The question behind every religion

Every religion must answer: how can a sinful person be right with a holy God? The answers fall into two families. Either God accepts us, in whole or in part, because of something we do or become, or God accepts us entirely because of what someone else has done for us. The biblical gospel is the second. That is why justification is the dividing line between Christianity and every alternative.

Martin Luther reportedly called justification the article on which the church stands or falls. Whether or not he used those exact words, the Reformers all treated it that way, and so should you. You learned the doctrine in Know Your Faith, Lesson 7; this lesson defends it. Note that this is not a Calvinist-versus-Arminian issue. Evangelicals who are not Calvinists confess it just as firmly: the Methodist Articles of Religion (Article IX) say we are 'accounted righteous before God only for the merit of our Lord and Saviour Jesus Christ by faith'.

What are the two families of answers to 'How can a sinful person be right with a holy God?', and why is justification the dividing line?Show answer

Either God accepts us, in whole or in part, because of something we do or become, or he accepts us entirely because of what someone else has done for us. The biblical gospel is the second. Because every religion must answer this question, justification separates Christianity from every alternative.

Something we do or become
Entirely what another did
Gospel is the second
Divides from all alternatives

Recap: the key terms

State the terms precisely before you defend them (Know Your Faith, Lesson 7, treats each in full).

Justification is a legal declaration by God that a sinner is righteous in his sight. It is a verdict, not a process of moral improvement. Its opposite in Scripture is 'condemn' (Deut 25:1; Rom 8:33-34), which shows it is courtroom language.

Imputation means crediting something to someone's account. Our sin is credited to Christ, and Christ's perfect righteousness is credited to us (2 Cor 5:21). God does not pretend we are good; he counts Christ's real goodness as ours because we are united to him by faith.

Sanctification is the lifelong work of the Spirit making us actually holy. It always follows justification and is never its ground. Confusing the two is the root of most errors on this subject.

Faith is not a work that earns anything. It is the empty hand that receives a gift: knowing the gospel, agreeing it is true and personally trusting Christ.

What is the difference between justification and sanctification, and why does the difference matter?Show answer

Justification is a legal declaration, a verdict that a sinner is righteous in God's sight, not a process. Sanctification is the lifelong work of the Spirit making us actually holy; it always follows justification but is never its ground. Confusing the two is the root of most errors on this subject.

Justification = verdict
Sanctification = process
Sanctification follows, not ground
Confusion causes errors

Explain imputation and the role of faith in your own words.Show answer

Imputation means crediting something to someone's account: our sin is credited to Christ, and his perfect righteousness is credited to us (2 Cor 5:21). God is not pretending we are good; he counts Christ's real goodness as ours because we are united to him by faith. Faith earns nothing; it is the empty hand that receives the gift by knowing the gospel, agreeing it is true and trusting Christ.

Crediting to an account
Double exchange (2 Cor 5:21)
Not pretending
Faith = empty hand

Romans 3-5, Galatians 2 and Ephesians 2

In Romans 1:18-3:20 Paul shows that Gentiles and Jews alike are under sin: 'None is righteous, no, not one' (3:10). Then comes the turn: 'But now the righteousness of God has been manifested apart from the law' (3:21), received 'through faith in Jesus Christ for all who believe'. We are 'justified by his grace as a gift, through the redemption that is in Christ Jesus' (3:24), whom God put forward as a propitiation, a sacrifice that turns away wrath. God is both just and the justifier of the one who has faith in Jesus (3:26). Paul concludes that a person is justified by faith apart from works of the law (3:28).

Romans 4 uses Abraham, who was counted righteous by believing God before he was circumcised (4:3, 10). Verses 4-5 are decisive: to the one who works, wages are owed; but to the one who does not work but believes in him who justifies the ungodly, his faith is counted as righteousness. Romans 5:1 gives the result: peace with God. Romans 5:12-21 grounds imputation in our union with Adam and with Christ.

Galatians 2:16 says three times in one verse that no one is justified by works of the law but through faith in Christ. Ephesians 2:8-9 says salvation is by grace through faith, 'not a result of works, so that no one may boast', and verse 10 adds that we are created for good works. Works are the fruit, not the root.

Which verse in Romans 4 does the lesson call decisive, and what does it show?Show answer

Romans 4:4-5 contrasts the one who works, to whom wages are owed, with the one who does not work but believes in him who justifies the ungodly. That person's faith is counted as righteousness. It shows that justification is a gift received by faith, not a wage earned by works, and Abraham himself was counted righteous by believing before he was circumcised.

