I. Introduction and Text
The passage under examination is 2 Peter 1:19–21, which reads:
“We have also a more sure word of prophecy; whereunto ye do well that ye take heed, as unto a light that shineth in a dark place, until the day dawn, and the day star arise in your hearts: knowing this first, that no prophecy of the scripture is of any private interpretation. For the prophecy came not in old time by the will of man: but holy men of God spake as they were moved by the Holy Ghost.” (2 Peter 1:19–21, KJV)
This passage has generated significant discussion across centuries of biblical scholarship, and the confusion frequently begins with the English translation of a single phrase: “private interpretation.” The Greek behind this phrase is idias epiluseōs — literally, “of one’s own loosing” or “of one’s own release.” The noun epilusis carries the sense of unloosing, releasing, or explaining something bound up. The adjective idios means one’s own, private, personal, originating from oneself. Together they form a phrase that can bear two closely related but distinguishable meanings: that scripture did not originate from individual human initiative, and that scripture is not properly interpreted by isolated individual opinion.
Both meanings are legitimate and, as this paper will argue, both are in view. The local context makes the question of origin primary, while the broader canonical witness expands the application to include the question of interpretation. To separate these meanings entirely is to impoverish both; to conflate them without distinction is to obscure the precise weight Peter places on the prophetic character of Scripture itself.
II. The Local Context: 2 Peter 1 and the Apostolic Eyewitness
A. The Setting of the Warning
To understand what Peter means by “private interpretation,” one must read the passage within the argument Peter is constructing from verse 12 onward. He is near the end of his life (verse 14 — “shortly I must put off this my tabernacle”), and his concern is that his readers will retain the truth of the gospel after his departure. He is not writing to novices uncertain about whether the gospel is true. He is writing to confirm them in what they already know.
In verses 16–18, Peter grounds the apostolic witness in direct eyewitness testimony of the Transfiguration: “For we have not followed cunningly devised fables, when we made known unto you the power and coming of our Lord Jesus Christ, but were eyewitnesses of his majesty.” The contrast Peter is drawing is between muthoi — myths, cunningly devised fables — and the bebaioteron prophetikon logon — the “more sure word of prophecy” of verse 19. Peter’s argument moves from the visible, auditory, experiential apostolic witness on the holy mount to the even more certain foundation of the prophetic word. The eyewitness is reliable; the prophetic scripture is more reliable still.
This is the argumentative context in which verse 20 appears. When Peter says that no prophecy of scripture is of private interpretation, he is not introducing a new and unrelated subject. He is explaining why the prophetic word is so certain and so authoritative — because it did not originate in the private initiative of individual human beings. The connection word is touto prōton ginōskontes — “knowing this first” — which introduces verse 20 as a foundational premise that supports what has just been said about the certainty of scripture.
B. The Priority of the Origin Question
Verse 21 is the decisive explanatory statement: “For the prophecy came not in old time by the will of man: but holy men of God spake as they were moved by the Holy Ghost.” The Greek ou gar thelēmati anthrōpou ēnechthē prophēteia pote — “for prophecy was not borne at any time by the will of man” — is a direct statement about the source and origin of prophetic scripture. The verb pherō (to bear, carry, bring) is used twice in this verse: once negatively (prophecy was not borne by human will) and once positively (holy men were borne by the Holy Spirit). The human authors were not the engines of prophetic scripture — they were the vessels. The Holy Spirit was the motive power.
This establishes that the primary meaning of idias epiluseōs in verse 20 is one of origin. Scripture is not the product of a prophet’s own private unloosing — his own release of ideas generated from within himself. When a prophet spoke, he was not spinning out his personal theological reflections, religious experiences, or moral intuitions. He was speaking what the Spirit of God moved him to speak.
