Romans 6:9

εἰδότες ὅτι, ‘appeal to an elementary Christian belief,’ Hort, 1 Peter 1:18; cf. Romans 6:3; 2 Corinthians 4:14; 2 Corinthians 5:6. A stronger form is οὐκ οἴδατε ὅτι, Romans 6:16; 1 Corinthians 3:16 alibi

Χριστὸς κ.τ.λ. The antithetic and rhythmical balance of these clauses suggests a well-known and well-used formula. Cf. above Romans 6:8. It is possible that we have here, too, a fragment of a hymn or confession; cf. 2 Timothy 2:8. N. the rhythmical character stops at θεῷ.

οὐκέτι� = never again dies: iterative, cf. Moulton, p. 114.

θάνατος α. κ.τ.λ. His resurrection was a triumph over the sovereignty of death (cf. Romans 5:14; 1 Corinthians 15:57) and has changed the meaning of death.
