In due sequence we must now consider the Old Law; and (1) The Law itself; (2) Its precepts. Under the first head there are six points of inquiry:
(1) Whether the Old Law was good?
(2) Whether it was from God?
(3) Whether it came from Him through the angels?
(4) Whether it was given to all?
(5) Whether it was binding on all?
(6) Whether it was given at a suitable time?
