"Faith Alone"?

If you have heard the term "Protestant" before, chances are you have also heard the saying "faith alone." The way Protestants speak of "faith alone" might almost give one the impression that Luther and his band of rebels chanted this mantra all the way out of the Catholic cathedral as they defected from the Mother Church and set off to seek a better way.

So what is the story on this "faith alone" concept? As a Protestant, the first place I go when I have questions is Scripture. ("Sola Scriptura," right?) When I do a query in the NASB Bible on "faith alone" this is the only entry that comes up:

You see that a man is justified by works and not by faith alone. -James 2:24

That is humorous. (Of course, from what I am told, Luther did not believe that the book of James belonged in the canon of Scripture anyway... but I digress.)

So where did the idea of "faith alone" come from? From what I understand, Luther had translated the following verse into Latin, at which point the Catholic church back-translated it into German, incorrectly rendering the bolded term as "faith alone":

For we maintain that a man is justified by faith apart from works of the Law. -Romans 3:28

So the Catholics rendered the Latin as "faith alone apart from works of the Law," and were outraged. However, Luther maintained that the Catholics had mistranslated his Latin, and that the Latin solum ("alone") was necessary in Latin to convey the meaning of the sentence, though they were correct that the extra term was unnecessary in German. So in Luther's mind, the Latin was accurate with solum ("alone"), and the German was accurate without allein ("alone"). All that to say it seems that in Luther's mind "faith alone" was nothing more than a Catholic mistranslation! So how did it become a Protestant mantra?!

To further complicate matters, Romans 3:28 does not contrast faith with works, but with works of the Law; i.e. the Mosaic Law. Yet the modern Protestant mantra seems to contrast faith with any sort of action.

My Question

So, can someone explain the Protestant doctrine of "faith alone" to me? Do I have my facts straight about its origin (a Catholic mistranslation from Latin to German)? If so, how in the world did a Catholic mistranslation (that Luther rejected) become a Protestant mantra?!

Also, is this doctrine really as foundational to Protestantism as people think it is? And what does this doctrine even mean? Is it "faith apart from any action"? Is it "faith apart from the Mosaic Law"? Something else? Would Luther even affirm the Protestant doctrine of "faith alone"?

Related: What is the biblical basis for salvation by faith alone (sola fide)? This question asks how a person would justify this doctrine from Scripture. It's not the same as what I'm asking here, but it is relevant none the less.

Also related: Can someone help me cite Luther's explanation of faith alone to Catholics? This question asks for a particular source to use in an upcoming blog post. Not at all what I'm asking, but related none the less.

  • I was going to look up the answer to that question I wrote last year. Did you look at my answer to the question. I didn't find myself agreeing with Mike's assessment so I looked it up myself. – Peter Turner Jul 9 '13 at 2:46
  • While I'm not sure the average Christian approaches the terminology with any real subtly, I'm under the impression from a Peter Kreeft video I saw (which, if I find again I'll post in an answer) that the verses used to support sola fida refer to a "broad faith" that's more synonymous with religion than the verses Catholics use for faith and works, in which a "narrow faith" is intended, more synonymous with trust. And if memory serves, Kreeft was speaking out of turn on this, but drawing on the outcome of an interfaith dialogue. ... I'll try to dig that up. – svidgen Jul 9 '13 at 3:15

The correct understanding of this term is so fundamental in understanding the reformation. It certainly has nothing to do with linguistics or translations. It has everything to do with the doctrine of justification. There are only two sides to the issue. Catholics (and I believe Eastern Orthodox and the Syrian Churches) do not believe in a momentary or instantaneous justification occurring when we are still God's enemies. They believe in justification as something requiring ‘our cooperation’ with grace (code word for works from a Protestant view) until we are finally justified in the final judgment...based on our ‘cooperation’ with grace. Luther and the reformers thought this was all pure and wicked nonsense. They believed in justification that occurs in a moment, while we have no works but only sin. In other words, while a sinner has no merits, no works (all moral goodness are considered the works of the Law as it is the law that requires them) he is justified forever. No merits whatsoever of any kind only a sinful heart forgiven when a person is made justified in an instant. The only condition is faith but not the active kind, rather the passive reception of a gift, excluding justifying faith as a work also. This has often been called 'an alien righteousness' because it is Christ's righteousness imputed to sinners apart from any of their own internal holiness. It is alien to our inner experience.

In simple terms ‘faith apart from works’ means we are justified in 'a moment' while we have no works to consider at all, i.e. justified apart from anything of the sort. Either we are justified over a period of time, where our obedience and personal holiness and sins are taken into the equation, i.e. ‘justified with works in the equation’, or not. Either it is justified by faith only (apart from any works) or justified with works in the mental equation.