Romans 4:4-5
Wages vs gift
God justifies the ungodly
Abraham before circumcision

How do Ephesians 2:8-10 and Galatians 2:16 together show the place of good works?Show answer

Galatians 2:16 says three times that no one is justified by works of the law but through faith in Christ. Ephesians 2:8-9 says salvation is by grace through faith, not by works, so no one may boast, and verse 10 adds that we are created for good works. Works are the fruit of salvation, not its root.

Not justified by works (Gal 2:16)
Grace through faith, no boasting
Created for good works
Fruit, not root

James 2 answered

James 2:24 says 'a person is justified by works and not by faith alone'. Is this a contradiction? Read the context. James is addressing someone who 'says he has faith' (2:14) but has no works, a faith that only wishes a hungry brother well (2:15-16). His question is 'Can that faith save him?' The answer is no. Dead faith, mere intellectual agreement, is the faith demons have (2:19).

James uses 'justified' in the sense of 'shown to be righteous' or vindicated, as when Jesus says wisdom is justified by her deeds (Matt 11:19). Abraham was declared righteous by faith in Genesis 15:6, but that faith was shown to be real decades later when he offered Isaac in Genesis 22. Paul asks, 'How is a sinner made right with God?' James asks, 'How is a true believer shown to be real?' Paul fights legalism; James fights empty profession. The Reformers summed it up: we are justified by faith alone, but the faith that justifies is never alone.

How would you explain to a friend why James 2:24 does not contradict Paul?Show answer

James is addressing someone who says he has faith but has no works, a dead faith like that of demons (2:14-19). He uses 'justified' to mean shown or vindicated as righteous, as Abraham's faith was shown real when he offered Isaac. Paul asks how a sinner is made right with God; James asks how a true believer is shown to be real. We are justified by faith alone, but the faith that justifies is never alone.

Context: dead, claimed faith
'Justified' = shown righteous
Different questions
Faith never alone

'Luther invented faith alone'

A common Roman Catholic objection: 'The Bible says "faith alone" only in James 2:24, which denies it, and Luther added "alone" to Romans 3:28.'

Be honest about the facts. Luther did add allein ('alone') to Romans 3:28 in his German Bible, and he openly defended it in On Translating: An Open Letter (1530). He admitted the word is not in the Greek, but argued that natural German needs 'alone' to say plainly what Paul's sentence already means.

Then move from the word to the teaching. Paul says a person is justified by faith 'apart from works of the law' (Rom 3:28), that righteousness is counted 'to the one who does not work but believes' (Rom 4:5), and that we are 'not justified by works of the law but through faith in Jesus Christ' (Gal 2:16). If every work is excluded as the ground, faith is the only instrument left. That is all 'faith alone' means. James 2:24 rejects only a dead faith, as the previous section showed. The Reformers claimed to recover the apostles' gospel, not to invent a new one (see The Story of the Church, Lesson 5).

How would you answer the claim that sola fide is Luther's invention because he added 'alone' to Romans 3:28?Show answer

Admit the fact: Luther added 'allein' to Romans 3:28 in his German Bible and defended it in On Translating (1530), saying German needs the word to express Paul's meaning. Then move from the word to the teaching. Paul says we are justified 'apart from works of the law' (Rom 3:28), counted righteous as 'the one who does not work but believes' (Rom 4:5), and 'not justified by works of the law but through faith' (Gal 2:16). If works are excluded as the ground, faith is the only instrument left, and James 2:24 rejects only a dead faith.

Honest about Luther's translation
Word vs teaching
Rom 3:28; 4:5; Gal 2:16
Works excluded, faith alone remains
James 2:24 = dead faith

Why this is the dividing line

Treat these sources fairly: each tradition speaks of grace, and many of its members sincerely love God. The issue is whether grace plus our contribution, or grace alone through faith alone, is the ground of our standing before God. Each has its own module later in the course; here you need only the outline.

Roman Catholicism. The Council of Trent (Session 6, 1547) taught that justification includes inner renewal, is first received in baptism, can be increased by good works (Canon 24) and lost by mortal sin. Canon 9 anathematises anyone who says the ungodly is justified by faith alone in the sense that nothing else is required to cooperate. The Catechism (CCC 1987-1995, 2010) presents justification as infused righteousness bound up with sanctification.
Mormonism. 2 Nephi 25:23 says 'it is by grace that we are saved, after all we can do', and the Third Article of Faith speaks of salvation through the Atonement 'by obedience to the laws and ordinances of the Gospel'. Exaltation requires temple ordinances and covenant faithfulness. Many Latter-day Saint leaders today stress that no one can earn heaven and that grace is needed at every stage (for example, Dieter F. Uchtdorf, 'The Gift of Grace', April 2015 general conference), but obedience to ordinances remains required for exaltation.
Islam. There is no atonement by another; deeds are weighed on the scales (Quran 7:8-9; 23:102-103; 101:6-9), and no bearer of burdens bears another's burden (6:164; 35:18). Hope rests on God's mercy and one's deeds.
The Watchtower. The Watchtower of 15 February 1983 (pp. 12-13) listed requirements for everlasting life including taking in knowledge, obeying God's laws, associating with God's organisation and loyally telling others. Ransom is the basis, but faithful works within the organisation are required.

