St. Augustine, who had tried both ways, strikingly contrasts them in his _De Utilitate credendi_, though his direct object in that work is to decide, not between Reason and Faith, but between Reason and Authority. He addresses in it a very dear friend, who, like himself, had become a Manichee, but who, with less happiness than his own, was still retained in the heresy. "The Manichees," he observes, "inveigh against those who, following the authority of the Catholic faith, fortify themselves in the first instance with believing, and before they are able to set eyes upon that truth, which is discerned by the pure soul, prepare themselves for a God who shall illuminate. You, Honoratus, know that nothing else was the cause of my falling into their hands, than their professing to put away Authority which was so terrible, and by absolute and simple Reason to lead their hearers to God's presence, and to rid them of all error. For what was there else that forced me, for nearly nine years, to slight the religion which was sown in me when a child by my parents, and to follow them and diligently attend their lectures, but their assertion that I was terrified by superstition, and was bidden to have Faith before I had Reason, whereas they pressed no one to believe before the truth had been discussed and unravelled? Who would not be seduced by these promises, and especially a youth, such as they found me then, desirous of truth, nay conceited and forward, by reason of the disputations of certain men of school learning, with a contempt of old-wives' tales, and a desire of possessing and drinking that clear and unmixed truth which they promised me?"[331:1] Presently he goes on to describe how he was reclaimed. He found the Manichees more successful in pulling down than in building up; he was disappointed in Faustus, whom he found eloquent and nothing besides. Upon this, he did not know what to hold, and was tempted to a general scepticism. At length he found he must be guided by Authority; then came the question, Which authority among so many teachers? He cried earnestly to God for help, and at last was led to the Catholic Church. He then returns to the question urged against that Church, that "she bids those who come to her believe," whereas heretics "boast that they do not impose a yoke of believing, but open a fountain of teaching." On which he observes, "True religion cannot in any manner be rightly embraced, without a belief in those things which each individual afterwards attains and perceives, if he behave himself well and shall deserve it, nor altogether without some weighty and imperative Authority."[331:2] 6.
