15 And every soul that eateth of a dead carcase, or of that which was torn, be it one home-born, or a stranger, he shall wash his clothes, and bathe in water, and be unclean until the even: then he shall be clean.
Here is a confirmation of the law against eating blood. They must eat no blood. But this law was ceremonial, and is now no longer in force; the coming of the substance does away the shadow. The blood of beasts is no longer the ransom, but Christ's blood only; therefore there is not now the reason for abstaining there then was. The blood is now allowed for the nourishment of our bodies; it is no longer appointed to make an atonement for the soul. Now the blood of Christ makes atonement really and effectually; to that, therefore, we must have regard, and not consider it as a common thing, or treat it with indifference.
