Commentary on Harmony of the Law Volume 1 Complete John Calvin
JOHN CALVIN
Now, although it was common to the race of Abraham with other nations to begin the year with the month of March; yet in this respect the reason for it was different, for it was only to the elect people that their resurrection was annually put before their eyes. But, up to that time, the Hebrews themselves had begun their year with the month of September, which is called in Chaldee Tisri, and in which many suppose that the world was created; because immediately on its creation the earth produced ripe fruits, so that its fecundity was in perfection. And still there remains among the Jews a twofold manner of dating and counting their years; for, in all matters which relate to the common business of life, they retain the old and natural computation, so that the first month is the beginning of Autumn; but, in religious matters and festivals, they follow the injunctions of Moses; and this is the legal year, beginning nearly with our month of March,314 yet not precisely, because we have not their ancient embolisms; for, since twelve circuits of the moon would not equal the sun's course, they were obliged to make an intercalation, lest, in progress of years, an absurd and enormous diversity should arise. Thence it happens that the month Nisan, in which they celebrated the Passover, begins among the Jews sometimes earlier, and sometimes later, according as the intercalation retards it.
3. Speak ye unto all. A question is asked on this passage, why, when one Lamb alone was offered in sacrifice for the reconciliation of the Church, and God was propitiated by the blood of one Christ alone, He should have commanded a lamb to be slain in every house, as if there were to be a special sacrifice for every one apart? The reply is easy; because, although all were protected from destruction by the same blood, and the general rite united them altogether into fellowship in the same expiation, yet still it was not unreasonable that, by that special application, so to speak, God would have every family separately reminded, so as to feel the grace more peculiarly conferred on itself. Thus now-a-days we have all the same baptism, whereby we are ingrafted in common into the body of Christ; yet His baptism is conferred on every individual, that they may more surely acknowledge that they are partakers in the adoption, and therefore members of the Church. God, then, in commanding them to slay a lamb in every house, did not wish to draw away the people to different grounds of hope, but only to shew them in a familiar way, that all houses were under obligation to Him, and that not only the salvation of the whole people ought to be confessed to come from Him, but that His singular blessing ought to shine forth in every family. The cause of his desiring the neighbors to be added if the number of people in one house were not, sufficient to eat the Passover, was that nothing might be left of it; and this amongst others appears to have been the chief reason why the whole lamb was to be consumed, viz., lest they should mix this sacred
