The mystery (to musthrion). See on 1 Corinthians 2:7 for this interesting word from musth (initiate), from muew, to wink, to blink. The Gnostics talked much of "mysteries." Paul takes their very word (already in common use, Matthew 13:11 ) and uses it for the gospel. Which hath been hid (to apokekrummenon). Perfect passive articular participle from apokruptw, old verb, to hide, to conceal from ( 1 Corinthians 2:7 ; Ephesians 3:9 ). But now it hath been manifested (nun de epanerwqh). First aorist passive indicative of panerow, to make manifest (panero). The construction is suddenly changed (anacoluthon) from the participle to the finite verb.
