agustin asked Feasy

Yes, several did, though they always baptized the idea and corrected it. The early Alexandrians, especially Clement and to some degree Origen, loved the thought that true knowledge, what they called gnosis, draws us toward the good, and Clement even pictured the mature Christian as a "true gnostic" whose knowing and loving God were one. Augustine wrestled with it more deeply and finally parted ways with Plato, because he saw from Romans 7 that we often see the good and still fail to do it, so he insisted that a rightly ordered will and grace, not knowledge alone, make us virtuous. The Eastern tradition kept the Platonic instinct alive in a purified form, teaching that knowing God transforms us, while stressing that this knowing is love and communion rather than mere intellect. So the short answer is that Christians heard Plato gladly but added that the heart, the will, and grace must come along too. I would be glad to say more about Augustine or Clement if you like.
