This chapter consists of four parts. I. The sum, utility, and necessity of this discussion, sec. 1. II. A proof that, generally speaking, the old and new dispensations are in reality one, although differently administered. Three points in which the two dispensations entirely agree, sec. 2–4. III. The Old Testament, as well as the New, had regard to the hope of immortality and a future life, whence two other resemblances or points of agreement follow—viz. that both were established by the free mercy of God, and confirmed by the intercession of Christ. This proved by many arguments, passages of Scripture, and examples, see. 5–23. IV. Conclusion of the whole chapter, where, for fuller confirmation, certain passages of Scripture are produced. Refutation of the cavils of the Sadducees and other Jews.
1. Introduction, showing the necessity of proving the similarity of both dispensations in opposition to Servetus and the Anabaptists
1. From what has been said above, it must now be clear, that all whom, from the beginning of the world, God adopted as his peculiar people, were taken into covenant with him on the same conditions, and under the same bond of doctrine, as ourselves; but as it is of no small importance to establish this point, I will here add it by way of appendix, and show, since the Fathers were partakers with us in the same inheritance, and hoped for a common salvation through the grace of the same Mediator, how far their condition in this respect was different from our own. For although the passages which we have collected from the Law and the Prophets for the purpose of proof, make it plain that there never was any other rule of piety and religion among the people of God; yet as many things are written on the subject of the difference between the Old and New Testaments in a manner which may perplex ordinary readers, it will be proper here to devote a special place to the better and more exact discussion of this subject. This discussion, which would have been most useful at any rate, has been rendered necessary by that monstrous miscreant, Servetus, and some madmen of the sect of the Anabaptists, who think of the people of Israel just as they would do of some herd of swine, absurdly imagining that the Lord gorged them with temporal blessings here, and gave them no hope of a blessed immortality.1 Let us guard pious minds against this pestilential error, while we at the same time remove all the difficulties which are wont to start up when mention is made of the difference between the Old and the New Testaments. By the way also, let us consider what resemblance and what difference there is between the covenant which the Lord made with the Israelites before the advent of Christ, and that which he has made with us now that Christ is manifested.
2. This similarity in general. Both covenants truly one, though differently administered. Three things in which they entirely agree
2. It is possible, indeed, to explain both in one word. The covenant made with all the fathers is so far from differing from ours in reality and substance, that it is altogether one and the same: still the administration differs. But because this brief summary is insufficient to give any one a full understanding of the subject, our explanation to be useful must extend to greater length. It were superfluous, however, in showing the similarity, or rather identity, of the two dispensations, again to treat of the particulars which have already been discussed, as it were unseasonable to introduce those which are still to be considered elsewhere. What we propose to insist upon here may be reduced to three heads:—First, That temporal opulence and felicity was not the goal to which the Jews were invited to aspire, but that they were admitted to the hope of immortality, and that assurance of this adoption was given by immediate communications, by the Law and by the Prophets. Secondly, That the covenant by which they were reconciled to the Lord was founded on no merits of their own, but solely on the mercy of God, who called them; and, thirdly, That they both had and knew Christ the Mediator, by whom they were united to God, and made capable of receiving his promises. The second of these, as it is not yet perhaps sufficiently understood, will be fully considered in its own place (Book 3 chap. 15–18). For we will prove by many clear passages in the Prophets, that all which the Lord has ever given or promised to his people is of mere goodness and indulgence. The third also has, in various places, been not obscurely demonstrated. Even the first has not been left unnoticed.
