21. Furthermore, although the two Protestant parties agree that one must distinguish these two necessities which I have just indicated, namely metaphysical necessity and physical necessity, and that the first excludes exceptions even in the case of Mysteries, they are not yet sufficiently agreed upon the rules of interpretation, which serve to determine in what cases it is permitted to desert the letter of Scripture when one is not certain that it is contrary to strictly universal truths. It is agreed that there are cases where one must reject a literal interpretation that is not absolutely impossible, when it is otherwise unsuitable. For instance, all commentators agree that when our Lord said that Herod was a fox he meant it metaphorically; and one must accept that, unless one imagine with some fanatics that for the time the words of our Lord lasted Herod was actually changed into a fox. But it is not the same with the texts on which Mysteries are founded, where the theologians of the Augsburg Confession deem that one must keep to the literal sense. Since, moreover, this discussion belongs to the art of interpretation and not to that which is the proper sphere of logic, we will not here enter thereon, especially as it has nothing in common with the disputes that have arisen recently upon the conformity of faith with reason.
22. Theologians of all parties, I believe (fanatics alone excepted), agree at least that no article of faith must imply contradiction or contravene proofs as exact as those of mathematics, where the opposite of the conclusion can be reduced ad absurdum, that is, to contradiction. St. Athanasius with good reason made sport of the preposterous ideas of some writers of his time, who maintained that God had suffered without any suffering. ’Passus est impassibiliter. O ludicram doctrinam aedificantem simul et demolientem!’ It follows thence that certain writers have been too ready to grant that the Holy Trinity is contrary to that great principle which states that two things which are the same as a third are also the same as each other: that is to say, if A is the same as B, and if C is the same as B, then A and C must also be the same as each other. For this principle is a direct consequence of that of contradiction, and forms the basis of all logic; and if it ceases, we can no longer reason with
