turns grace into a commodity to be administered or a treasury to be tapped has already contradicted Paul. The issue was never that sixteenth-century reformers disliked ritual. It was that they could not find a place in Paul's argument for human contribution to the ground of acceptance.
Paul goes on to describe how God can be both just and the one who justifies the ungodly, which is the deepest problem the letter addresses. The answer is the death of Christ, put forward as a propitiation, so that God's justice is honored and the sinner is freely forgiven. Everything a Protestant holds about the cross flows from that. The cross is not a demonstration of divine sympathy; it is the satisfying of divine justice so that forgiveness can be granted without injustice.
Justified by faith, at peace with God
Romans 5:1-2 states, "Being therefore justified by faith, we have peace with God through our Lord Jesus Christ." The order in that sentence is everything. Justification comes first, and peace follows. The believer does not work toward peace, hoping that justification might eventually arrive if the effort holds out. The verdict produces the peace. This is why Protestant teaching about assurance has always been anchored in an objective declaration rather than in fluctuating feelings of closeness to God.
Justification, in Paul's usage, is a legal and relational word. It is the declaration by which God acquits the guilty and counts them righteous on account of Christ, not the process by which they become morally better. Sanctification is real and necessary, but it is a different thing and it comes after. Confusing the two is the engine of endless anxiety, because anyone who looks inside for the basis of acceptance will find a mixed record and no stable ground for peace.
The peace Paul describes is not merely a feeling. It is a settled state of reconciliation. The hostility is ended. The verdict is in. The believer stands in grace rather than under condemnation, and access to God is now open rather than barred. Paul says believers stand in this grace, which means it is a position they occupy, not a mood they sustain. That distinction has carried countless ordinary Christians through seasons when their feelings told them the opposite of the truth.
Faith, then, is not the believer's contribution to salvation, as though it were a good work that tips the scales. It is the empty hand that receives what God gives. This is a crucial point where Protestants have often been misunderstood and sometimes have misunderstood themselves. Trusting is not merit. The person who trusts a doctor is not thereby healing themselves. Faith is only as good as its object, and the object here is Christ, not the quality or intensity of one's own believing.
By grace, not by works, so no boasting
Ephesians 2:8-9 says, "for by grace you have been saved through faith, and that not of yourselves; it is the gift of God." The gift is the whole arrangement: the grace, the salvation, and the faith that receives it. Paul's grammar leaves no ground for self-congratulation. If it were partly earned, there would be something to boast about, and Paul explicitly closes that door. Salvation is a gift, which means the only appropriate response is gratitude, not pride.
Yet grace is not permission to live carelessly. Paul continues that believers are God's workmanship, created in Christ Jesus for good works, which God prepared beforehand. Works have a real and honored place in the Christian life, but they are the fruit of salvation rather than its root. This is the balance that has often been broken in both directions. Some have turned grace into indifference toward obedience; others have turned obedience into a ladder back to acceptance. Paul holds both in order: saved by grace, saved for good works.
Galatians 2:16 states it just as sharply: a person is not justified by the works of the law but through faith in Jesus Christ, and no flesh will be justified by works of the law. Paul wrote that while facing pressure from teachers who wanted Gentile believers to add circumcision and law observance to their faith. His answer was not that the law was evil, but that it was never designed to justify. It diagnoses; it does not cure. Adding law to grace as a basis for acceptance does not strengthen the gospel, it replaces it.
This is why the Protestant instinct about religious performance is so strong. Candles, pilgrimages, disciplines, and ceremonies are not the enemy. The enemy is any teaching that quietly makes them the ground of acceptance, so that a person's standing before God rises and falls with the quality of their performance. That arrangement, however religious, is exactly what Paul rejects, and it is the point on which the Reformation turned.