Now this has caused confusion because although in terms of protestant justification our works are not a microscopic part of the equation; yet all who are justified of necessity produce good works as a fruit of the 'alien justification' (i.e. external righteousness of Christ imputed to them). Although 'sanctification' includes the discussion of works and 'cooperation with grace', justification excludes them. Our works having nothing to do with justification at all, but they play a big role in our sanctification. However under the Catholic scheme works are an 'important' part in justification. Actually justification and sanctification are really not much different under the Catholic scheme (i.e. we need continued cooperation with grace in order to be finally justified). Thus Protestants view the Catholic doctrine as works based righteousness hypocritically sprinkled with grace. These two sides should really be clear and do not need any evaluation of Latin or Greek, or German or the invention of different kinds of grace, different kinds of law, etc. Such philosophies only cloud the light of day upon which the Protestant religion was produced. We can’t have it both ways, either our works are considered in 'some sense' in our justification before God, or they are 'not'. One is a classical Protestant view and the other is a Catholic (or Orthodox or Syrian view).

As regards to 'if this is really foundational to Protestantism' the answer is more than anyone probably realizes today.

Just to make it clear that I am accurately representing the reformers on this point I leave a quote from Luther that spells out clearly the difference between those who mix sanctification (i.e. holy love, or works of love) with justification, and those who do not.

The truth of the Gospel is this, that our righteousness comes by faith alone, without the works of the Law. The falsification or corruption of the Gospel is this, that we are justified by faith but not without the works of the Law. The false apostles preached the Gospel, but they did so with this condition attached to it. The scholastics do the same thing in our day. They say that we must believe in Christ and that faith is the foundation of salvation, but they say that this faith does not justify unless it is “formed by love.” This is not the truth of the Gospel; it is falsehood and pretense. The true Gospel, however, is this: Works or love are not the ornament or perfection of faith; but faith itself is a gift of God, a work of God in our hearts, which justifies us because it takes hold of Christ as the Savior. Human reason has the Law as its object. It says to itself: “This I have done; this I have not done.” But faith in its proper function has no other object than Jesus Christ, the Son of God, who was put to death for the sins of the world. It does not look at its love and say: “What have I done? Where have I sinned? What have I deserved?” But it says: “What has Christ done? What has He deserved?” And here the truth of the Gospel gives you the answer: “He has redeemed you from sin, from the devil, and from eternal death.” Therefore faith acknowledges that in this one Person, Jesus Christ, it has the forgiveness of sins and eternal life. Whoever diverts his gaze from this object does not have true faith; he has a phantasy and a vain opinion. He looks away from the promise and at the Law, which terrifies him and drives him to despair.

Therefore what the scholastics have taught about justifying faith “formed by love” is an empty dream. For the faith that takes hold of Christ, the Son of God, and is adorned by Him is the faith that justifies, not a faith that includes love. For if faith is to be sure and firm, it must take hold of nothing but Christ alone; and in the agony and terror of conscience it has nothing else to lean on than this pearl of great value (Matt. 13:45–46). Therefore whoever takes hold of Christ by faith, no matter how terrified by the Law and oppressed by the burden of his sins he may be, has the right to boast that he is righteous (Luther’s works, vol. 26: Lectures on Galatians, 1535, Chapters 1-4.(Vol. 26, pp. 88–89).

Furthermore it should be clear that the reformers, when speaking about 'works of the law' meant moral goodness primarily and not the so called Mosaic legislation (i.e. ceremonies and civil laws). For example, speaking against Thomas who is arguable the emblem of modern Catholic dogma on the subject:

When Thomas and other scholastics speak about the abrogation of the Law, they say that after Christ the civil and ceremonial laws are fatal, and that therefore they have now been abrogated, but not the moral laws. These men do not know what they are saying. When you want to speak about the abrogation of the Law, discuss chiefly the Law in the proper sense of the word—the Law in the spiritual sense. Include the entire Law, without distinguishing between the civil, the ceremonial, and the moral. For when Paul says that through Christ we have been set free from the curse of the Law (Gal. 3:13), he is certainly speaking about the entire Law, and especially about the Moral Law. (Luther’s works, vol. 26: Lectures on Galatians, 1535, Chapters 1-4. (Vol. 26, pp. 446–447)).

    This answer does not represent the Catholic and orthodox doctrine of Justification accurately. Rather, it embraces the incorrect version perpetrated by anti-christ. In other words, it uses falsehoods, associates them or misrepresents those falsehoods as the teaching of the Catholic Church, then institutes a subjective doctrine apposing the false representation of the original to entice victims. I have no problem with an accurate representation of the New Christian doctrine of faith alone, but reject in this answer the idea is put out concerning the teaching or the Catholics. – Marc Apr 18 '17 at 17:28
  • I agree, you severely need to amend this, among other things: "do not believe in ... justification occurring when we are still God's enemies. They believe in justification as something requiring ‘our cooperation’ with grace (code word for works from a Protestant view) until we are finally justified in the final judgment...based on our ‘cooperation’ with grace." We believe that we are God's enemies until we are justified by the blood of Christ in bapt. Justification doesn't happen at Final Judgement, either. Scripture teaches co-operation with grace. Jas 2:22. Jn 15:1-10. – Sola Gratia May 17 '18 at 10:16

The Protestant belief known as "faith alone" ( commonly known as "Sola Fide").

