2 Peter 2:19

ἐλευθερίαν. Doubtless that Antinomianism is indicated to which the doctrine of Grace has ever been open. Cf. Galatians 5:13. It arises from the ever-recurring confusion of liberty and license. The training of conscience is contemporaneous with the growth of Christian character. The Pauline teaching, which abrogated external legality, was open to abuse, and might easily be dangerous to recent converts from heathenism. φθορᾶς. See Mayor's note, ed. p. 175. φθορά is that gradual decay of spiritual and moral sense that follows on wilful self-indulgence. ᾧγάρ … διδούλωται. cf. Romans 6:16; Romans 8:21; John 8:34.
