Theological claims· 11
  1. The practice of selling indulgences rests on the grotesque, unbiblical doctrine of purgatory, which denies that believers can be fully justified. unit #5
  2. Righteousness required for salvation means perfect law-keeping in word, thought, and deed, both inwardly and outwardly. unit #8
  3. Human beings cannot achieve the perfect righteousness God requires because they are born in sin and incapable of perfect law-keeping in word, thought, and deed. unit #9
  4. Scripture teaches justification by faith alone, not by doing your best in this life and suffering in purgatory to complete what is lacking. unit #10
  5. Justification is by grace alone, meaning it is a gift that cannot be earned — if you earn it, it is wages, not grace, and there is nothing to boast about when receiving a gift. unit #15
  6. Justification is by the grace of God alone with no human contribution, and the Roman Catholic Church preaches another gospel by requiring temporal punishment in purgatory even after justification, condemning those who believe grace alone is sufficient. unit #16
  7. Justification is through Christ alone because only the atoning work of Christ can satisfy the righteous wrath of God against sin. unit #17
  8. Propitiation from God's wrath is necessary, and we must discuss it because Scripture does. unit #20
  9. Understanding God's mercy requires understanding the wrath we deserve, and facing our guilt and incapacity without hope drives us to the only answer: grace alone, faith alone, in Christ alone. unit #22
  10. Justification comes through the double imputation of Christ's active obedience (His perfect righteousness imputed to us) and passive obedience (our sin laid upon Him and nailed to the cross). unit #25
  11. Christ purchased us by His blood, paying the price we owed and could never pay ourselves, accomplishing justification by grace alone, through faith alone, in Christ alone. unit #26

0 · Baucham opens by acknowledging students' musical contribution, directs the congregation to Romans 3:21, and announces the sermon's focus on justification by faith — the central doctrine of the Reformation

Good morning again. Thank you, students, for both of those songs today. We're grateful for your contribution and want to be an encouragement to you as you move on to the next phase in your journey. If you have your Bibles open with you today, open them to Romans chapter 3. Romans chapter 3. We've heard this text read in our hearing already. this morning, Romans chapter 3, beginning at verse 21. I won't read it again, but I'll remind us that the theme for today is the Reformation doctrine of justification by faith.

1 · Provides historical context for the Reformation, explaining that Luther's 95 Theses on October 31, 1517, were intended as debate points, not a revolutionary manifesto, yet they sparked the Reformation despite Luther's intentions and continued Catholic identity at the time

We celebrate the Reformation. usually were reminded of it on October 31st, because on that day, October 31st, 1517, Martin Luther ignited the Reformation really in earnest when he nailed his 95 Theses to the door of the church in Wittenberg, Germany. At that time, Martin Luther was still very much a Roman Catholic. He was very much a monk. He was very much committed to Roman Catholic doctrine. The 95 Theses were points to be debated. He had seen things with which he was fed up, and he wanted to debate, not start the Reformation. But start the Reformation he did.

2 · Establishes the financial motivation behind the practices Luther opposed: the construction of St

In order to understand how that connects to this doctrine of justification by faith, and why that is really the essence of the Reformation, one needs to understand a bit about what led Luther to his response. St. Peter's Cathedral in Rome was being built, that same cathedral that you can go to and visit today, most noted for the painting in the ceiling in the Sistine Chapel. It costs what today would be hundreds of millions of dollars. And in order to raise money, there were a number of different tactics that were used. One of them, there was a German bishop who wanted to buy a second bishopric, which wasn't allowed. However, the church needed money to finish the cathedral, so they charged him an insane amount of money. in order to get that second bishop.

3 · Explains Roman Catholic theology undergirding indulgences: the sacramental and sacerdotal system where grace is dispensed through seven sacraments administered by priests, visualized as a jug that fills with grace through sacraments and empties through sin, requiring purgatorial suffering to complete what was left unfilled at death

