A verb meaning 'to divide,' 'to separate,' or 'to draw a divisive boundary.' Used in Jude 1:19 for false teachers who 'cause divisions' while claiming spiritual superiority.
Jude exposes the supreme irony: those who lack the Spirit ironically mark off the 'spiritual' from the 'unspiritual.' True spiritual maturity is marked by unity-seeking and humility (Ephesians 4:3). 'The Spirit unites; flesh divides.' Jesus prayed 'that they may all be one' (John 17:21).
