A year of decision. Faustus comes to Carthage and Augustine is disenchanted in his hope for solid demonstration of the truth of Manichean doctrine. He decides to flee from his known troubles at Carthage to troubles yet unknown at Rome. His experiences at Rome prove disappointing and he applies for a teaching post at Milan. Here he meets Ambrose, who confronts him as an impressive witness for Catholic Christianity and opens out the possibilities of the allegorical interpretation of Scripture. Augustine decides to become a Christian catechumen.
