Archaic KJV Word
Trespass
Modern equivalent: sins
What Was Lost
The spatial, boundary-crossing metaphor. To trespass against someone was to invade their God-given territory -- their dignity, their rights, their peace. The word made sin tangible and spatial: you crossed a line you knew was there.
Closest Survivor in Modern English
trespass (still used in the Lord's Prayer by tradition, but hearers picture property lines)
Peak Usage (1611)
KJV Matthew 6:14-15 -- 'If ye forgive men their trespasses'
Died ~1950
Narrowed from 'spiritual violation/transgression against God and neighbor' to primarily 'unauthorized entry onto property,' making the Lord's Prayer sound like a real estate dispute.
What Replaced It
“sin”
Too broad and generic; trespass specifically meant crossing a known boundary -- deliberate encroachment into forbidden territory
“offense”
Focuses on the victim's feelings; trespass emphasized the violator's deliberate boundary-crossing
“wrongdoing”
Vague and morally diluted; trespass carried spatial imagery of invasion
