Exodus 12:14

14.And this day shall be unto you. This is spoken of its annual celebration, which was as well a monument of their exodus as a symbol of their future deliverance. As to its being called a rite, or ordinance for ever, (edictum soeculi,) I admit that by this expression perpetuity is meant, but only such as would exist until the renovation of the Church; and the same explanation will apply to circumcision, as well as to the whole ceremonial of the Law; for although by Christ’s coming it was abolished as concerns its use, yet did it only then attain its true solidity; and therefore the difference between ourselves and the ancient people detracts nothing from this perpetual statute; just in the same way as the new Covenant does not destroy the old in substance, but only in form. A little further on, where he says, “save that which every man must eat, that only may be done of you,” verse 18; the meaning is, that they must cease from every work, except the preparation of their day’s food; and this exception is expressly made, that they may not permit themselves to violate their sacred festivals by other business.
