Aurelius Augustine’s was a philosopher, theologian, and was bishop of the North African city of Hippo Regions for the last part of his life. Augustine is one of the most important figures in the development of Western Christianity, and is considered to be one of the church fathers. He framed the concepts of original sin and just war.
In Roman Catholicism and the Anglican Communion, he is a saint and Doctor of the Church, and the patron of the Augustinian religious order. Many Protestants, especially Calvinists, consider him to be one of the theological fathers of Reformation teaching on salvation and grace. In the Eastern Orthodox Church he is a saint, and his feast day is celebrated annually on June 15. Among the Orthodox he is called Blessed Augustine, or St. Augustine the Blessed. "Blessed" here does not mean that he is less than a saint, but is a title bestowed upon him as a sign of respect. The Orthodox do not remember Augustine so much for his theological speculations as for his writings on spirituality.
