On the Sermon on the Mount

Augustine of Hippo (Latin: Aurelius Augustinus Hipponensis; 13 November 354 - 28 August 430), also known as St Augustine, St Austin, or St Augoustinos, was an early Christian theologian whose writings are considered very influential in the development of Western Christianity and Western philosophy. He was bishop of Hippo Regius (present-day Annaba, Algeria) located in the Roman province of Africa. Writing during the Patristic Era, he is viewed as one of the most important Church Fathers. Among his most important works are City of God and Confessions, which continue to be read widely today. Our Lord's Sermon on the Mount is a book by the 4th-5th-century saint, Augustine of Hippo. Augustine undertook this work before working on the Pauline Epistles because he considered chapters 5-7 of the Gospel of Matthew (the Sermon on the Mount) "a perfect standard of the Christian life"
