Saint Augustine of Hippo 
The Complete Works of St. Augustine [EPUB ebook] 
Confessions, The City of God, On Christian Doctrine, Moral Treatises, Enchiridion (With Letters and Biography)

Saint Augustine is one of the most important Church Fathers. His writings influenced the development of Western philosophy and Christianity. He is recognized as a saint in the Catholic Church, the Eastern Orthodox Church, the Lutheran churches, and the Anglican Communion. Additionally, he is a preeminent Doctor of the Church and the patron of the Augustinians.
Augustine was one of the most prolific Christian authors, with more than one hundred surviving works. Among his most renowned works are Confessions, a personal account of his earlier life, and The City of God, written to restore the confidence of his fellow Christians after the sack of Rome by the Visigoths in 410. ‘On the Trinity’, in which he developed the ‘psychological analogy’ of the Trinity, is considered one of his masterpieces and arguably of more doctrinal importance than Confessions or The City of God. He also authored ‘On Free Choice of the Will’, addressing why God grants humans free will that can be used for evil.
Divided into various sections, this monumental compilation offers insights into Augustine’s life, history of the period, his philosophy and reactions to heresy, as well as his influential theological contributions.
