What is the rule of faith?
Answered from the commentary of J. N. Darby, William Kelly, The Christian's Friend and 2 others
The rule of faith is the written word of God, the Scriptures, which alone have divine authority and are the fixed, sure and unerring standard by which every teaching is to be tested. Tradition and the church are not another rule, and ministers, parents and teachers may communicate the truth but are means of teaching, not a rule of faith. The Holy Spirit enables the believer to understand and use the Scriptures, applying them to the heart and conscience; He is the power for receiving and obeying the rule, not a second rule alongside it. Thus the Scriptures are to be held in faith and love in Christ, and their truth is to govern life and conduct.

The passages the answer is drawn from, the most direct first, with the words that bear on the question marked.
As the truth of God is in the word, or rather as it is the truth, of course the Holy Ghost can use the scriptures to convince of sin, of righteousness, and of judgment, and, blessed be God, thousands of souls have thus found life and peace; but that is not our subject, but what is the sure rule of faith when we do profess Christ to be our Lord. There is a ministry of the word and parental responsibility in the church of God. God alone can give efficacy to either by His grace, but men are not left to discover a religion. Christianity is the activity of God to communicate the knowledge of the truth, and grace which saves and gives eternal life, the knowledge of Christ. This is carried out by the ministry of the word and parental care, but that is not a rule of faith, but an appointed means of grace. This the Roman Catholic professes to believe as well as Protestants. None pretends a parent, or even a priest, is infallible. The question is — supposing men who profess Christianity teach differently, what is the rule by which a sincere person may know with certainty what the truth in that matter is? We say the rule of faith is the written word of God. You say the Bible and tradition taken together, or the word of God, written and unwritten, and that, besides the rule itself, Christ has provided in His holy church a living, speaking, judge to watch over it, and explain it in all matters of controversy. That is, that, in fact, the word, written or unwritten, is no rule for him at all; he must submit to what is told him by the living judge. If the judge pronounces and decides the matter, that is the rule for him who has to submit to it; he cannot refer from the judge to the law.
N*. Where then is your rule of "what is held by all, everywhere, and always"? Moreover, many do hold this still, and it was favoured by the Bourbons, and was, even often, by the emperor, who can do so because he names the different prelates. But see what you have brought us to. Your rule of faith in 1682, for France at least, was different from your rule of faith in 1862. Is this its certainty and clearness? Now when I turn to scripture I find that which I surely need the grace of God to understand; but what is of admitted certain authority for all (except for infidels, with whom we have nothing to do here), and the same at all times? The word of God, the direct revelation given by God by prophets and apostles and inspired men, and that with a holiness, plainness, graciousness of love, and divine love and authority which act on the mind of the poorest, and which the poorest can appreciate. You hinder his having any rule, or else he must have councils and fathers, and read through folios in Latin and Greek; and, when a man is able to do that, he finds, as we have seen, contradiction and heresy, and no sure rule anywhere. If he cannot do this, he must resign himself blindfold into a man's, perhaps a wicked man's, hand. With scripture he listens to Paul and Peter and the rest; he finds and knows in his own conscience that he has to do with the word of God, which discerns the thoughts and intents of the heart. You have no certain rule of faith, nor any living word of God in what you call such which can judge your thoughts and heart.
The help and teaching of the Holy Ghost, and the written word, are not two rules of faith. The scriptures are the one sure rule, and the Holy Ghost He who works in the believer to enable him to use that rule, and not merely as a rule but as the food and edification of his soul. And in this the contents of scripture are adapted to the progress the soul makes in divine things and its state in every respect. It is applied by the Holy Ghost to the conscience and heart of the humble Christian who owns his need of the grace of God, and looks for it according to his need. The person who denies this is an heretical denier of the grace and goodness of God. Mark this, because Dr. Milner, who I suppose from his book is an unbeliever as to this, carefully leaves it all out. If men go on presumptuously, without depending on the grace of God, they will err as to scripture, and as to everything else, whether they call themselves Catholic or Protestant. Do you deny, M., the need a Christian has of the grace of God, and the goodness and faithfulness of God in giving it, and the gracious operations of the Spirit of God in the Christian's heart, as it is said, "The meek shall he guide in judgment, and the meek shall he teach his way"; or, as the Lord said, speaking of His people, "They shall be all taught of God"?
