An aorist middle participle of apoginomai meaning 'having died' or 'having departed from.' Used in 1 Peter 2:24 for believers dying to sin through union with Christ's atoning death.
Peter's 'dying to sin' in 1 Peter 2:24 echoes Paul's Romans 6 theology: union with Christ's death means definitive departure from sin's dominion. The aorist marks this as a completed event -- the believer has 'departed' from sin. Now free to 'live to righteousness,' healed by His wounds (Isaiah 53:5).