Scripture, the council, and the argument at Jerusalem
Acts 15 records a dispute that looks remarkably parallel to the sixteenth century. Some men came from Judea and taught the brothers that unless they were circumcised according to the custom of Moses, they could not be saved. A genuine theological crisis followed: what must be added to faith in Christ for a person to be saved? The church gathered, argued, and examined the matter in light of Scripture and the work of the Spirit, and the answer came down firmly on one side.
Peter's contribution is decisive. He asked why the assembly would put a yoke on the disciples that neither they nor their fathers were able to bear. He then declared that they are saved through the grace of the Lord Jesus, in the same way as the Gentiles. That is the same principle Paul argued to Rome and Galatia: grace, received by faith, without the addition of ceremonial requirements as a means of salvation. The council did not invent a new gospel; it refused to add to the one already given.
This is important for understanding what a Protestant actually claims. The Reformation is not treated by its heirs as a new revelation, but as a recovery of an argument the apostles themselves had already settled. The claim is not that the reformers were original, but that they were right in returning to the apostolic answer. Historic Protestants say this plainly, and Roman Catholic and Orthodox Christians disagree, believing the sixteenth-century changes were departures from the church's historic teaching. Honesty requires naming that disagreement rather than pretending it away.
The council also shows how the matter should be handled. They reasoned, they heard testimony, they searched the Scriptures, and they wrote a letter explaining their judgment so the churches could know the basis for it. The pattern is instructive: controversy is not settled by power alone, nor by novelty, but by patient reasoning from what God has already spoken. That conviction, that Scripture is the final authority by which every teaching and practice must be tested, is one of the great distinctives of the Protestant family.
Five emphases, and the label's limits
Historians often summarize Reformation convictions with five phrases: Scripture alone, grace alone, faith alone, Christ alone, and to God alone be the glory. Each is shorthand for a theme the reformers thought the medieval church had obscured. Scripture alone concerns final authority. Grace alone concerns God's unmerited favor. Faith alone concerns the means of receiving it. Christ alone concerns the ground of it. To God alone be the glory concerns the end, that no human or institution should receive the honor that belongs to God.
These slogans are helpful but easy to misuse. Faith alone does not mean faithfulness is optional. Grace alone does not mean God's commands are irrelevant. Scripture alone does not mean the church's creeds, councils, and teachers are worthless; it means they are subordinate and correctable. Christ alone does not mean the Old Testament or the letters of the apostles are dispensable; it means every part of Scripture is read in light of its center, who is Christ himself.
The word Protestant also carries baggage that many bearers today would not claim. It began as a political protest, and it has sometimes been used as a synonym for denominational rivalry or for a vague cultural identity rather than a living faith. There are people who call themselves Protestant mainly because of family history, and people who hold the deepest convictions of the Reformation without ever using the word. The label is a tool, not a test of salvation. Nobody is saved by belonging to the right family category.
Most importantly, the New Testament never uses the word. Paul did not plant Protestant churches, or Catholic ones, or Orthodox ones. He planted churches that confessed Jesus as Lord and gathered around apostolic teaching. So the term is useful for describing a family of traditions and for identifying the convictions that family holds, but it cannot be elevated into a dividing line that Scripture itself does not draw. Where believers differ on church order, sacraments, and history, they should do so with honesty and generosity, while holding fast to the gospel both sides say they treasure.
What this means for an ordinary believer
If the heart of Protestant identity is what Paul describes, then the practical question is simple: where is your confidence resting? Is it in your record, your religious activity, your family background, or your sincerity? Or is it in Christ, who died and rose, and whose righteousness is received by faith and not earned? A person can be a card-carrying Protestant in name and still live like a careful legalist inside, endlessly trying to quiet the conscience with performance.
The letter to Rome was written to a church Paul had never visited, made up of Jewish and Gentile believers who had to learn to receive one another. The gospel he preached did not merely rescue individuals; it created a new people who had no basis for ranking one another. If justification is by faith, then the longtime religious insider and the brand-new outsider stand on the same footing, and neither can look down on the other. That has obvious implications for how churches treat newcomers, outsiders, and people whose backgrounds differ from the majority.
