Sola Fide

Question 1

If someone asked you, “What must I do to be saved?” how would you answer? Notice the assumptions embedded in the word “do.” The Philippian jailer asked Paul this exact question (Acts 16:30–31). Paul’s answer was not a list of actions but a single verb: “Believe.” What is the difference between answering with a set of requirements and answering with a promise to be trusted?

Question 2

The Apology of the Augsburg Confession distinguishes three components of faith: knowledge (notitia), assent (assensus), and trust (fiducia). Can you have one or two of these without the third? Consider: a person who knows the facts of the Gospel but does not trust Christ personally has notitia and perhaps assensus but lacks fiducia. James 2:19 says even the demons “believe” in that sense. On the other side, a person who claims to trust Jesus but rejects the content of the Gospel has feeling without knowledge. How does this threefold definition protect against errors on both sides?

Question 3

Paul uses the verb logizometha (“we conclude/reckon”), a term from the world of accounting and law. He is not offering a personal opinion; he is rendering an apostolic verdict. The same verb, when God is its subject in Romans 4, means to “credit” righteousness to someone’s account. How does Paul’s choice of this accounting term shape the way we should understand justification? Is justification a process of moral improvement or a legal declaration?

Question 4

Romans 3:28 is the only verse in the New Testament where the simple dative pistei (“by faith”) appears directly with the verb “to justify” (dikaioō). Everywhere else Paul uses prepositions: “through faith” (dia pisteōs) or “from faith” (ek pisteōs). The bare dative emphasizes faith as the sheer means or instrument. Why does this grammatical distinction matter? How does it reinforce the teaching that faith is the empty hand that receives rather than a meritorious act that earns?

Question 5

Luther famously translated Romans 3:28 with the word allein (“alone”): “a person is justified by faith alone, apart from works of the law.” His critics attacked him for adding a word not in the Greek. The Apology defends this by pointing to the exclusive particles in the text (“apart from,” “as a gift,” “not of works”). When you have a stark either/or contrast—“by faith” set directly against “apart from works”—does the grammar demand the word “alone,” even if it is not literally present? Is Luther’s addition a distortion of Paul or an accurate rendering of Paul’s logic?

Question 6

In verses 4–5, Paul draws a sharp economic contrast. The worker receives wages as something owed (kata opheilēma, “according to debt”); the believer receives righteousness as a gift of grace (kata charin, “according to grace”). If salvation involved our works, God would owe us—which would destroy the very concept of grace. How does this workplace metaphor clarify the difference between faith and works? Why is it important that the relationship between God and the justified sinner is not one of employer and employee?

Question 7

Verse 5 contains one of the most shocking statements in Scripture: God “justifies the ungodly” (ton asebē). The word asebēs means “irreverent, impious.” First-century Jewish tradition taught that Abraham was “perfect in all his deeds with the Lord” (Jubilees 23:10). Paul overturns this: Abraham was not justified because he was godly; he was an ungodly man whom God declared righteous. How does this verse shatter every system that conditions God’s verdict on the sinner’s prior moral improvement?

Question 8

Paul links Abraham (Genesis 15:6) to David (Psalm 32:1–2) through the exegetical technique known as gezerah shawah: both texts share the verb logizomai / hashab (“to count, to reckon”). David pronounces a blessing on the person to whom God “counts righteousness apart from works” (v. 6) and against whom the Lord “will not count his sin” (v. 8). Justification thus has two sides: the crediting of Christ’s righteousness and the non-counting of the sinner’s guilt. Why are both sides necessary? What would be missing if God forgave sin but credited no positive righteousness?

Question 9

In verse 16, Paul makes the same point three times: justified not by works of the law but through faith in Christ. Why does he repeat it with such force? The Galatian false teachers were not denying Christ; they were adding requirements to faith in Christ. Is the addition of even one human requirement to the Gospel a minor modification or a fundamental destruction of it? How does verse 21 (“if righteousness were through the law, then Christ died for no purpose”) settle the question?

Question 10

Paul quotes Psalm 143:2 in verse 16 but makes a deliberate alteration: where the Psalm says “no living being,” Paul substitutes “all flesh” (pasa sarx) and inserts the phrase “by works of the law.” Why does Paul tighten and intensify the Old Testament text? What does sarx (“flesh”) convey that “living being” does not? How does this alteration serve Paul’s argument that the Law cannot save?

Question 11

Verse 20 is the personal confession at the heart of Sola Fide: “I have been crucified with Christ. It is no longer I who live, but Christ who lives in me.” This is not a contradiction but a profound duality. The old “I” governed by the Law and the flesh is dead; Christ is now the source of life. Paul then says the life he now lives in the flesh, he lives “in faith” (en pistei) in the Son of God. How does the concept of being “crucified with Christ” relate to justification by faith? Is Paul describing an experience the believer achieves, or a reality the believer receives in baptism (cf. Romans 6:3–4)?

Question 12

Verse 21 contains the devastating conclusion: “I do not nullify (atheteō) the grace of God, for if righteousness were through the law, then Christ died for nothing (dōrean).” The verb atheteō means to render ineffective or to reject. Every system that conditions righteousness on human obedience renders the cross purposeless. How does this verse serve as a test for evaluating any proposed addition to the Gospel? If someone says, “You must believe in Christ and do X in order to be saved,” what has happened to grace?

Question 13

In verse 14, James asks: “Can that faith save him?” The Greek includes the anaphoric definite article hē, which points backward to the faith he has just described: a mere verbal claim with no deeds. James is not questioning whether genuine, Christ-clinging faith saves. He is exposing a counterfeit. How does this grammatical observation change the way you hear the passage? What is the difference between saying “faith cannot save” and saying “that kind of faith cannot save”?

