Saint Augustine of Hippo, one of the most influential theologians and philosophers in Western Christian thought, was born on November 13, 354, in Tagaste, in present-day Algeria. He is best known for his works that explore the nature of God, human existence, and the relationship between faith and reason. Augustine's early life was marked by a quest for truth, which led him through various philosophical schools before ultimately converting to Christianity at the age of 32, significantly shaping his later works.
Augustine's seminal writings include "Confessions" and "The City of God." In "Confessions," he reflects on his own life, exploring themes of sin, redemption, and the grace of God. This autobiographical text laid the groundwork for future Christian thought on personal faith and morality. "The City of God" addresses the relationship between the Christian community and worldly powers, emphasizing the distinction between the eternal city of God and the transient nature of earthly cities.