The word translated “moved” is pheromenoi — the same root as the verb of bearing. Holy men were carried along by the Holy Spirit. This is a nautical metaphor Paul also employs: a ship carried by the wind. The sailors do not generate the wind; they set the sails. The prophets did not generate the content of their prophecy; they were the instruments through whom the Spirit communicated what He determined to communicate. This means scripture, at its point of origin, is not a human document that happens to contain divine truths. It is a divine document expressed through human instruments.
C. What This Excludes at the Local Level
At the local level, Peter’s statement excludes several categories of claimed spiritual authority:
It excludes prophecy by sheer personal religious experience. A man who reports his own visions and inner impressions as authoritative prophetic scripture is doing precisely what Peter denies — releasing (epilusis) what is his own (idios) and presenting it as binding revelation. This would become a pressing issue in the early assemblies where false prophets abounded (cf. 2 Peter 2:1, which immediately follows this passage, introducing pseudoprophētai — false prophets — as the direct application of the principle).
It excludes the reduction of scripture to merely human religious literature. If the prophets were only speaking their own thoughts about God — however elevated, however sincere — then scripture becomes a record of human religious development rather than a record of divine self-disclosure. Peter’s point cuts directly against this view: the prophecy was not borne by human will. Its origin is not in the human subject.
It establishes the continuity between old prophetic scripture and apostolic witness. Peter’s argument is that the same Spirit who moved the prophets confirmed the apostolic testimony — which is why the word of prophecy is “more sure,” not less sure, than even the eyewitness experience on the holy mountain. The Transfiguration was spectacular but singular; the prophetic word is the settled, written testimony of the Spirit across centuries of history, converging on Jesus Christ.
III. The Interpretive Dimension: What “Private Interpretation” Means in Practice
While the origin question is primary in Peter’s immediate argument, the term epilusis cannot be cleanly restricted to origin alone. Epiluō in its cognate verb form is used in Mark 4:34 for Jesus “expounding” the parables to his disciples, and in Acts 19:39 for a matter being “determined” in a lawful assembly. The semantic range of the word includes the act of explaining and unloosing what is bound up — which is, precisely, what an interpreter does with a text. To say that no scripture is of private unloosing is therefore, at minimum, to raise the question: if the text did not originate from private human initiative, can it legitimately be interpreted by private human initiative alone?
The answer the whole of Scripture supplies is: no. And this is where the local context opens into the canonical context.
A. The Interpretive Problem Peter Is Addressing
The false prophets and false teachers of 2 Peter 2 and 3 are not simply people who invented new doctrines from scratch. They are people who handle scripture in a particular way — a way that serves their own interests and presuppositions. In 2 Peter 3:16, Peter explicitly addresses this: “As also in all his epistles, speaking in them of these things; in which are some things hard to be understood, which they that are unlearned and unstable wrest, as they do also the other scriptures, unto their own destruction.”
The word “wrest” is streblousin — to twist, distort, torture. The unstable and unlearned are twisting Paul’s letters and the other scriptures. This is private interpretation in its most visible form: the reader brings a prior agenda, a personal interest, or an unconverted framework to the text and torques the text until it yields what the reader wanted it to say. The text is made to serve the interpreter rather than the interpreter being made to serve the text.
This is the interpretive counterpart to Peter’s statement about origin. If scripture originated not by private human will but by the Holy Spirit, then the proper interpretation of scripture must also operate in submission to the Spirit’s intent — not in the service of the interpreter’s private interest, prior conclusion, or unconverted desire.
IV. What Separates Legitimate Reading from Private Interpretation: Six Distinguishing Marks
Having established both the origin and interpretation dimensions of Peter’s warning, we can now draw from the broader biblical witness to identify what separates legitimate reading of scripture from the private interpretation Peter condemns.
A. Submission to the Whole of Scripture
The most fundamental rule of legitimate biblical interpretation, repeated throughout the biblical witness itself, is that no passage is rightly understood in isolation from the whole. Paul states in 2 Timothy 3:16–17 that “all scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness.” The word all (pasa) is comprehensive. No part of scripture can be legitimately interpreted against the rest of scripture, because the same Spirit who moved one prophet also moved all the others. If an interpretation of one passage contradicts the clear teaching of the broader witness, the interpretation is wrong — not the scripture.
