3. Introduction
St. Augustine of Hippo (A.D. 354 - 430) was an Algerian-
Roman philosopher and theologian of the late Roman / early
Medieval period. He is one of the most important early
figures in the development of Western Christianity, and was
a major figure in bringing Christianity to dominance in the
previously pagan Roman Empire. He is often considered the
father of orthodox theology and the greatest of the four
great fathers of the Latin Church (along with St. Ambrose, St.
Jerome and St. Gregory).
4. Unlike the later Scholastics who took Aristotle as
the classical model to be integrated into Christian
thought, Augustine developed a philosophical and
theological system which employed elements of Plato
and Neo-Platonism in support of Christian orthodoxy.
His many works profoundly influenced the medieval
worldview.
