Genre

Epistle / Theological

Position

23rd NT book - Johannine Letters

Authorship

The Apostle John, written in old age from Ephesus. The author's insistence on what we have heard, seen, and touched (1:1) reflects eyewitness authority addressing Docetic/Gnostic teaching that denied Jesus came in the flesh.

Historical Context

The Johannine community faced a schism - members had left (2:19) who denied Jesus's full humanity. The remaining believers needed reassurance of their standing and clear criteria to distinguish true and false teaching.

Purpose

To provide assurance of eternal life to genuine believers, to counter Docetic teaching by insisting on the full humanity and blood of Jesus, and to call believers to love one another.

Key Message

God is love - and knowing God is inseparable from loving others; test every spirit, walk in the light, and love one another as the mark of being born of God.