And one of the many things that they were doing to raise this money was selling what are called indulgences. Indulgences are things that you can buy from the church in order to buy time off your sentence in purgatory. Let me say that again. Indulgences were things that you could buy from the church in order to knock off time from your sentence in purgatory. You see, Roman Catholicism is a sacramental and sacerdotal religion. Sacramental means that grace is dispensed through the sacraments. There are seven sacraments of the Roman Catholic Church. And by participating in those sacraments, sacerdotal means those sacraments have to be dispensed by the priest. This is where the church gets its power from. In order for you to be right with God, you have to receive those sacraments. In order for you to receive those sacraments, you have to receive them from the priest. Sacraments like baptism, your first communion, penance and confession. Sacraments like the Eucharist, as they would call it, we would call the Lord's Supper. Sacraments like marriage and holy orders and last rite. These sacraments, if you think about it like a jug that you fill up with water. You go and you experience these sacraments and it fills up this jug with grace. Now when you sin, you lower the level in the jug and you have to go for more sacraments so that you can fill up the level in the jug again. You sin, the level goes down. Go get some sacraments, the level goes up. The jug is never completely full. So when you die, you finish filling the jug by suffering in purgatory. Now, you may have to suffer for 1,000 years or 10,000 years based upon how full you were able to get your jug in this life.

4 · Provides a vivid historical example of Johann Tetzel's theatrical sale of plenary indulgences, showing how the doctrine of purgatory was exploited for fundraising through emotional manipulation — appealing to grief and familial love while a monk held his hand over fire to dramatize suffering

Needless to say, you have to pay after you die to finish earning your way to heaven. So why sell indulgences? Well, one of the things that they were doing is selling what are called plenary indulgences. What's a plenary indulgence? A plenary indulgence is an indulgence that you can buy to fill up your jug completely. Well, there's a small problem. If I go today and buy a plenary indulgence and I fill up my jug completely, before I make it back home, I've sinned again and my jug is no longer full, which is why plenary indulgences are purchased for the dead. There's a famous monk by the name of John Tetzel, Johann Tetzel. He was going around selling plenary indulgences to collect money to finish building St. Peter's Cathedral in Rome. He was a man of many theatrics. He would do things like put his hand over a fire in front of a crowd, and the crowd would begin to scream for him to stop. And when he would stop, he would use this famous phrase, whenever a coin in the coffers ring, a soul from purgatory springs. Do you not love your dearly departed grandmother? Do you not love your dearly departed father, sister, brother? Would you not release them from suffering in purgatory if you could, as he holds his hand over a fire? In other words, give some money to help build the cathedral in Rome And instantly, instantly, your loved one will be released from purgatory and go to heaven. Now, who, if they were able to do it, would not stop the suffering of their dearly departed relative?

5 · Asserts that Luther's protest moved from objecting to the practice of selling indulgences to attacking the theological foundation itself — the doctrine of purgatory and its denial of full justification — a system still operative in Roman Catholicism today

Martin Luther watched this, and he was appalled. He wanted to debate this practice. But he ended up starting a reformation that debated the very foundation upon which this practice is built. The only reason you have practices like this, by the way, you can buy indulgences today in Roman Catholicism. The only reason we have practices like this is because of this grotesque, unbiblical doctrine of purgatory. this grotesque, unbiblical doctrine that somehow you can never be fully justified.

Christ is beautiful not because of His physical appearance—which Scripture says was unremarkable—but because the gospel of His substitutionary death on the cross is the only solution to humanity's sin problem and the only means by which guilty sinners can approach a holy God without experiencing His wrath.

A father's heart, modeled in Proverbs and fulfilled in the gospel, seeks not merely to inform his children with basic instruction or transform them through moral formation, but ultimately to lead them to redemption through repentance and faith in Christ.

Memory verse this week

Romans 3:24

and are justified by his grace as a gift, through the redemption that is in Christ Jesus

Why this verse: This verse is the doctrinal heartbeat of the entire sermon, crystallizing the central Reformation claim that justification is grace alone, through Christ alone, received as a gift that cannot be earned. Memorizing this single verse arms the congregation with the essential biblical refutation of any system that conditions salvation on human works, merit, or purgatorial suffering.

Daily readings · Monday–Friday

5-day reading plan

This week we walk through the Reformation doctrine of justification by grace alone, through faith alone, in Christ alone — beginning with Abraham's exemplary faith, moving through God's wrath and our incapacity, and culminating in Christ's atoning work that accomplishes what we cannot.

Monday Genesis 15:6

Abraham believed God, and it was counted to him as righteousness — not because of his deeds, but because of his trust in God's promise. In this single verse, the entire Reformation doctrine finds its Old Testament anchor: justification comes through faith, not through human achievement or the accumulation of works. We, like Abraham, are justified not by what we do but by what we trust God to do.

