injunction, in which he predicts rhetorically the future backsliding of the people so as to impress it vividly on their imagination. (17) I say that Moses spoke of himself in order to lend likelihood to his prediction, and not as a prophet by revelation, because in verse 21 of the same chapter we are told that God revealed the same thing to Moses in different words, and there was no need to make Moses certain by argument of God's prediction and decree; it was only necessary that it should be vividly impressed on his imagination, and this could not be better accomplished than by imagining the existing contumacy of the people, of which he had had frequent experience, as likely to extend into the future. (18) All the arguments employed by Moses in the five books are to be understood in a similar manner; they are not drawn from the armoury of reason, but are merely modes of expression calculated to instil with efficacy, and present vividly to the imagination the commands of God. (19) However, I do not wish absolutely to deny that the prophets ever argued from revelation; I only maintain that the prophets made more legitimate use of argument in proportion as their knowledge approached more nearly to ordinary knowledge, and by this we know that they possessed a knowledge above the ordinary, inasmuch as they proclaimed absolute dogmas, decrees, or judgments. (20) Thus Moses, the chief of the prophets, never used legitimate argument, and, on the other hand, the long deductions and arguments of Paul, such as we find in the Epistle to the Romans, are in nowise written from supernatural revelation. (21) The modes of expression and discourse adopted by the Apostles in the Epistles, show very clearly that the latter were not written by revelation and Divine command, but merely by the natural powers and judgment of the authors. (22) They consist in brotherly admonitions and courteous expressions such as would never be employed in prophecy, as for instance, Paul's excuse in Romans xv:15, "I have written the more boldly unto you in some sort, my brethren." (23) We may arrive at the same conclusion from observing that we never read that the Apostles were commanded to write, but only that they went everywhere preaching, and confirmed their words with signs. (24) Their personal presence and signs were absolutely necessary for the conversion and establishment in religion of the Gentiles; as Paul himself expressly states in Rom. i:11, "But I long to see you, that I may impart to you some spiritual gift, to the end that ye may be established."
