What it holds: Scripture is the only infallible rule of faith; councils, fathers and traditions are judged by it, and nothing not provable from it may be required as necessary belief.

The supreme judge by which all controversies of religion are to be determined, and all decrees of councils, opinions of ancient writers, doctrines of men, and private spirits, are to be examined, and in whose sentence we are to rest, can be no other but the Holy Spirit speaking in the Scripture.Westminster Confession of Faith, 1.10 (1646)

Common ground
These are affirmed by more than one position, so a passage saying only this counts for none of them.
- Scripture is inspired by God and true
- Scripture is sufficient to refute heretics or to teach the faith (praise of Scripture alone decides nothing)
- Heretics misinterpret Scripture
- The 'rule of faith' or creed summarizes apostolic teaching
- Church teachers and councils are to be respected
Every deciding passage, earliest first
Irenaeus of Lyons, c. 180
When they are refuted from the Scriptures, they turn around and accuse the Scriptures themselves, as if the Scriptures were not rightly constituted, lacked authority, and contradicted themselves because they were expressed in various ways. They claim that truth cannot be discovered from the Scriptures by those who do not know the tradition. After all, the tradition was handed down not in writing, but by living voice. That is why Paul said, "We speak wisdom among the mature, yet a wisdom not of this world" (1 Corinthians 2:6-7). Each of these heretics then claims that this wisdom is exactly wha…

Irenaeus of Lyons, c. 180
When they are confronted with Scripture, they turn their attack against Scripture itself, claiming it is not rightly preserved, lacks authority, contradicts itself in its varied expressions, and cannot yield truth to those who lack the tradition. For that tradition was not handed down in writing but by living voice — which is why Paul declared, "We speak wisdom among the perfect, but not the wisdom of this world" (1 Corinthians 2:6). Each of these teachers claims that this wisdom is his own private discovery, a mere invention, so that truth might be whatever suits him: one moment it appears in…

They insisted that the men they were leaving behind as successors be thoroughly blameless and irreproachable in every respect, so that great benefit would come to those who would act in their place of teaching, while the greatest calamity would befall those who fell away. But because it would take far too long to list the successions of every church in a work of this scope, we will set forth the tradition that comes from the Apostles and the faith proclaimed to humanity, which has reached us through the succession of bishops from the most glorious two Apostles, Peter and Paul, who founded and …

Irenaeus of Lyons, c. 180
The apostolic plan stands revealed throughout the whole world; it is present for all who wish to see the truth to behold in every church. We can enumerate those whom the apostles instituted as bishops in the churches, along with their successions down to us — men who taught nothing of the kind, nor knew it, the very thing these people rave about. If the apostles had known hidden mysteries, which they taught separately and secretly to the perfect, they would have handed them over especially to those to whom they also entrusted the churches themselves. They wanted those they left as successors t…

It is necessary to obey the presbyters who are in the Church, those who possess succession from the Apostles, just as we have shown; for they, together with the succession of the episcopate, have received a certain charisma of truth according to the will of the Father (Leviticus 10:1-2). But those others who stand apart from the principal succession, and who gather in whatever place, must be regarded with suspicion, whether as heretics and men of bad judgment, or as those who divide, are puffed up, and please themselves, or again as hypocrites who act for the sake of gain and vain glory (Numbe…

If this is how things stand—that truth is awarded to us who walk the rule the Church received from the Apostles, the Apostles from Christ, and Christ from God—then the rationale behind our position is settled: heretics must not be admitted to a contest over Scripture. We have already proved, without using Scripture, that they have no connection to it. If they are heretics, they cannot be Christians; they possess nothing from Christ, yet they embrace the very name that marks their chosen faction. Not being Christians, they hold no right to Christian writings. So we are fully justified in demand…

So we lay down our rule: if the Lord Jesus Christ sent the Apostles to preach, then no other preachers are to be accepted except the ones Christ himself appointed. For no one knows the Father except the Son, and those to whom the Son chooses to reveal him. And the Son does not appear to have revealed the Father to anyone except the Apostles he sent to preach — precisely what he revealed to them. Now, what they preached — that is, what Christ revealed to them — I insist must be proved in no other way than through the very churches the Apostles themselves founded, preaching to them in person, as…

Still, if anyone dares to slot themselves into the apostolic age so they can claim the apostles handed them down—since they were 'under the apostles'—we can say: Let them produce the origins of their churches. Let them lay out the succession of their bishops, running unbroken from the start, so that their first bishop can show an apostle, or an apostolic man who stuck with the apostles, as his author and predecessor. That is how apostolic churches present their credentials: the church of Smyrna reports Polycarp was appointed by John; Rome produces Clement, ordained by Peter; likewise every oth…