Our apostle, like Paul, had his dissolution before his eyes as well as the increasing evil through false teachers in depravity, and scepticism. Both are distinct in pointing to scripture as the great safeguard. As they alike set aside tradition, so they exclude any thought of apostolic succession. Grace might raise up faithful men to teach the truth they had learnt, or even to instruct others competent to communicate it. But scripture alone is the rule of faith, the sole unerring standard given of God to all His children whereby to test what they hear; and it is all the more blessed and necessary, as wicked men and impostors advance for the worse, leading and led astray. Scripture alone has divine authority. Therein God speaks directly to every soul; as indeed the apostle John also expresses it in his First Epistle, We [the inspired, apostles and prophets] are of God: he that knoweth God heareth us; he that is not of God heareth not us. From this we know the Spirit of truth and the spirit of error" (1 John 4:6). No one honoured scripture as Christ did from first to last, on the cross, and when risen from the dead. He even set the written word as a definitive witness beyond His own spoken words (John 5:47).
This is a grand difficulty for Dr. Milner; because after all, when Christianity has really to be discovered (as in the case of a heathen), it is discovered by the power of the word through grace, without the church at all. That is, in a word, that, in the only real case where the true religion is discovered, it is discovered without the authority of the church. Now for communicating the knowledge of Christ's religion where it is professed, there are similar means, as I have said, ministers, parents, and the like. And do you mean to say that special grace is for heathens to receive the word, but that there is none needed, and none given for professing Christians? It is needed for every man. But, remark further, this way of discovering Christ's religion is not a rule of faith. A minister, a priest, as you call him, is not a rule of faith; a friend or a mother is surely not a rule of faith. Yet they are the means in an ordinary way of the discovering, or more properly of the reception of, Christ's religion. Now the confusion of these things is the source of all the fallacy; because the means of discovering need not be infallible — need not be, in the sense here stated, secure nor universal; in point of fact, unless when scripture is the means, it never is; on the contrary, it is adapted to the state and capacity of the person evangelized or taught.
A rule of faith must be secure, but as it is not the means of communicating Christ's religion (though it may be such a means), it is not as a rule required to be adapted to such universal communication. It subsists in the form in which it was originally given to be referred to. Now these two things we have without the authority of the church at all: apostles, ministers, parents, and others, communicating Christ's religion according to the language or capacity of hearers and learners; and we have the scriptures the fixed and unchanged rule to which all teaching is to be referred. And note this well: if the truth contained in scripture be not received, if a man remain an infidel, or become a confirmed heretic, the authority of the church is of no use. For such do not acknowledge it. She must in result leave them where they are, unless she burn them (as Rome indeed has done by hundreds and thousands) or banish and imprison them. But that is only copying the heathen who did the same thing.
The greater part of the New Testament is comprised in the first source of authority, "knowing of whom thou hast learnt them," namely, all that which the apostles have written; because, in learning the truth therein, I can say I know from whom I have learnt it — I have learnt it from Paul, or from John, or from Peter, etc. But, besides this, being received as scriptures, they have the authority of divine writings, to which, as a form of communication, God has given the preference above the spoken word. They are the permanent rule by which every spoken word is to be judged.
In a word the scriptures are inspired. They teach, they judge the heart, they correct, they discipline according to righteousness, in order that the man of God may be perfect, that is, thoroughly instructed in the will of God, his mind formed after that will and completely furnished for every good work. The power for performing these comes from the actings of the Spirit. Safeguard from error, wisdom unto salvation, flow from the scriptures; they are capable of supplying them. We are to abide in that which we have learnt from the apostles, and to be governed by the writings of God.
