The Greek word allotriepískopos (ἀλλοτριεπίσκοπος) is a compound of allotrios (belonging to another) and episkopos (overseer). It refers to one who meddlesome concerns himself with the affairs of others — a busybody who overseers what is not his business.
This rare compound word appears once in 1 Peter 4:15 alongside murderer, thief, and evildoer — remarkable company that highlights how seriously Peter views unauthorized interference in others' lives. The Christian is called to suffer, if suffer they must, as a Christian rather than as a meddler. There is a counterfeit 'oversight' that masquerades as concern but is actually presumption — bypassing the spiritual authority structures God has established. True Christian accountability is invited, not forced; it is humble, not intrusive. The believer is to mind their own calling before God.
