Answer:
Augustine got many of his ideas about how God illuminated the universe from his interpretation of the works of Plato/Platonist.
Step-by-step explanation:
Saint Augustine had a deep belief that Platonist were the best of philosophers among all. As they not only concerned on the causes of things and the methodology of acquiring knowledge, but also on the cause of the organized universe.
The Neo-Platonism, system of philosophy and religion developed by the Plotinus's followers in early 3rd century and Philosophers like Plotinus and Porphyry had greatly influenced Saint Augustine and thus the Christianity.
