The description before given of justifying faith does sufficiently manifest of what use it is in justification; nor shall I in general add much unto what may be thence observed unto that purpose. But whereas this use of it has been expressed with some variety, and several ways of it asserted inconsistent with one another, they must be considered in our passage. And I shall do it with all brevity possible; for these things lead not in any part of the controversy about the nature of justification, but are merely subservient unto other conceptions concerning it. When men have fixed their apprehensions about the principal matters in controversy, they express what concerns the use of faith in an accommodation thereunto. Supposing such to be the nature of justification as they assert, it must be granted that the use of faith therein must be what they plead for. And if what is peculiar unto any in the substance of the doctrine be disproved, they cannot deny but that their notions about the use of faith do fall unto the ground. Thus is it with all who affirm faith to be either the instrument, or the condition, or the “causa sine qua non,” or the preparation and disposition of the subject, or a meritorious cause, by way of condecency or congruity, in and of our justification. For all these notions of the use of faith are suited and accommodated unto the opinions of men concerning the nature and principal causes of justification. Neither can any trial or determination be made as unto their truth and propriety, but upon a previous judgment concerning those causes, and the whole nature of justification itself. Whereas, therefore, it were vain and endless to plead the principal matter in controversy upon every thing that occasionally belongs unto it, — and so by the title unto the whole inheritance of every cottage that is built on the premises, — I shall briefly speak unto these various conceptions about the use of faith in our justification, rather to find out and give an understanding of what is intended by them, than to argue about their truth and propriety, which depend on that wherein the substance of the controversy does consist.
Protestant divines, until of late, have unanimously affirmed faith to be the instrumental cause of our justification. So it is expressed to be in many of the public confessions of their churches. This notion of theirs concerning the nature and use of faith was from the first opposed by those of the Roman church. Afterward it was denied also by the Socinians, as either false or improper. Socin. Miscellan. Smalcius adv. Frantz. disput. 4; Schlichting. adver. Meisner. de Justificat. And of late this expression is disliked by some among ourselves; wherein they follow Episcopius, Curcellæus, and others of that way. Those who are sober and moderate do rather decline this notion and expression as improper, than reject them as untrue. And our safest course, in these cases, is to consider what is the thing or matter intended. If that be agreed upon, he deserves best of truth who parts with strife about propriety of expressions, before it be meddled with. Tenacious pleading about them will surely render our contentions endless; and none will ever want an appearance of probability to give them countenance in what they pretend. If our design in teaching be the same with that of the Scripture, — namely, to inform the minds of believers, and convey the light of the knowledge of God in Christ unto them, we must be contented sometimes to make use of such expressions as will scarce pass the ordeal of arbitrary rules and distinctions, through the whole compass of notional and artificial sciences. And those who, without more ado, reject the instrumentality of faith in our justification, as an unscriptural notion, as though it were easy for them with one breath to blow away the reasons and arguments of so many learned men as have pleaded for it, may not, I think, do amiss to review the grounds of their confidence. For the question being only concerning what is intended by it, it is not enough that the term or word itself, of an instrument, is not found unto this purpose in the Scripture; for on the same ground we may reject a trinity of persons in the divine essence, without an acknowledgment whereof, not one line of the Scripture can be rightly understood.