This is the principle of analogia scriptura — scripture interpreting scripture — which is not a later ecclesiastical invention but is rooted in the prophets themselves. Isaiah 28:10 — “precept upon precept, line upon line” — describes a method of building understanding through the accumulation of the whole. Jesus Christ Himself, on the road to Emmaus, interpreted the scriptures from Moses through all the prophets (Luke 24:27), demonstrating that legitimate interpretation reads along the grain of the entire canonical witness, not against it.
Private interpretation characteristically isolates. It selects a verse, a phrase, or even a fragment of a phrase, severs it from its literary context, its book context, its canonical context, and its historical-prophetic context, and then constructs a meaning that serves a predetermined conclusion. The interpretive isolation is itself the sign of the private agenda.
B. Submission to the Original Intent and Meaning of the Text
Legitimate interpretation asks what the human author — moved by the Holy Spirit — intended to communicate in his original historical and literary setting. This is not a concession to a merely human reading; it is a recognition that the Spirit chose to communicate through particular human beings at particular times in particular genres using particular languages for particular purposes. To bypass this is not to read the Bible more spiritually but to substitute the reader’s imagination for the Spirit’s intent.
Private interpretation, by contrast, treats the text as a wax nose — something to be shaped by the reader’s current need, cultural assumptions, or theological preferences. The reader asks not “what does this text mean?” but “what can I make this text mean for my purpose?” The question itself reveals the nature of the enterprise.
C. Coherence with the Prophetic and Apostolic Testimony Concerning Jesus Christ
Peter’s argument in 2 Peter 1 centers on the prophetic word as a light shining in a dark place. The ultimate horizon of that light is the Day Star — a messianic title pointing to Jesus Christ (cf. Numbers 24:17; Revelation 22:16). The prophetic scriptures, rightly read, converge on Jesus Christ. This is Jesus Christ’s own hermeneutical claim: “Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of me” (John 5:39), and again: “Had ye believed Moses, ye would have believed me: for he wrote of me” (John 5:46).
Any reading of scripture — Old or New Testament — that does not cohere with this messianic center is suspect. This does not mean every passage must be forced into an artificial allegory pointing to Jesus Christ. It means that the whole canonical story has a direction, a telos, and an interpretive key, and that legitimate reading honors this direction rather than departing from it. The Pharisees had the scriptures and read them with great diligence. Their reading was private interpretation not merely because it served their institutional interests, but because it fundamentally missed the One to whom the scriptures testified (John 5:39–40).
D. Continuity with the Community of the Faithful
This requires careful statement, because the Reformation rightly rejected the claim that the institutional church alone possesses the authoritative interpretation of scripture. But the rejection of institutional monopoly is not the same thing as the affirmation of individual private reading as normative. Peter writes to a community — not to an isolated individual. The entire letter of 2 Peter is addressed to a corporate body of believers who hold a common faith (“them that have obtained like precious faith with us” — 2 Peter 1:1).
The corrective against private interpretation is not simply a stronger institution but a more faithful community. Paul in Ephesians 3:18 speaks of comprehending the dimensions of the love of Christ “with all saints” — the corporate dimension is built into the act of understanding. No individual reader, however gifted, however learned, has access to the full range of scriptural light available to the community of the faithful reading together across time and geography. Private interpretation is private precisely in its isolation from this communal accountability.
This does not render community infallible. False prophets operate in communities. Entire assemblies can err. The test of communal interpretation remains the text itself — but the individual reader who stands entirely outside any accountability to other faithful readers and claims superior insight to all others is exhibiting a hallmark of private interpretation, however orthodox his conclusions may occasionally be.