It should be noted that not all Protestants believe in faith alone but all who believe in faith alone are Protestants since they are againts the teaching of Roman Catholic Soteriology of faith + works = salvation.

These Protestants are commonly known as Evangelicals/ Born Again Christians.

There are two facts to consider in order to understand the view of Evangelical/ Born Again Christians:

FACT # 1

saved by grace through faith alone NOT of works ( Ephesians 2:8-9)

justified by faith alone APART from works ( Romans 8:28)

FACT # 2

NOT saved & justified by faith alone ( James 2:14,24)

Obviously, there are two sorts of "faith alone" in the Holy Scriptures:

1) Faith alone that saves & justifies.

Notice that the focus is on salvation out from the WRATH of God:

Romans 5:9 + 3:28 saved from the wrath by the blood of Jesus

Ephesians 2:3 &14 + 2:8-9 children of wrath = brought near to God by the blood of Jesus

Also notice that the focus is on the WORKS OF THE LAW:

It is impossible to obey all the Law: For the mind that is set on the flesh is hostile to God, for it does not submit to God’s law; indeed, IT CANNOT (Romans 8:7).

For whoever keeps the whole law and yet stumbles in ONE point, he has become guilty OF ALL (James 2:10).

This Law includes the 10 commandments: who has made us sufficient to be ministers of a new covenant, NOT of the letter BUT of the Spirit. For the letter kills, but the Spirit gives life.Now if the ministry of DEATH, CARVED IN LETTERS ON STONE, came with such glory that the Israelites could not gaze at Moses’ face because of its glory, which was being brought to an end (2 Corinthians 3:6-7).

Question: What is the Law, then?

Answer: Paul himself asked and answered this question.

Why then the law? It was added because of transgressions, until the offspring should come to whom the promise had been made, and it was put in place through angels by an intermediary.Now an intermediary implies more than one, but God is one. Is the law then contrary to the promises of God? Certainly not! For if a law had been given that could give life, then righteousness would indeed be by the law. 22 But the Scripture imprisoned everything under sin, so that the promise by faith in Jesus Christ might be given to those who believe.Now BEFORE FAITH CAME, WE WERE HELD CAPTIVE UNDER THE LAW, imprisoned until the coming faith would be revealed So then, THE LAW WAS OUR GUARDIAN until Christ came, [ why?] IN ORDER THAT WE MIGHT BE JUSTIFIED BY FAITH. But now that faith has come, we are NO LONGER under a guardian (Galatians 3:19-25).

2) Faith alone that does not save and justify.

Notice that the focus is on SHOWING real faith and COMPLETING of it BY WORKS:

James 2:18 I will SHOW you my faith by my works.

James 2:22 You see that faith was working with his works, and as a result of the works, faith was COMPLETED.

How is faith completed ? Is faith alone lacking?

Faith is completed by works because if it lacks works then it is the same as " a body without a spirit", that is, dead or useless.

"Just as the body without the spirit is dead, so also faith without works is DEAD" ( James 2:26)

"But are you willing to recognize, you foolish fellow, that faith without works is USELESS?" ( James 2:20)

Also notice that the focus is on the WORKS FROM LOVE:

What good is it, my brothers, if someone "SAYS" he has faith but does not have works? Can that faith save him? ( James 2:14).

If a BROTHER OR SISTER ( Brethren) is poorly clothed and lacking in daily food, and one of you “SAYS” to them, “Go in peace, be warmed and filled,” without giving them the things needed for the body, what good is that? ( James 2:15).

John agrees with James for is expressing the same thing in his epistle: By this we know LOVE, that he laid down his life for us, and we ought to lay down our lives for the brothers. But if anyone has the world's goods and sees his brother in need, yet closes his heart against him, how does GOD'S LOVE abide in him? Little children, LET US "NOT" LOVE IN "WORD" OR "TALK" BUT IN DEED AND IN TRUTH ( 1 John 3:16-18).

Paul also agrees with James and John: In Christ Jesus neither circumcision nor uncircumcision means anything, but FAITH WORKING THROUGH CHARITY ( Galatians 5:6).

Yes. It is not from the Law but from faith working through charity (or love): But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control; AGAINST SUCH THINGS THERE IS NO LAW Galatians 5:22-23).


Romans 3:28 declared holy (to God) by faith apart from works [ of the Law] i.e. faith alone.

James 2:28 declared holy ( to brethren) by works [ from faith - specifically the faith that is "apart from works" in Romans 3:28].


To justify means to declare a person as holy.

Greek word: δικαιόω


The belief of Protestants ( Evangelicals / Born Again Christians) known as "faith alone" encompasses both the receiving of salvation (faith alone) and evidence of salvation( not by faith alone but also, of love and hope).
