How did Augustine’s later theology reflect ideas he learned from St. Ambrose?

St. Augustine’s later theology was profoundly shaped by his time in Milan, where he was converted and baptized by St. Ambrose. Augustine was particularly indebted to Ambrose’s use of Catholic Neoplatonism, which provided a philosophical framework that eventually transformed Christian theology.1

Ambrose utilized the works of Greek philosophers, including the Neoplatonist Plotinus, to defend the spiritual meaning of the Old Testament through erudite philosophical allegory. By adopting this approach, Ambrose offered educated Latins a classical version of Christianity that reconciled faith with sophisticated intellectual inquiry.12

Augustine viewed Ambrose as a model bishop, and the philosophical base he encountered in Milan served as a cornerstone for his own influential contributions to the Roman Catholic Church.21
