Abstract
The last and greatest of the men revered as the "Church Fathers" was Augustine of Hippo or "St. Augustine" (A.D. 354-430). Though Christianity has produced many prominent thinkers during the past two millennia, Augustine may be the most influential Christian thinker of all time outside of the New Testament. His significant influence, especially on Western Christianity, is directly tied to his profound work as a theologian, philosopher, apologist, and church bishop.
