The central question of the Reformation. Are we justified by faith alone, or by a living faith that works in love and is perfected in perseverance?
63 verses are cited on this page. Each one links to its chapter in the Greek text.
For we account a man to be justified by faith, without the works of the law.Romans 3:28
The strongest text for the Protestant reading. The works Paul excludes are "the works of the law", the Mosaic observances and the boasting they bred. The word "alone" is not in the text, and Paul is contrasting faith with law-works, not with charity.
Because by the works of the law no flesh shall be justified before him. For by the law is the knowledge of sin.Romans 3:20
No one is justified by works of the law, which Catholic teaching has never denied. The law here is the Mosaic law under discussion throughout the chapter, and the reason given is that the law shows sin rather than removing it.
Now to him that worketh, the reward is not reckoned according to grace, but according to debt. But to him that worketh not, yet believeth in him that justifieth the ungodly, his faith is reputed to justice.Romans 4:1-5
The second pillar of the Protestant case, and the force of it should be felt: Paul says of the man who does not work that his faith is reckoned as justice, and the wage language is his own, misthos and opheilema, pay and debt. What the chapter is arguing is when Abraham was justified. He believed and it was reckoned to him before the law existed and before he was circumcised, which Paul presses at verses 9 to 10. The point is that justice was never a wage owed to law-keeping, not that the justified man is left without works: the same Abraham is the one James says was justified when he offered his son.
In the heart is belief unto righteousness, in the mouth is confession unto salvation.Romans 10:9-10
Paul names two acts, not one. Belief is interior, confession is spoken, and the mouth is part of the body. Even the text most often read as faith alone carries something more than assent inside it.
For by grace you are saved through faith... not of works, that no man may glory.Ephesians 2:8-9
Salvation is God's gift, not earned. The Catholic reading affirms this fully: grace is first and unmerited. The passage excludes works done to put God in one's debt, not the obedience of faith.
For we are his workmanship, created in Christ Jesus in good works, which God hath prepared that we should walk in them.Ephesians 2:10
The very next verse. We are saved by grace unto good works, which God has made the path we walk. Works are not the ground of the gift but its purpose.
...a man is not justified by the works of the law, but by the faith of Jesus Christ.Galatians 2:16
Again the contrast is faith against law-works, the same argument as Romans, not faith against a life of charity.
But Peter said to them: Do penance, and be baptized every one of you in the name of Jesus Christ, for the remission of your sins: and you shall receive the gift of the Holy Ghost.Acts 2:38
The first question asked after the first sermon is what must we do, and the answer is two imperatives, neither of them believe. Repent and be baptized, and the purpose given is eis aphesin, unto the forgiveness of sins. This is the apostolic gospel in its earliest recorded form.
For God so loved the world, as to give his only begotten Son; that whosoever believeth in him, may not perish, but may have life everlasting.John 3:16
The most quoted verse in the whole dispute, and the Church affirms every word of it. The believing it names is not bare assent: the same chapter puts believing against disobeying at verse 36, which is what the Greek there says.
He that heareth my word, and believeth him that sent me, hath life everlasting; and cometh not into judgment, but is passed from death to life.John 5:24
Present tense, has life, already passed over. The strongest form of the assurance argument. Note the sentence begins with hearing the word, and that in John hearing carries obeying, which is why the same chapter says the dead shall hear and come forth, some to a resurrection of judgment.
Believe in the Lord Jesus, and thou shalt be saved, and thy house.Acts 16:31
The plainest believe and be saved in the New Testament. Read the next verses: they preached to him, and he was baptized immediately, that same hour of the night. Luke gives believing and baptism in one motion, not belief instead of it.
Not having my justice, which is of the law, but that which is of the faith of Christ Jesus, which is of God, justice in faith.Philippians 3:9
The imputed righteousness text. What Paul contrasts is his own justice from the law against a justice from God through faith, which the Church affirms. Whether that justice stays outside a man or becomes really his is the question, and the verse does not settle it either way.
Thou believest that there is one God. Thou dost well: the devils also believe and tremble.James 2:19
Right assent to true doctrine is not saving faith; the demons have that and are lost. Faith that only affirms facts is not the faith that justifies.
So faith also, if it have not works, is dead in itself.James 2:17
A faith without works is not a lesser faith but a dead one, a corpse. Living faith and good works are not two things joined but one thing alive.
...but faith that worketh by charity.Galatians 5:6
Paul's own definition of the faith that avails: faith working through love. This is the Catholic formula in Paul's words.
...and if I should have all faith, so that I could remove mountains, and have not charity, I am nothing.1 Corinthians 13:2
Even mountain-moving faith without charity is nothing. Faith is not sufficient by itself; it must be informed by love.
Do you see that by works a man is justified; and not by faith only?James 2:24
The one place in Scripture where "faith" and "alone" appear together, and it denies the formula outright. This is the direct scriptural answer to a "faith alone" reading of Romans 3:28.