According to the lesson, what is the real issue between the biblical gospel and these other traditions, given that they all speak of grace?Show answer

Each tradition speaks of grace, and many members sincerely love God, so we should treat them fairly. The issue is whether grace plus our contribution, or grace alone through faith alone, is the ground of our standing before God. That is the question to keep in focus.

Treat fairly
All speak of grace
Grace plus contribution vs grace alone
Ground of standing

Choose two of the four traditions described and explain what each adds to faith as a requirement for salvation.Show answer

Trent taught that justification includes inner renewal, is received in baptism, can be increased by good works and lost by mortal sin. Latter-day Saint teaching says we are saved by grace 'after all we can do', and exaltation requires temple ordinances and obedience. In Islam deeds are weighed on the scales with no atonement by another, and the Watchtower lists requirements such as obeying God's laws and associating with God's organisation.

Names two traditions accurately
Rome: renewal, works, mortal sin
LDS: ordinances; Islam: scales
Watchtower: organisational works

Bringing it to people

When talking with someone from these groups, do not open with 'Your church is wrong'. Ask, 'If you died tonight, how confident are you that God would accept you, and on what basis?' Most will answer with some mix of faith and effort and admit they cannot be sure. Then show Romans 4:5: God justifies the ungodly, the one who does not work but believes. Assurance (Rom 5:1; 8:1; 1 John 5:13) is one of the most attractive features of the true gospel for people who are worn out from trying.

Do not stop at the argument. Call them, as the apostles did, to turn from sin and from trust in their own record and to trust Christ alone (Mark 1:15; Acts 20:21). Tactics and Debate, Lesson 5, shows how to bring any conversation to this point.

What question does the lesson suggest asking someone from these groups, and why is assurance attractive?Show answer

Ask, 'If you died tonight, how confident are you that God would accept you, and on what basis?' Most will answer with a mix of faith and effort and admit they cannot be sure. Then show Romans 4:5, that God justifies the one who does not work but believes. Assurance (Rom 5:1; 8:1; 1 John 5:13) is deeply attractive to people worn out from trying.

Don't open with 'You're wrong'
Ask confidence and basis

Assurance for the weary

Why does the lesson say you should not stop at the argument, and what call should follow?Show answer

Winning the point about justification is not the goal; the person needs Christ. So, as the apostles did, call them to turn from sin and from trust in their own record and to trust Christ alone (Mark 1:15; Acts 20:21).

Argument is not the goal
Repent: turn from sin and self-trust
Believe: trust Christ alone

In their own words

“If any one saith, that by faith alone the impious is justified; in such wise as to mean, that nothing else is required to co-operate in order to the obtaining the grace of Justification ... let him be anathema.” (Council of Trent, Session 6, Canon 9 (13 January 1547; Waterworth translation))

“No one can merit the initial grace of forgiveness and justification; but, moved by the Holy Spirit and by charity, we can then merit for ourselves and for others the graces needed for our sanctification, for the increase of grace and charity, and for the attainment of eternal life.” (Catechism of the Catholic Church 2010 (paraphrased))

“It is by grace that we are saved, after all we can do.” (Book of Mormon, 2 Nephi 25:23)

“Those whose scales are heavy with good deeds will be successful; those whose scales are light will have lost their souls.” (Quran 23:102-103 (paraphrased))

“Everlasting life requires taking in knowledge, obeying God's laws, being associated with God's channel (the organisation) and loyally advocating God's Kingdom.” (The Watchtower, 15 February 1983, pp. 12-13 (summarised))

Key texts

Romans 3:21-28: The thesis of the gospel: righteousness from God apart from the law, received by faith, grounded in Christ's propitiation.
Romans 4:4-5: Works earn wages; faith receives a gift. God justifies the ungodly. Use this when someone mixes grace and works.
2 Corinthians 5:21: The great exchange: our sin to Christ, his righteousness to us. The clearest text for double imputation.
Galatians 2:16: Three times in one verse, Paul denies justification by works of the law.
Ephesians 2:8-10: By grace, through faith, not of works, yet created for good works. Holds root and fruit together.
James 2:14-26: Real faith is shown by works; James is answering empty profession, not teaching works as the ground of justification.
Philippians 3:8-9: Paul abandons a righteousness of his own from the law for the righteousness from God that depends on faith.

Objections and answers

Try answering each one yourself before you open the response.

