18.  Moreover, the Moabites and Ammonites must not even be allowed to enter Deut. xxiii. 3. into the Church of God, I mean those sophistical, mischievous arguments which enquire curiously into the generation and inexpressible procession of God, and rashly set themselves in array against the Godhead:  as if it were necessary that those things which it is beyond the power of language to set forth, must either be accessible to them alone, or else have no existence because they have not comprehended them.  We however, following the Divine Scriptures, and removing out of the way of the blind the stumbling blocks contained in them, will cling to salvation, daring any and every thing rather than arrogance against God.  As for the evidences, we leave them to others, since they have been set forth by many, and by ourselves also with no little care.  And indeed, it would be a very shameful thing for me at this time to be gathering together proofs for what has all along been believed.  For it is not the best order of things, first to teach and then to learn, even in matters which are small and of no consequence, and much more in those which are Divine and of such great importance.  Nor, again, is it proper to the present occasion to explain and disentangle the difficulties of Scripture, a task requiring fuller and more careful consideration than our present purpose will allow.  Such then, to sum up, is our teaching.  I have entered into these details, with no intention of contending against the adversaries:  for I have already often, even if it be imperfectly, fought out the question with them:  but in order that I might exhibit to you the character of my teaching, that you might see whether I have not a share in the defence of your own, and do not take my stand on the same side, and opposed to the same enemies as yourselves.
