enemy, foe, opponent

Mnemonic

A ninja sneaks into a church to steal sacred relics, but the priest spots him and brands him an enemy of God. The ninja vaults over pews, but the church doors slam shut—trapping the enemy inside with an enraged congregation closing in on all sides.
Additional thoughts
Picture a black-clad ninja surrounded by stained-glass light, cornered among wooden pews—an enemy caught on holy ground. The contrast of stealth vs. sacred space makes it stick.
Quick recall
A ninja caught inside a church is declared an enemy of God.
