While writing to the Manichaeans (Of the Morals of the Catholic Church Chapter 10. #16), this quote from St. Augustine pretty well rejects the attacks against the Catholic Church from numerous assailants:
…you act impertinently in trying, though vainly, to attribute to us views and opinions altogether unlike the wholesome and profitable doctrine we really hold. Nor can your silly and profane discourses be at all compared with the expositions in which learned and pious men of the Catholic Church open up those Scriptures to the willing and worthy. Our understanding of the law and the prophets is quite different from what you suppose. Mistake us no longer. We do not worship a God who repents, or is envious, or needy, or cruel, or who takes pleasure in the blood of men or beasts, or is pleased with guilt and crime, or whose possession of the earth is limited to a little corner of it. These and such like are the silly notions you are in the habit of denouncing at great length. Your denunciation does not touch us. The fancies of old women or of children you attack with a vehemence that is only ridiculous. Any one whom you persuade in this way to join you shows no fault in the teaching of the Church, but only proves his own ignorance of it.