Tuesday Romans 1:18

God's wrath is revealed from heaven against all ungodliness and unrighteousness — and this is not a side doctrine but the essential context for grasping grace. Until we feel the weight of divine wrath against sin, mercy remains cheap sentiment rather than scandalous gift. The gospel humbles us as we grasp that we are the targets of this wrath, and only in that terror do we run to Christ.

Wednesday 2 Corinthians 5:21

He made Him who knew no sin to be sin on our behalf, that we might become the righteousness of God in Him — the cosmic exchange at the heart of justification. Christ takes our guilt and death; we receive His perfect obedience and standing before the Father. In this single verse, the double imputation stands complete: our sin flows to Him, His righteousness flows to us, and the justice of God is perfectly satisfied.

Thursday Mark 10:45

The Son of Man came to give His life a ransom for many — a price paid, a debt satisfied, a purchase completed. We could never accumulate the merit or endure the punishment our sin demands; Christ alone could and did. Grace means this ransom was given freely on our behalf, not because we earned it but because He chose to pay what we owed.

Friday Romans 9:30-32

Israel pursued righteousness as if by works, but stumbled over the stone — the tragic irony of trying to earn what God offers as a gift. We, like Israel, stand incapable of the perfect law-keeping God requires; yet faith alone unites us to Christ, who fulfilled the law in our place. The five solas stand together: by grace alone, through faith alone, in Christ alone, for God's glory alone, as Scripture alone declares.

Can We Ever Be Good Enough?

For the parent

This prompt anchors in the sermon's central claim: that perfect law-keeping is impossible for human beings, which is why grace through faith is our only hope. Listen for how your children understand their own inability and God's provision — this opens the door to gratitude for what Christ has done.

Pastor Voddie talked about how God requires perfect righteousness — perfect in our words, our thoughts, and our actions. Do you think anyone in our family, or anyone you know, has ever been perfect in all three of those things, even for one whole day? What happens when we realize we can't do it?

Grace Alone, Faith Alone—Together

  1. When you heard that justification is a gift we cannot earn, what stirred in your heart—relief, conviction, wonder, or something else?
  2. How do we subtly slip into earning God's favor in our marriage—through performance, conditional love, or unspoken debts—rather than resting in the grace that justifies us both?
  3. What is one area where your spouse needs to hear and believe that they are fully accepted in Christ, not because of what they do but because of what He has done—and how can you pray that truth over them this week?
Small-group discussion

6 questions for your group this week

  1. In Romans 3:21-26, Paul says righteousness comes apart from the law, yet the law and the prophets testify to it. What do you think Paul means by this apparent paradox, and why does he emphasize that this righteousness is revealed now?
    Romans 3:21
    → How does this help us understand why the Roman Catholic system of earning righteousness through works actually misses what Scripture itself has been pointing toward all along?
  2. The sermon emphasizes that the righteousness God requires means perfect law-keeping in word, thought, and deed—both inwardly and outwardly. When you honestly examine your own life, what does this standard reveal about your condition before God?
    Romans 3:22-23
    → Rather than trying to improve your record, what happens in your heart when you realize you cannot achieve this perfection on your own?
  3. Paul describes justification as a gift of grace (Romans 3:24). The sermon notes that if something is earned, it becomes wages rather than grace—there is nothing to boast about in receiving a gift. Why is this distinction so important for understanding what it means to be justified?
    Romans 3:24
    → Can you think of a time when you were tempted to take credit for your own spiritual progress, and what shifted your perspective back to grace?
  4. The sermon teaches that propitiation—God's wrath being satisfied—is central to justification. Looking at Romans 3:25-26 and the cross-reference in Isaiah 53:6, how does understanding that Christ bore God's wrath on our behalf change the way you see your own standing before God?
    Isaiah 53:6; Romans 3:25-26
  5. The doctrine of double imputation means Christ's perfect righteousness is credited to us, and our sin is imputed to Him on the cross. How does grasping this exchange—His active obedience for our failure, His passive suffering for our guilt—reshape your gratitude and your willingness to follow Him this week?
    2 Corinthians 5:21
    → What would it look like in a specific situation you're facing to respond to someone out of joy at this exchange rather than out of obligation?
  6. The sermon presents the five solas—grace alone, faith alone, Christ alone, Scripture alone, glory to God alone—as a unified whole, each protecting the others. Which of these solas do you find yourself most tempted to compromise, and what does that reveal about where you're still seeking righteousness apart from Christ?