“James 2:24 literally says 'not by faith alone'. You Protestants ignore it.”Show a response

We take James seriously, so let's read the whole paragraph. James is testing a claimed faith that has no works (2:14), the kind demons have (2:19). He uses 'justified' as Jesus does in Matthew 11:19: shown to be right. His proof is Abraham offering Isaac in Genesis 22, decades after God had already counted him righteous in Genesis 15:6. So James is asking how genuine faith is demonstrated, while Paul in Romans 4 is asking how the ungodly are declared righteous before God. Both use Abraham, both quote Genesis 15:6, and neither contradicts the other. Saving faith is never alone, but it is faith alone that receives Christ's righteousness. A faith that produces nothing was never saving faith.

“If we're saved by faith alone, you can just pray a prayer and then live however you want.”Show a response

Paul anticipated this exact objection: 'Are we to continue in sin that grace may abound? By no means!' (Rom 6:1-2). The faith that justifies unites us to Christ, and union with Christ means new life. The same God who declares us righteous also gives us a new heart and his Spirit (Ezek 36:26-27; Eph 2:10). So the Reformed position is not 'faith without works' but 'faith that works, with works not counted as the ground of our acceptance'. If someone claims faith yet loves sin without any struggle or change, Scripture tells them to examine themselves (2 Cor 13:5). Grace does not make holiness optional; it makes holiness possible and joyful.

“Catholics also believe in grace. Trent says we can't earn initial justification. You're attacking a straw man.”Show a response

That's a fair correction, and we should represent Rome accurately. Trent (Session 6, chapter 8) does say nothing that precedes justification, whether faith or works, merits the grace of justification. The disagreement is about what justification is and what keeps it. For Rome, justification is the infusion of righteousness, begun in baptism, increased by good works (Canon 24), lost by mortal sin and restored through penance. For the Reformers, justification is a once-for-all legal verdict based on Christ's imputed righteousness, received by faith alone. So the question is not grace versus no grace but whether my standing before God rests on Christ's righteousness alone or on Christ's grace working with my cooperation. Paul's 'to the one who does not work but believes' (Rom 4:5) settles it.

“A good God would weigh my good deeds against my bad. Why would he need a sacrifice at all?”Show a response

Imagine a judge who let a man who had committed a serious crime go free because he had also done many kind things. We would call that judge corrupt, not good. A just God cannot simply ignore evil (Prov 17:15). Good deeds are what we already owe, so they cannot pay off a debt. That leaves two options: we bear the penalty ourselves, or someone qualified bears it for us. The gospel says God himself, in the person of the Son, took our place, so that he is 'just and the justifier' (Rom 3:26). The cross is how God can be both perfectly fair and perfectly merciful. A scales system offers no assurance; the cross offers peace (Rom 5:1).

“Imputation sounds like a legal fiction. If God declares me righteous when I'm not, isn't he just pretending?”Show a response

That would be a serious problem, but it is not what Scripture teaches. God does not pretend we are good. He counts Christ's real, perfect righteousness as ours because we are united to Christ by faith, just as our real sin was counted to him: 'For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God' (2 Cor 5:21). Nothing fictional happens. A real penalty was paid and a real obedience was credited. Romans 4:5 is bold about this: God 'justifies the ungodly'. And the verdict is never the end of the story. Everyone God justifies, he also begins to make actually holy through sanctification. The verdict comes first and the transformation follows, but both are real.

“If I have to believe to be saved, then believing is something I do. So faith is just another work, and you're saved by your own effort too.”Show a response

It's a good question, and Paul answers it by setting faith against works rather than counting it as one. 'To the one who works, his wages are not counted as a gift but as his due. And to the one who does not work but believes in him who justifies the ungodly, his faith is counted as righteousness' (Rom 4:4-5). Faith is not the thing that earns; it is the empty hand that receives. A beggar who holds out his hand for bread does not boast that he earned the meal. That is why Ephesians 2:8-9 can say we are saved through faith, 'not a result of works, so that no one may boast'. The value is all in the one trusted, Christ, not in the trusting.

Written task

Your Catholic friend says: 'We both believe in grace and faith. The only difference is that we don't think faith is alone, because James 2:24 says so. Why does this matter so much to you?' Write a 300-400 word answer that represents Catholic teaching fairly, using at least one Trent canon or Catechism paragraph, explains James 2 in context, and shows why the difference matters for assurance and for the glory of Christ.

Hand this in to Mr Scott. He will look for:

Accurately and charitably states Catholic teaching with a correct citation
Defines justification and imputation clearly
Explains James 2 in context, including the use of 'justified' and the Abraham example
Uses Romans 4:4-5 or Galatians 2:16 accurately
Explains the practical stakes (assurance, boasting, Christ's sufficiency) with a warm tone
