One given to abusive, slanderous, mocking speech. Greek loidoros. Listed by Paul as a category of brother whose fellowship the church must refuse: But now I have written unto you not to keep company, if any man that is called a brother be a fornicator, or covetous, or an idolater, or a railer, or a drunkard, or an extortioner; with such an one no not to eat (1 Cor 5:11). The category appears alongside reviler (which translates the same Greek word in some passages) in 1 Cor 6:10 as one of the categories excluded from inheriting the kingdom. Railing is not just sharp disagreement, prophetic rebuke, or pointed correction (all of which are biblical in their place); it is the settled habit of abusive, contemptuous, character-attacking speech. Peter notes that Christ Himself, when he was reviled, reviled not again (1 Pet 2:23) — the model for Christian response to railing. The Christian does not become the railer he confronts.