The Reformers recovered, they believed, was not a new teaching but an apostolic one, and they staked their lives on it. A Protestant today inherits that recovery. But inheritance is not the same as faith. The question is whether the same gospel that gave the sixteenth-century reformers peace is the gospel a person is actually trusting. That is not a question about church history; it is a question about where a soul rests when it stands before God.
So a Protestant is, historically, a Christian in the church family descended from the Reformation. Theologically, a Protestant is a Christian who answers the question of acceptance with grace alone, received through faith alone, on the basis of Christ alone, with Scripture as the final authority. That answer is not the invention of a movement. It is the answer Paul gave to Rome, and it remains good news for anyone who will believe it.
Biblical fidelity check
These passages do establish something specific. They establish that salvation is God's power, that it comes to everyone who believes, that righteousness is revealed from God apart from law-keeping, that justification is by faith and produces peace with God, that it is a gift rather than a wage, and that no flesh will be justified by the works of the law. They also establish that the early church, after real debate, refused to make circumcision or ceremonial law-keeping a condition of salvation for Gentiles. These are clear and repeated apostolic claims, not isolated verses.
These passages do not establish everything that has been attached to the label over the centuries. They do not prescribe a particular church government, a specific sacramental theology, a list of denominations, or a political program. They do not say the church's teaching is worthless, nor that every ancient practice must be discarded. They also do not settle every question about how God's grace and human responsibility relate in detail, a matter on which faithful teachers have differed. A common misreading is to turn faith alone into a license for careless living, as though good works were irrelevant. Paul rejects that directly, insisting believers are created in Christ for good works. Another misreading is to treat the label Protestant as itself a mark of salvation, which Scripture nowhere suggests.
Other passages that speak to Romans 1:16-17
If you want to follow this theme further, several studies pair well with Paul's statement that the gospel is God's power for salvation. One looks at the practical outworking of life in the Spirit, asking What does Galatians 5 mean by fruit of the Spirit? — a necessary companion to any talk of grace, since it shows what God's work produces in a life. Another examines the renewed mind that follows from mercy already received, What does Romans 12:2 mean by renewing your mind? A third considers how the gospel holds up when circumstances do not, What does Romans 8:28 mean when life hurts? And a fourth turns to spiritual conflict and the resources God provides, What does Ephesians 6 teach about the armor of God?
Frequently asked questions
Is a Protestant the same thing as an evangelical?
Not exactly. Protestant describes the broader church family that emerged from the sixteenth-century Reformation, including Lutheran, Reformed, Anglican, Baptist, and Methodist traditions. Evangelical is narrower and focuses on convictions such as the authority of Scripture, the centrality of the cross, the necessity of conversion, and active sharing of the gospel. Many Protestants are evangelicals and many evangelicals are Protestants, but the two circles do not overlap completely. Some Protestant bodies are theologically liberal and would not call themselves evangelical, and a few evangelicals belong to churches that do not use the Protestant label.
Does being Protestant mean I can ignore good works?
No. Paul's own letters refuse that conclusion. Good works are the fruit of salvation, not its root, and Ephesians says believers are created in Christ Jesus for good works, which God prepared beforehand. The distinction is about order and ground, not about importance. A person is accepted because of Christ, and that acceptance produces a life of obedience out of gratitude rather than fear. Where someone uses grace as an excuse for sin, they have misunderstood the very grace they claim, since the grace that justifies also teaches and transforms those who receive it.
Do I have to be a Protestant to be saved?
No. Salvation is not a matter of membership in the right tradition; it rests on Christ and is received by faith. Faithful Christians in Catholic, Orthodox, and Protestant churches all confess Jesus as Lord and Savior. The disagreements between these families are real and worth studying carefully, especially about authority, sacraments, and how justification relates to transformation. But Paul's argument in Romans is aimed at where a person's confidence rests, not at which visible congregation they attend. Belonging to a Protestant church is no substitute for personally trusting Christ.
