Yet since you tell me that among some good things it contains others which our weak human understanding cannot grasp, it seems to me rather useless to spend time in reading what is unintelligible and can therefore bear no fruit. I never could understand the fondness some people have for confusing their minds by dwelling on mystical books that merely awaken their doubts and excite their imagination, giving them a bent for exaggeration quite contrary to Christian simplicity. Let us rather read the Epistles and Gospels. Let us not seek to penetrate what mysteries they contain; for how can we, miserable sinners that we are, know the terrible and holy secrets of Providence while we remain in this flesh which forms an impenetrable veil between us and the Eternal? Let us rather confine ourselves to studying those sublime rules which our divine Saviour has left for our guidance here below. Let us try to conform to them and follow them, and let us be persuaded that the less we let our feeble human minds roam, the better we shall please God, who rejects all knowledge that does not come from Him; and the less we seek to fathom what He has been pleased to conceal from us, the sooner will He vouchsafe its revelation to us through His divine Spirit.
