A man given to arguing becomes for himself a double-edged sword; he destroys his soul, without knowing it, and renders it alien to eternal life.

An argumentative man is like someone who deliberately gives himself up to his king’s enemies. Argument is a fishing line baited with veracity (defence of truth, self-justification, self-defence) by which we are seduced into swallowing the hook of sin.
— St. Simeon the New Theologian
