12. For the priesthood being changed, or, transferred, etc. As the authority of the Law and the priesthood is the same, Christ became not only a priest, but also a Lawgiver; so that the right of Aaron, as well as of Moses, was transferred to him. The sum of the whole is, that the ministry of Moses was no less temporary than that of Aaron; and hence both were annulled by the coming of Christ, for the one could not stand without the other. By the word Law, we understand what peculiarly belonged to Moses; for the Law contains the rule of life, and the gratuitous covenant of life; and in it we find everywhere many remarkable sentences by which we are instructed as to faith, and as to the fear of God. None of these were abolished by Christ, but only that part which regarded the ancient priesthood.
For Christ is here compared with Moses; whatever then they had in common, is not to be taken to the account, but only the things in which they differ. They in common offer God’s mercy to us, prescribe the rule of a holy and godly life, teach us the true worship of God, and exhort us to exercise faith and patience, and all the duties of godliness. But Moses was different from Christ in this respect, that while the love of the Gospel was not as yet made known, he kept the people under veils, set forth the knowledge of Christ by types and shadows, and, in short, accommodated himself to the capacity of ignorant people, and did not rise higher than to puerile elements. We must then remember, that the Law is that part of the ministration which Moses had as peculiarly his own, and different from that of Christ. That law, as it was subordinate to the ancient priesthood, was abolished when the priesthood was abolished. And Christ, being made a priest, was invested also with the authority of a legislator, that he might be the teacher and interpreter of the new covenant. At the same time, the word Law is applied, though not in its strict sense, to the Gospel; but this impropriety of language is so far from having anything harsh in it, that on account of the contrast it adds beauty to the sentence, as we find in the seventh chapter of the Epistle to the Romans
Moreover, the impiety of the Pope is extremely arrogant, who has inserted this article in his decretals, that he himself is now invested with the same authority as Aaron formerly had, because the Law and also the priesthood have been transferred to him. We see what the Apostle says; he maintains that ceremonies have ceased since the time when Christ came forth with command to proclaim the new covenant. It is then absurd hence to conclude, that anything has been transferred to the ministers of Christ; for Christ himself is alone contrasted here with Moses and Aaron. Under what pretext then can Antichrist arrogate to himself any such authority? I do not indeed speak now for the sake of disproving so gross an arrogance; but it is worth while to remind readers of this sacrilegious audacity, that they may know that this notorious servant of the servants of Christ wholly disregards the honor of his Master, and boldly mangles the Scriptures, that he may have some cloak for his own tyranny.
