The remembrance of their coming out of Egypt must also be perpetuated: "Remember this day, v. 3. Remember it by a good token, as the most remarkable day of your lives, the birthday of your nation, or the day of its coming of age, to be no longer under the rod." Thus the day of Christ's resurrection is to be remembered, for in it we were raised up with Christ out of death's house of bondage. The scripture tells us not expressly what day of the year Christ rose (as Moses told the Israelites what day of the year they were brought out of Egypt, that they might remember it yearly), but very particularly what day of the week it was, plainly intimating that, as the more valuable deliverance, and of greater importance, it should be remembered weekly.
And elsewhere on Acts 12.4:
He would do this after Easter, meta to pascha—after the passover, certainly so it ought to be read, for it is the same word that is always so rendered; and to insinuate the introducing of a gospel-feast, instead of the passover, when we have nothing in the New Testament of such a thing, is to mingle Judaism with our Christianity.