...for I was hungry, and you gave me to eat...Matthew 25:31-46
The great judgment scene sorts the sheep from the goats entirely by what they did and failed to do. Faith is presumed; deeds are the measure named.
Who will render to every man according to his works.Romans 2:6-7
Paul himself, in the same letter as Romans 3:28, says God judges by works. The two must be read together, not one against the other.
For not the hearers of the law are just before God, but the doers of the law shall be justified.Romans 2:13
Paul's own verb, dikaiothesontai, future passive, and the subject is the doers. This stands in the same letter as Romans 3:28, so any reading of faith alone has to hold both sentences at once rather than choosing one.
Not every one that saith to me, Lord, Lord, shall enter into the kingdom of heaven: but he that doth the will of my Father.Matthew 7:21
Confession of the Lord is not enough; doing the Father's will is the entrance.
Master, what good shall I do that I may have life everlasting? Who said to him: If thou wilt enter into life, keep the commandments.Matthew 19:16-17
The question is what must I do, and Christ does not correct the framing. He answers it. Whatever else justification requires, the first answer given to the first man who asked was the commandments.
Master, what must I do to possess eternal life? Thou hast answered right: this do, and thou shalt live.Luke 10:25-28
Asked again, answered the same way. Love God and love your neighbour, and then do this and you shall live. The verb is imperative and the promise is attached to it.
And being consummated, he became, to all that obey him, the cause of eternal salvation.Hebrews 5:9
The cause is Christ and nothing else. But the sentence names who receives it, and the word is hypakouousin, those obeying him. Salvation is caused by one and applied to the obedient.
For we must all be manifested before the judgment seat of Christ, that every one may receive... according as he hath done.2 Corinthians 5:10
Judgment is according to what each has done in the body, good or evil.
But he that shall persevere to the end, he shall be saved.Matthew 24:13
Salvation is promised to the one who endures to the end, not secured at a single moment past.
...with fear and trembling work out your salvation.Philippians 2:12
Salvation is worked out, an ongoing labor, held in reverent fear, not a finished transaction.
Take heed, brethren, lest perhaps there be in any of you an evil heart of unbelief, to depart from the living God. For we are made partakers of Christ: yet so, if we hold the beginning of his substance firm unto the end.Hebrews 3:12-14
Addressed to brethren, not to outsiders, and the danger named is departing from the living God. Partakers of Christ is stated as a present fact and then made conditional on holding firm to the end. The warning has no force if the outcome were already secured.
And we see that they could not enter in, because of unbelief.Hebrews 3:19
The wilderness generation is the writer's worked example throughout the chapter. They were brought out, and they did not enter. That is the shape of the warning he is making to Christians.
For it is impossible for those who were once illuminated... and are fallen away, to be renewed again to penance.Hebrews 6:4-6
Those truly enlightened can fall away. The warning has no force if the saved cannot be lost.
For if we sin wilfully after having the knowledge of the truth, there is now left no sacrifice for sins, but a certain dreadful expectation of judgment.Hebrews 10:26-27
A grave warning to believers, not to outsiders, that wilful sin after receiving the truth imperils salvation.
You are made void of Christ... you are fallen from grace.Galatians 5:4
One can fall from grace, which cannot happen to what was never held.
But I chastise my body... lest perhaps, when I have preached to others, I myself should become a castaway.1 Corinthians 9:27
Even Paul does not presume his own salvation is beyond loss.
Know you not that the unjust shall not possess the kingdom of God?... shall possess the kingdom of God.1 Corinthians 6:9-10
A named catalogue of sins that shut a person out of the kingdom. The barrier is unrepented sin, not lack of belief.
...they who do such things shall not obtain the kingdom of God.Galatians 5:19-21
Another list of the works of the flesh with the same verdict: those who do them do not inherit the kingdom.
...no fornicator, or unclean, or covetous person... hath inheritance in the kingdom of Christ and of God.Ephesians 5:5-6
The same exclusion, with a warning against being deceived by empty words that say otherwise.
...I never knew you: depart from me, you that work iniquity.Matthew 7:21-23
Those who prophesied and worked wonders in Christ's name are still cast out for working iniquity.
It is a fearful thing to fall into the hands of the living God.Hebrews 10:26-31
The wilful sinner tramples the Son of God and faces judgment, not mercy presumed.
But the fearful, and unbelieving... shall have their portion in the pool burning with fire and brimstone.Revelation 21:8
The unbelieving and the sinner alike named among those whose portion is the second death.
Scripture never says "faith alone" except to deny it (James 2:24). We are justified by grace as a free gift, received through faith, and that faith is living only as it works through charity (Galatians 5:6). Justification is a true inner renewal that grows through good works and can be lost through grave sin and regained through penance. The Council of Trent (Session 6) defined this: grace is unmerited and faith is its beginning, yet justification increases through the works faith produces, and it is forfeited by mortal sin. Faith and works are not rivals. A dead faith saves no one, and a living faith cannot help but work.
