Will any one deny that a similar help is offered to us of the later Church in our many opportunities of avowing a fixed and personal belief? Whoever refuses to comply with an unholy custom because he belongs to Christ, whoever joins heartily in worship at the cost of making himself remarkable, whoever nerves himself to kneel at the Holy Table although he feels himself unworthy, that man has broken through many snares; he has gained assurance that his choice of God is a reality: he has shown his flag; and this public avowal is not only a sign to others, but also a token to himself. But this is only half the doctrine of this action. What he should thus openly avow was his trust (as we have shown) in atoning blood. And in the day of our peril what shall be our reliance? That our doors are trodden by orthodox visitants only? that the lintels are clean, and the inhabitants temperate and pure? or that the Blood of Christ has cleansed our conscience? Therefore (ver. 22) the blood was sprinkled with hyssop, of which the light and elastic sprays were admirably suited for such use, but which was reserved in the Law for those sacrifices which expiated sin (Lev. xiv. 49; Num. xix. 18, 19). And therefore also none should go forth out of his house until the morning, for we are not to content ourselves with having once invoked the shelter of God: we are to abide under its protection while danger lasts. And (ver. 23) upon the condition of this marking of their doorposts the Lord should _pass over_ their houses. The phrase is noteworthy, because it recurs throughout the narrative, being employed nine times in this chapter; and because the same word is found in Isaiah, again in contrast with the ruin of others, and with an interesting and beautiful expansion of the hovering poised notion which belongs to the word.[23] Repeated commandments are given to parents to teach the meaning of this institution to their children, (xii. 26, xiii. 8). And there is something almost cynical in the notion of a later mythologist devising this appeal to a tradition which had no existence at all; enrolling, in support of his new institutions, the testimony (which had never been borne) of fathers who had never taught any story of the kind. On the other hand, there is something idyllic and beautiful in the minute instruction given to the heads of families to teach their children, and in the simple words put into their mouths, “It is because of that which the Lord did for me when I came forth out of Egypt.” It carries us forward to these weary days when children scarcely see the face of one who goes out to labour before they are awake, and returns exhausted when their day is over, and who himself too often needs the most elementary instruction, these heartless days when the teaching of religion devolves, in thousands of families, upon the stranger who instructs, for one hour in the week, a class in Sunday-school. The contrast is not reassuring.