E. Consistency of Method
Legitimate interpretation applies its reading principles consistently across the whole of scripture. It does not allegorize passages that are inconvenient while literalizing passages that are congenial. It does not claim a text is culturally conditioned when it conflicts with contemporary preference while claiming the same type of text is timelessly binding when it supports a prior commitment. It does not require the plain sense of a passage when it serves an argument while dismissing the plain sense of an equally clear passage when it does not.
Private interpretation is habitually methodologically inconsistent because its real governing principle is not the text but the conclusion. The method changes to serve the conclusion rather than the conclusion emerging from the consistently applied method. This inconsistency is one of the most reliable diagnostic signs that a reading is operating in the private mode Peter warns against.
F. Accountability to the Text’s Own Corrective Function
Paul tells Timothy in 2 Timothy 3:16 that scripture is profitable for reproof (elegmon) and correction (epanorthōsin) — two of its four stated functions involve correction of what is wrong. Legitimate interpretation allows scripture to correct the interpreter. A reading that never produces any challenge to the reader’s prior beliefs, never demands repentance, never overturns a cherished assumption, never crosses the reader’s cultural or personal comfort — that reading has, by the law of probability alone, become domesticated to the reader’s own framework. The scripture has been made to mirror the reader rather than the reader being made to submit to the text.
Private interpretation, at its root, is self-protective. It handles the text in a way that insulates the interpreter from the text’s most demanding claims. This is precisely why Peter links it so closely to the false teachers of chapter 2, who “walk after their own lusts” (2 Peter 3:3). The desire that drives private interpretation is not primarily intellectual — it is moral. The interpreter does not want to be corrected, transformed, or submitted to a power beyond themselves. The form of interpretation becomes a defense against the power of what is being interpreted — which, in its own way, mirrors the warning of Paul in 2 Timothy 3:5 about those who have a form of godliness but deny its power.
V. The Canonical Witness: Other Biblical Voices on the Same Problem
A. The Bereans and the Right Use of Scripture
Acts 17:11 presents the Bereans as a model of legitimate engagement with scripture: “These were more noble than those in Thessalonica, in that they received the word with all readiness of mind, and searched the scriptures daily, whether those things were so.” Two things are notable. First, they received the word — they did not begin with suspicion or a determination to defend a prior position. Second, they searched the scriptures as the court of appeal. They did not search their own intuitions, their community traditions, or their interpretive preferences. The text itself, searched diligently, was the standard.
This is the opposite of private interpretation. The Bereans were willing to be shown something they had not previously believed if the scriptures confirmed it. Their minds were open to the text, not closed by prior commitment.
B. Nehemiah 8 and the Assembly Reading
The great public reading of the Law in Nehemiah 8 provides an instructive Old Testament portrait of legitimate communal interpretation. Ezra read from the book of the law and the Levites “caused the people to understand the law: and the people stood in their place. So they read in the book in the law of God distinctly, and gave the sense, and caused them to understand the reading” (Nehemiah 8:7–8). Three things characterize this reading: it is public and communal, it aims at the plain sense of the text (“gave the sense”), and it produces understanding and response in the hearers. The outcome is weeping (8:9) and joy (8:12) — both responses appropriate to an encounter with the actual content of what God has said.
Private interpretation produces neither this kind of weeping nor this kind of joy, because it has not actually encountered the text’s own content. It has encountered the reader’s own reflection in the text.
C. The Prophets Interpreting the Prophets
A remarkable feature of canonical scripture is the degree to which later prophets interpret earlier prophets. Daniel reads Jeremiah’s prophecy of seventy years (Daniel 9:2) and is driven to prayer and confession. Zechariah draws extensively from Ezekiel and Isaiah. The New Testament authors — Matthew, John, Paul, the author of Hebrews — read the Old Testament in ways that are internally consistent with one another while revealing depths of meaning in the original text that were latent but real. This is not private interpretation; it is Spirit-guided illumination of what the Spirit originally inscribed. The consistency across authors widely separated by time, culture, and circumstance is itself a testimony to the non-private origin of the whole.
