St. Paul, St. Augustine of Hippo, St. Thomas Aquinas, St. Teresa of Avila and C.S. Lewis are five well-known Christian authors. These men and women wrote on topics such as the relationship of faith and works, sacramental theology, proofs for the existence of God, divine love and Christian apologetics.
St. Paul was a convert from Judaism to Christianity, and one was one of the first Christians to spread the Gospel beyond the Jewish world to the Gentiles. He is the author of several letters in the New Testament, including the Letter to the Romans, I and II Corinthians and the Letter to the Galatians. The Romans beheaded him around 67 A.D.
St. Augustine of Hippo lived from 354 to 430. This bishop and Church Father wrote two of the great classics of Christian literature: the Confessions and City of God. His writings encompassed many fields of theology.
Like St. Augustine, St. Thomas Aquinas is one of the most famous theologians in Christianity. Living as a Dominican friar in the Medieval Christian world, Aquinas's Summa Theologica is one of the most comprehensive works of theology and philosophy in existence.
St. Teresa of Avila was a Carmelite nun in the 16th century. Her book The Interior Castle became a classic of mystical theology.
C.S. Lewis lived from 1898-1963. A member of the Church of England, he wrote for a Christian audience that extended beyond denominational differences. Among his works are the Chronicles of Narnia, Mere Christianity and the Screwtape Letters.