Question 14

James says even the demons “believe and shudder” (phrissousin, v. 19). The demons possess accurate theology: they know God is one. Yet their “faith” produces not trust but terror. The Apology’s threefold definition of faith (notitia, assensus, fiducia) is directly relevant here. The demons have knowledge and assent but utterly lack trust. How does James’s argument reinforce the Confessional insistence that saving faith is not merely intellectual agreement but personal, clinging trust in Christ’s promise?

Question 15

James 2:24 says, “A person is justified by works and not by faith alone.” Paul says, “A person is justified by faith apart from works of the law” (Romans 3:28). The Confessions resolve this not by pitting one apostle against the other but by distinguishing two different questions. Paul answers: on what basis does God declare a sinner righteous? (Answer: by faith, coram Deo.) James answers: how is genuine faith distinguished from counterfeit faith? (Answer: by its fruits, coram mundo.) In your own words, explain this distinction. What goes wrong if you read James as answering Paul’s question or Paul as answering James’s question?

Question 16

James says Abraham’s faith “was completed” (eteleiothē) by his works (v. 22). The passive voice is significant: God brought Abraham’s faith to its designed goal through his obedient actions. Notice: James does not say Abraham’s faith was created by works or earned its justifying power through works. Genesis 15:6 had already declared Abraham righteous decades before the offering of Isaac in Genesis 22. The works completed what was already a living, justified faith. How does the sequence of Genesis 15 and Genesis 22 protect against reading James as teaching works-righteousness?

Question 17

James’s closing analogy in verse 26 is devastating: “As the body apart from the spirit (pneuma) is dead, so also faith apart from works is dead.” Just as the absence of breath proves a body is a corpse, the absence of good works proves that a “faith” is a spiritual corpse. The Reformers summarized it this way: “We are justified by faith alone, but the faith that justifies is never alone.” Does this analogy teach that works contribute to justification, or that works are the vital sign of a faith that is already alive? What is the difference?

Question 18

Jesus says the Son of Man “must” (dei) be lifted up (v. 14). This word signals divine necessity—God’s unalterable plan. The verb “lifted up” (hypsōthēnai) carries a double meaning in John: physical lifting on the cross and exaltation in glory. The cross is the glory. How does this double meaning shape our understanding of saving faith? What does faith look to: a defeated victim or an exalted Savior? The answer, according to John, is both at once.

Question 19

The bronze serpent typology (Numbers 21:4–9) is the image Jesus Himself chose to explain the nature of faith. The Israelites were dying; they could do nothing to cure themselves; they could only look to the serpent on the pole and live. The Formula of Concord says faith justifies “not because it is so good a work and so God-pleasing a virtue, but because it lays hold on and accepts the merit of Christ” (FC Ep III, §13). How does the serpent image protect against treating faith itself as a meritorious act? What is the difference between “faith saves because of its quality” and “faith saves because of its object”?

Question 20

Verse 18 sets up an absolute dichotomy: “whoever believes in him is not condemned (ou krinetai), but whoever does not believe is condemned already (ēdē kekritai).” The perfect tense kekritai indicates a settled, continuing state. The verdict of acquittal or condemnation is rendered now, not at some future tribunal. How does this present-tense assurance relate to Sola Fide? If justification is a completed verdict for the believer, what does this do to the terrified conscience that asks, “Am I saved?”

Question 21

Article IV says believers are justified “when they believe that they are received into grace and that their sins are forgiven on account of Christ.” The content of faith is specified: it is not a generic religious feeling but a specific trust that God is gracious to me for Christ’s sake. Luther’s explanation of the Second Article is intensely personal: “my Lord” who has redeemed “me.” How does Sola Fide move from an abstract doctrine to a personal confession? What is the difference between saying “Christ is the Savior” and “Christ is my Savior”?

Question 22

Article VI declares that faith “is bound to bring forth good fruits” and that good works “must” be done “because it is God’s will.” Yet the article adds the critical qualifier: “not because we rely on such works to merit justification.” The tree produces fruit; the fruit does not produce the tree. How does this article prevent the antinomian misreading of Sola Fide (that is, the claim that since faith alone justifies, good works do not matter)? Where do you see this misreading at work today?

Question 23

The Formula of Concord says faith justifies “not because it is so good a work and so God-pleasing a virtue, but because it lays hold on and accepts the merit of Christ” (FC Ep III, §13). Why does it matter that faith is classified as an instrument rather than a virtue? If faith justified because of its quality (its intensity, its sincerity, its depth), where would the troubled conscience look for assurance: to the strength of its own believing or to the merit of Christ? How does the instrument/virtue distinction protect the Gospel?

Question 24

We have now established the authority (Sola Scriptura), the source (Sola Gratia), and the instrument (Sola Fide). Next week we turn to Solus Christus—the material center around which all the other solas orbit. If grace is the source and faith is the instrument, then Christ is the object of faith and the ground of justification. If you had to explain Sola Fide in one sentence to someone who had never heard of it, what would you say?

Question 25

Someone says: “I believe in God, but I don’t think it matters which church you go to or what you believe about the details.” How does the Confessional understanding of faith as having content (notitia), assent (assensus), and trust (fiducia) respond to this claim? Can faith exist without specific doctrinal content? What happens to fiducia when notitia is removed?

Question 26

Luther wrote in his Preface to Romans (1522): “Faith is a living, daring confidence in God’s grace, so sure and certain that the believer would stake his life on it a thousand times. This knowledge of and confidence in God’s grace makes a person glad, bold, and happy in dealing with God and all creatures.” As we close this session and prepare for Solus Christus next week, how does the doctrine of Sola Fide shape the way you approach God in prayer, receive the Lord’s Supper, and face the afflictions of daily life? What is one concrete way you could take the “alone” in “faith alone” more seriously this week?