When private interpreters produce readings that contradict this accumulated inter-canonical witness, they are not discovering new depth; they are departing from the channel of the Spirit’s own interpretive work already visible in the text itself.
VI. The False Prophets of 2 Peter 2: Private Interpretation in Action
Peter’s warning about private interpretation in chapter 1 is immediately followed by his description of false prophets and false teachers in chapter 2. This is not accidental. The false teachers are the concrete instantiation of what private interpretation produces. They are described in terms that map directly onto the interpretive failure Peter has just named:
They “privily shall bring in damnable heresies” (2:1) — the word pareisaxousin means to introduce secretly alongside what is legitimate. Their interpretive method is parasitic on the genuine.
They handle the truth as a commercial commodity — “through covetousness shall they with feigned words make merchandise of you” (2:3). Their interpretation serves financial and social interest. Their reading is shaped by what it will yield them, not by what the text actually says.
They “walk after the flesh in the lust of uncleanness, and despise government” (2:10) — their interpretive rebellion is rooted in moral rebellion. The refusal of the text’s authority over behavior and the refusal of the text’s plain meaning are two expressions of the same underlying posture of self-sovereignty.
They are “presumptuous” and “self-willed” (2:10) — tolmētai and authadeis — bold and self-pleasing. These are the temperament of the private interpreter: confident in their own reading, resistant to correction, self-authorizing.
The trajectory from private interpretation to heresy, moral failure, and presumption is direct. It is not that every private interpreter immediately arrives at all of these destinations. But the root — the insistence on subjecting the text to oneself rather than subjecting oneself to the text — contains all of these destinations within it.
VII. Synthesis: What the Warning Requires
Peter’s warning requires a posture toward scripture that honors both its divine origin and its divine purpose. Because scripture did not originate from private human initiative but from the Holy Spirit moving human authors, it cannot be legitimately handled by private human initiative unaccountable to the Spirit’s intent. The same Spirit who inspired the text is the Spirit who illuminates the text — and He does not illuminate it to mean something contrary to what He originally inspired it to mean.
The boundary between legitimate reading and private interpretation is therefore not primarily a methodological line — though method matters — nor primarily an institutional line — though accountability matters — but a spiritual and dispositional line. The legitimate reader approaches the text as a subject approaches the word of the sovereign: with readiness to hear what is said, willingness to be corrected by what is found, and submission to the authority of the One who spoke. The private interpreter approaches the text as an authority approaches a resource: extracting what is useful, dismissing what is inconvenient, and remaining sovereign over the whole.
Peter’s final exhortation is the proper summary: “Ye therefore, beloved, seeing ye know these things before, beware lest ye also, being led away with the error of the wicked, fall from your own stedfastness. But grow in grace, and in the knowledge of our Lord and Saviour Jesus Christ.” (2 Peter 3:17–18). The alternative to private interpretation is not passive reception but active, accountable, communal, Spirit-dependent growth in the knowledge of the One to whom the scriptures, properly read, always point.
VIII. Conclusion
Peter’s warning that no prophecy of scripture is of private interpretation (idias epiluseōs) operates simultaneously as a statement about origin and a principle of interpretive accountability. Scripture did not originate from private human initiative; therefore it cannot legitimately be interpreted by private human initiative alone. The Spirit who moved the prophets is the Spirit who illuminates the text — and He does so through the whole of the canonical witness, through the community of the faithful, through submission to the text’s own corrective function, and through coherence with the messianic center that gives the entire scripture its direction and its light.
What separates legitimate reading from private interpretation is ultimately a question of lordship over the text. The legitimate reader submits. The private interpreter does not. This is why Peter places his warning about private interpretation immediately before his extended account of false teachers — because the interpretive failure and the moral failure are not two separate problems. They are the same problem expressed in two different registers: the refusal of the self to be governed by a word that did not originate from itself.
This white paper is grounded in the received canonical text and draws from the internal testimony of Scripture in accord with a biblicist hermeneutic.
