Epistle

This term describes the literary form of 1 Corinthians itself — a pastoral letter written to a specific church to confront real problems, one of the most important such letters in the New Testament.

This epistle — Paul's letter to the Corinthians — contains verses 12–13 as arguably its most universally cited passage, offering both a humility check and a promise about God's faithfulness under pressure.

This epistle is identified as the most emotionally raw of Paul's letters, written not primarily to teach doctrine but to defend his integrity and bare his soul to a skeptical audience.

Epistle is used here to describe the very letter being read — Paul explicitly explains that writing in advance is his strategic choice to avoid having to discipline the Corinthians in person.

This term describes the literary form of 1 John itself — a pastoral letter written to correct dangerous theological errors spreading among early believers.

2 Timothy is itself an epistle — Paul is using this letter format because he cannot be physically present, making the written word his only available means of delivering this urgent pastoral challenge.

Epistle is used here to note that 3 John is the shortest letter in the New Testament canon, a private correspondence that nonetheless addresses timeless issues of leadership, hospitality, and integrity in the church.
