Secondly, that, in reading the apostolic writings, we distinguish between their doctrines and their arguments. Their doctrines came to them by revelation properly so called; yet in propounding these doctrines in their writings or discourses they were wont to illustrate, support, and enforce them by such analogies, arguments, and considerations as their own thoughts suggested. Thus the call of the gentiles, that is, the admission of the Gentiles to the Christian profession without a previous subjection to the law of Moses, was imported to the apostles by revelation, and was attested by the miracles which attended the Christian ministry among them. The apostles' own assurance of the matter rested upon this foundation. Nevertheless, Saint Paul, when treating of the subject, often a great variety of topics in its proof and vindication. The doctrine itself must be received: but it is not necessary, in order to defend Christianity, to defend the propriety of every comparison, or the validity of every argument, which the apostle has brought into the discussion. The same observation applies to some other instances, and is, in my opinion, very well founded; "When divine writers argue upon any point, we are always bound to believe the conclusions that their reasonings end in, as parts of divine revelation: but we are not bound to be able to make out, or even to assent to all the premises made use of by them, in their whole extent, unless it appear plainly, that they affirm the premises as expressly as they do the conclusions proved by them." (Burnets Expos. art. 6.) CHAPTER III. THE CONNEXION OF CHRISTIANITY WITH THE JEWISH HISTORY. Undoubtedly our Saviour assumes the divine origin of the Mosaic institution: and, independently of his authority, I conceive it to be very difficult to assign any other cause for the commencement or existence of that institution; especially for the singular circumstance of the Jews adhering to the unity when every other people slid into polytheism; for their being men in religion, children in everything else; behind other nations in the arts of peace and war, superior to the most improved in their sentiments and doctrines relating to the Deity.* _________
