SYN.: καλός, δίκαιος. κ. properly refers to goodliness as manifested in form: ἀ. to inner excellence (cf. the cl. καλὸς κἀγαθός and ἐν καρδία κ. καὶ ἀ., Luk.8:15). In Rom.5:7, where it is contrasted with δ., ἀ. implies a kindliness and attractiveness not necessarily possessed by the δίκαιος, who merely measures up to a high standard of rectitude (cf. ἀγαθωσύνη).