If anyone dares to wedge themselves into the apostolic era just so they can claim the Apostles handed them down—on the grounds that they ‘lived under the Apostles’—we can answer bluntly: let them cough up the origins of their churches. Let them lay out the full line of their bishops, an unbroken succession from the very start, so that their first bishop can name an Apostle—or at least an apostolic man who stuck with the Apostles—as his author and predecessor. That is exactly how the apostolic churches present their credentials: the church of Smyrna records that John installed Polycarp; the Rom…

Go ahead: suppose everyone got it wrong. Suppose the Apostle was duped when he bore witness to certain people. Suppose the Holy Spirit never glanced back to guide anyone into truth, even though Christ sent Him for that very purpose and the Father dispatched Him to be the teacher of truth. Suppose the steward of God, the vicar of Christ, neglected his job and let the churches understand and believe something different in the meantime from what He Himself had preached through the Apostles. Is it really plausible that so many and such great churches all erred their way into a single faith? Among …

If this is how things stand, so that truth is adjudged to us who walk in that rule of faith which the church handed down from the apostles, the apostles from Christ, and Christ from God, then the reasoning of our position is established: we define that heretics must not be admitted to bring a challenge from the Scriptures, since we prove without the Scriptures that they have no claim to the Scriptures. For if they are heretics, they cannot be Christians, since they do not hold from Christ what they have followed by their own choice, and so they take on the name of heretics. Being therefore not…

So there must be no appeal to the Scriptures, and no contest established in them where victory is either nonexistent, or uncertain, or not certain enough. For even if a comparison of the Scriptures did not turn out in such a way as to make both sides stand equal, the order of things was requiring that this be proposed first, which alone is now to be disputed: to whom the faith itself belongs, whose the Scriptures are, from whom, and through whom, and when, and to whom was handed down the discipline by which people become Christians. For where it has appeared that the truth of the Christian dis…

If this is so, it is settled that every doctrine which agrees with those apostolic churches, the mothers and originals of the faith, is to be assigned to the truth. Such a doctrine undoubtedly holds what the churches received from the apostles, the apostles from Christ, and Christ from God. But every doctrine that savors against the truth of the churches and of the apostles of Christ and of God is to be judged beforehand as coming from falsehood.

You prescribe that the solemn observances of this faith were established by the Scriptures or by the tradition of the elders, and that nothing further in the way of observance may be added, because innovation is unlawful. Stand on that ground if you can. For look, I meet you as people who fast beyond Passover, apart from those days on which the bridegroom was taken away, who insert the half-fasts of station days, and who sometimes live on bread and water, as each of you sees fit. In the end you answer that these things are to be done by choice, not by command. So you have moved from your groun…

But as long as the form of the rule remains in its proper order, you may seek and discuss as much as you like and pour out all the desire of your curiosity, if anything seems to you to hang in ambiguity or be shadowed by obscurity. There is certainly some brother endowed with the gift of knowledge, some one among the trained, some curious person who has spent time with you—yet one who seeks with you. In the end he will know better that you should be ignorant, so that you may not know what you ought not to know, because you know what you ought to know. "Your faith," he says, "has saved you," no…

Athanasius of Alexandria, c. 373
Such, then, as we said before, is their madness and boldness. But our faith is right, and it springs from apostolic teaching and the tradition of the Fathers, and is confirmed by both the New and the Old Testament. The prophets say: Send out your Word and your truth (Psalm 42:3 LXX); and: Behold, the Virgin shall conceive and bear a Son, and they shall call his name Emmanuel, which is translated, God with us (Isaiah 7:14).

But let only the faith confessed at Nicaea by the Fathers hold sway among you. In that council, as we said before, all the Fathers were present—even those now fighting against it—and they signed. So the Apostle may say about us: “I praise you because you remember me in everything and hold firmly to the traditions just as I handed them on to you” (1 Corinthians 11:2). For this council at Nicaea is truly an inscription set up against every heresy. It also overthrows those who blaspheme against the Holy Spirit and call the Spirit a creature. For after the Fathers spoke about faith in the Son, the…

How this was made
Every whole work in the library on 21 October 2026 was searched for this question. Works added since then are not searched yet. The short excerpts on the topic pages (many from Tertullian, Justin, Irenaeus and Ignatius) join the search once their English has been checked against the Greek or Latin original: 94% of them (1,814 of 1,925) have passed that check, and the rest are still held out, so an early witness may occasionally be missing from these lanes. Two AI models from different labs judged each passage against all the positions at once, seeing them only as letters, without names or churches. A third model settled disagreements, and Claude reviewers then checked every deciding verdict against the passage and, for the earliest dates, against the Greek or Latin. A writer's silence is never counted.
The evidence is only as deep as the works searched: 1st century: 5 writers, 2nd century: 23 writers, 3rd century: 22 writers, 4th century: 18 writers, 5th century: 11 writers, 6th century: 5 writers, 8th century: 1 writer. The lanes are redrawn when the search is run again.
