How Should We Read New Testament Epistles?

Question 1178.

New Testament epistles make up a large part of the New Testament, thirteen from Paul alone, plus further letters from James, Peter, John, Jude and the writer to the Hebrews, and they contain some of the richest doctrinal teaching in all of Scripture, alongside deeply practical instruction for ordinary Christian living. Reading them well requires a slightly different set of habits than reading narrative or poetry, because these are, first and foremost, real letters, written by real people to real churches facing real, specific, first-century circumstances we have to work to reconstruct rather than simply assume.

I want to set out carefully how I personally approach reading New Testament epistles week by week, and why remembering their original, first-century letter form genuinely changes how carefully, and how well, we end up applying them to our own lives today.

New Testament Epistles: Remember You Are Reading Someone Else’s Mail

The single most important thing to remember when reading these letters is that you are reading someone else’s mail. Paul wrote to the Corinthians because of specific, documented problems in that particular congregation, factions, sexual immorality, disorder at the Lord’s Supper, confusion about spiritual gifts. He was not writing a systematic theology textbook organised by topic for a general audience; he was answering questions, correcting errors, and addressing a pastoral situation he knew in detail and his first readers understood immediately, in ways we often have to work to reconstruct from clues within the letter itself.

This does not, in any sense at all, make the letters any less fully authoritative or less directly, urgently relevant to us as believers today. It does mean careful reading requires asking what situation prompted a given instruction before assuming how, or whether, it transfers directly to a different situation today.

Distinguish the Occasion From the Principle

Good interpretation of New Testament epistles distinguishes between the specific occasion prompting a passage and the abiding theological principle the passage teaches, without assuming every specific application automatically transfers unchanged. Paul’s instruction about head coverings in 1 Corinthians 11 sits within a specific first-century cultural context regarding public honour and shame that scholars continue to research carefully; the underlying principle, that public worship should reflect God-given order and mutual honour between men and women rather than confusion or dishonour, clearly transfers. Working out precisely which specific applications transfer unchanged and which require careful contextual translation into our own setting is real interpretive work, not an excuse for dismissing whatever a passage happens to say that we find inconvenient.

A Worked Example: 1 Corinthians and Head Coverings

It helps to work through an actual case rather than staying purely theoretical. First Corinthians is an especially instructive letter because Paul frequently quotes the Corinthians’ own slogans back at them before correcting them, “all things are lawful for me” (1 Corinthians 6:12) being a phrase almost certainly borrowed from Corinthian argument rather than Paul’s own settled position, which he immediately qualifies. Missing this rhetorical pattern leads readers, sometimes quite confidently, to attribute positions to Paul that he is in fact quoting only in order to correct and firmly reject a few sentences later. Careful readers learn to watch for these seams, places where Paul appears to be citing, then answering, an argument circulating in the congregation itself.

This kind of close reading is not a technique reserved for scholars with access to specialist commentaries. Reading a letter slowly, in full, more than once, and asking simple questions, who is Paul addressing here, what seems to have prompted this instruction, does most of this work for an attentive ordinary reader without any specialist training required at all.

Watch for Household Codes and Their Structure

Several epistles include what scholars call household codes, structured instructions addressed in turn to wives and husbands, children and parents, servants and masters (Ephesians 5:22 through 6:9, Colossians 3:18 through 4:1). Reading these well means noticing the structure itself: each pairing receives mutual, reciprocal instruction, not instruction flowing only one direction, and each instruction is grounded explicitly in the gospel, wives and husbands mirroring Christ and the church, servants serving as though serving Christ Himself. Isolating a single half of one of these paired instructions from its reciprocal partner and its gospel grounding produces a badly distorted reading of what the passage is actually doing.

Follow the Argument, Not Just the Verse

Paul in particular writes in sustained, connected argument, building a case across paragraphs and sometimes entire chapters rather than delivering a string of independent aphorisms. Romans 8:28, “all things work together for good,” is frequently quoted in isolation, yet Paul’s own argument specifies precisely what good he means two verses later, being “conformed to the image of his Son” (Romans 8:29), and the whole passage sits within a sustained argument about suffering, the Spirit’s groaning intercession, and future glory that began several chapters earlier. Reading epistles well means tracing the connective words, therefore, but, for, so that, which mark the actual joints of the argument, rather than mining individual verses for standalone quotations.

Notice the Balance of Doctrine and Practice

Many of Paul’s letters follow a recognisable pattern, extended doctrinal exposition in the earlier chapters followed by sustained practical exhortation in the later chapters, built explicitly on that doctrinal foundation. Romans spends eleven chapters on doctrine before Paul writes “I appeal to you therefore” in Romans 12:1, and that “therefore” is doing real theological work, grounding every subsequent practical instruction in the preceding eleven chapters of doctrine rather than presenting ethics as a free-floating set of rules. Reading the practical sections of an epistle without their doctrinal foundation risks turning apostolic exhortation into bare moralism, disconnected from the gospel grace that actually motivates and empowers it throughout the New Testament.

Reconstructing the Original Situation

Careful readers of these letters often benefit from what scholars call mirror-reading, inferring the situation a letter addresses from the content of the letter itself, since we rarely have the other side of the correspondence. This must be done cautiously and with real humility; over-confident, speculative mirror-reading has produced some genuinely strange and occasionally quite fanciful interpretations over the years, reconstructing elaborate imagined scenarios the actual text never clearly supports. But used carefully, alongside what we know from Acts and the wider historical background of the first-century Mediterranean world, it helps enormously in understanding why a particular instruction was given, which in turn helps determine how directly it applies to circumstances that may or may not resemble the original occasion.

How This Fits the Wider Task of Interpretation

This approach to these letters is simply the literal-grammatical-historical method applied to epistolary writing specifically, the same basic method I use when reading Old Testament narrative or biblical prophecy, adjusted to fit the specific literary conventions of first-century letter writing. Every genre in Scripture rewards this same basic discipline: understand the kind of writing you are reading, on its own terms, before applying it.

Why Genre-Sensitivity Protects Against Two Opposite Errors

Reading epistles carefully guards against two opposite mistakes I encounter regularly in pastoral ministry. The first treats every instruction as timelessly, woodenly binding regardless of cultural particularity, refusing to distinguish a first-century cultural expression of a principle from the principle itself. The second swings the other way, treating almost every instruction as simply cultural and therefore optional, quietly emptying the epistles of any real claim on how we live today. Careful attention to occasion, argument, and the letter’s own theological grounding is what actually protects against both errors at once, rather than defaulting to one extreme or the other out of theological convenience.

I find, in practice, that congregations taught patiently to read this way become noticeably more confident handling difficult passages themselves, rather than depending entirely on a pastor to tell them what a text means. That confidence is worth cultivating deliberately, week after week, rather than assuming it will simply develop on its own. This discipline rewards patience more than cleverness; the payoff comes gradually, letter by letter, as familiarity with Paul’s habits of argument and the wider first-century context slowly deepens over years of steady reading rather than arriving all at once from a single study session.

So, now what?

Next time you open one of Paul’s letters, or James, or Peter, or John, try reading the whole letter in one sitting before returning to study individual verses, the way you would read any letter addressed to you personally. Notice where the argument turns, what problem prompted the instruction, and how the practical exhortations grow out of the doctrinal foundation laid earlier. Read patiently and carefully this way, New Testament epistles stop feeling like a scattered collection of loosely connected quotable verses and start feeling like exactly what they genuinely are: real pastoral letters, written with real personal care and real theological depth, to real churches not so very different in their struggles from your own congregation today.
