The history of Babel ("confusion") strikingly parallels that of the professing Church.
(1) Unity (Genesis 11:1) -- the Apostolic Church (Acts 4:32); (Acts 4:33).
(2) Ambition (Genesis 11:4) using worldly, not spiritual means (Genesis 11:3) ending in a man-made unity -- the papacy;
(3) the confusion of tongues (Genesis 11:7) -- Protestantism, with its innumerable sects.
( See Scofield) - (Isaiah 13:1).
