But what is “the sprinkling of blood”? A lamb was slain in every household, and the blood was smeared on the door-posts, and this was a means of warding off the Egyptian destruction. If then the blood of a lamb preserved the Jews unhurt in the midst of the Egyptians, and under so great a destruction, much more will the blood of Christ save us, who have had it sprinkled not on the door-posts, but in our souls. For even now also the Destroyer is going about in this depth of night: but let us be armed with that Sacrifice. (He calls the “sprinkling” anointing.) For God has brought us out from Egypt, from darkness, from idolatry.
