Antidikos denotes a person set against another, especially a party in a dispute or a hostile pursuer.

The attested use most often identifies the opposing party in a dispute that may proceed to a judge or a plea for justice; once it identifies the devil as a hostile pursuer seeking someone to swallow.

1. Opposing party in a legal dispute · dominant

   In Matthew 5:25, the dative form occurs in the instruction to be reconciled while on the road, before the opposing party hands someone to the judge; the APB renders the clause with “your opponent.” In Luke 12:58, the genitive form is the person accompanying someone toward a ruler, and in Luke 18:3 it is the party against whom the widow seeks justice.

2. Hostile pursuer · rare

   In 1 Peter 5:8, the nominative singular masculine form identifies the devil in the warning to keep watch; the APB renders the clause “Your opponent the devil,” who walks seeking someone to swallow.

   1 Peter 5:8

In the Anselm Project Bible: The APB uses “opponent” in each cited verse, placing the term in legal-conflict clauses in Matthew 5:25, Luke 12:58, and Luke 18:3, and in the warning about the devil in 1 Peter 5:8. This rendering confirms the verse-level presentation rather than isolating every contribution of the Greek form.