Ephesus, the third general council, decreed that nothing should be added to the creed. The great doctrinal point on which the Greek church split from Rome was the addition of filioque, "and from the Son," made to the creed. It appears to have come from Spain; and the eminent Pope Leo, a very able man, when consulted about it from France, said the doctrine was right, but that it ought not to be added to the creed. Yet this remains one great point of difference between East and West to this day. So little is there any certainty of faith to be found in this way, so false is it, that if we have scripture we can have what was held always, everywhere, and by all, unless they departed from the faith once delivered to the saints. The rule is true, not because that universality gives authority, for the church only receives truth, but if it was always held it was held by the inspired authors at the first, who received the revelation from God, and hence, and hence only, has authority. And the simple way of knowing what they held is by seeing what they teach. Holding gives no authority; revelation does. Hence we have what is certain in scripture, and nowhere else.
In approaching our consideration of the New Testament, it is well to premise that there are two common errors in the present day, and found almost everywhere in Christendom: 1, That the use of the Bible is only to teach persons the way of salvation; and 2, That the Book of Revelation is too difficult for any one to understand. As to the first point, it is plainly said that the scriptures are not only able to make "wise unto salvation through faith which is in Christ Jesus," but that every scripture is God-breathed, or "given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness; that the man of God may be perfect, throughly furnished unto all good works." (2 Tim. 3:15-17.) Thus we see that the scriptures are the complete and all-sufficient guide of man after he has been born of God and saved from coming wrath. There is another point of all importance here. When the inspired apostle says that "evil men and seducers shall wax worse and worse, deceiving and being deceived," he turns to scripture as the only resource in an evil day; and would have Timothy know of whom he had learned the things he had been assured of. If many were asked in the present day from whom they had learned this doctrine and that, they would find it difficult to reply; some would say, "Our church teaches it." Now, true Spirit-taught and Spirit-led souls would say they learnt it from the scriptures, and therefore they can assert its divine authority. This is the exercise of faith, and nothing short of it can be pleasing to God. And as to the expression, "Our church teaches," it is not only unauthorised by the scriptures, but exactly opposite to scripture, for there we learn that, instead of the church teaching, the church is taught, and built up by various gifts from an ascended Saviour. (Eph. 4:11-12.) If any take refuge in another snare, that such and such doctrines must be true because the clergy have accepted them, we do well to remember that "the faith was once delivered to the saints," and is therefore the common possession of all true believers. The scriptures, not clever men, or preachers, or traditions, are our resource in these evil days; but we are enjoined to have that abiding in us which we have heard from the beginning; that is, the beginning of Christianity. (1 John 2:24.)
It is in vain then, as we agree, to speak of zeal to keep the unity of the Spirit, unless we hold "one faith." How far Romanism is true to "the faith" has been shown in §4. Nor is their flagrant departure surprising; for they have overlaid the holy deposit by their superstitions and profanely fabulous supplements. The true rule of faith is thus hidden from them. God has not left the faithful without the certainty of His mind. As the Lord laid down so solemnly (in the Rich man and Lazarus), "They have Moses and the prophets: let them hear them;" so we can say, We have Christ and the apostles. There is the Christian magisterium. It is not gifts or ministry, however real and precious in their place, but the teaching of the Lord Jesus and of those He inspired to give by the Holy Spirit what they could not bear before redemption.
Nor do I see what the communication of what he had learned to faithful men (2 Tim. 2:2), so as to form teachers, has to do with tradition. Nobody, unless they deny ministry, could gainsay this; and as far as a man could be trusted as receiving it from St. Paul, it would of course have weight; but that is just the question. It was not authority, but a means of communicating truth. The confounding these two things is generally the unperceived sophism of Milner's End of Controversy: "A rule of faith, he says, or means of communicating Christ's religion. It must be plain, etc." But these things are not the same. A mother does it to her babe, but she is not a rule of faith; she does it perhaps perfectly well, but this alters nothing. Now here the apostle is directing the means of communicating. truth to others (of course as surely as he can), but not setting up either authority or a rule of faith. When I had a dozen young men reading with me at Lausanne, I was doing this according to my ability. Was I dreaming of setting up authority or a rule of faith in them? Certainly not. The written word is clearly such the moment we own it inspired.
