Tradition
St. Augustine
Reply to Faustus the Manichaean
Chapter 13
Faustus asserts that even if the Old Testament could be shown to contain predictions, it would be of interest only to the Jews, pagan literature subserving the same purpose for Gentiles. Augustine shows the value of prophesy for Gentiles and Jews alike.
