1 John 4:1

The context

First John addresses a community troubled by teachers who have left and who deny something central about Christ. Chapter 4 opens with a direct command not to trust every spirit, then supplies a test: whether a spirit confesses Jesus Christ come in the flesh. The letter's tests are short and repeatable, and this is the first of them.

What it establishes

Claims to inspiration are to be evaluated. The letter assumes that prophetic speech exists, that it can be false, and that the community has both the right and the means to examine it. The criterion given is christological and concrete rather than emotional or institutional.

What it does not establish

It does not supply a general method. The test here is one question about Christ, not a procedure for assessing every religious experience or every teacher's whole doctrine. The command to test sits inside a letter whose other test is love.

Short note, first pass, October 2026. Corrections welcome.
