(179) The falsity of such a doctrine is shown in this very chapter, for we have shown both by reason and examples that the meaning of Scripture is only made plain through Scripture itself, and even in questions deducible from ordinary knowledge should be looked for from no other source. (180) Lastly, such a theory supposes that we may explain the words of Scripture according to our preconceived opinions, twisting them about, and reversing or completely changing the literal sense, however plain it may be. (181) Such licence is utterly opposed to the teaching of this and the preceding chapters, and, moreover, will be evident to everyone as rash and excessive. (182) But if we grant all this licence, what can it effect after all? Absolutely nothing. (183) Those things which cannot be demonstrated, and which make up the greater part of Scripture, cannot be examined by reason, and cannot therefore be explained or interpreted by this rule; whereas, on the contrary, by following our own method, we can explain many questions of this nature, and discuss them on a sure basis, as we have already shown, by reason and example. (184) Those matters which are by their nature comprehensible we can easily explain, as has been pointed out, simply by means of the context. (185) Therefore, the method of Maimonides is clearly useless: to which we may add, that it does away with all the certainty which the masses acquire by candid reading, or which is gained by any other persons in any other way. (186) In conclusion, then, we dismiss Maimonides' theory as harmful, useless, and absurd. (187) As to the tradition of the Pharisees, we have already shown that it is not consistent, while the authority of the popes of Rome stands in need of more credible evidence; the latter, indeed, I reject simply on this ground, for if the popes could point out to us the meaning of Scripture as surely as did the high priests of the Jews, I should not be deterred by the fact that there have been heretic and impious Roman pontiffs; for among the Hebrew high-priests of old there were also heretics and impious men who gained the high- priesthood by improper means, but who, nevertheless, had Scriptural sanction for their supreme power of interpreting the law. (See Deut. xvii:11, 12, and xxxiii:10, also Malachi ii:8.) (188) However, as the popes can show no such sanction, their authority remains open to very grave doubt, nor should anyone be deceived by the example of the Jewish high-priests and think that the Catholic religion also stands in need of a pontiff; he should bear in mind that the laws of Moses being also the ordinary laws of the country, necessarily required some public authority to insure their observance; for, if everyone were free to interpret the laws of his country as he pleased, no state could stand, but would for that very reason be dissolved at once, and public rights would become private rights.
