The Summa Theologica, by Thomas Aquinas, is a fundamental text in Catholic doctrine, a compendium of theology that has been studied and debated since its first publication in the 13th century. Furthermore, it has been widely regarded as one of the classics of Western philosophy, not least because, perhaps for the first time in such a systematic manner, it set out to consider the views of non-Christian figures such as Aristotle, Boethius, Muslim writers including Averroes (Ibn Rushd) and Avicenna (Ibn Sina) and the Sephardic Jewish scholar Maimonides.

The book serves as an introductory textbook on the Protestant faith for those with some previous knowledge of theology and covers a broad range of theological topics from the doctrines of church and sacraments to justification by faith alone and Christian liberty.

The Apology of Socrates, written by Plato, is a Socratic dialogue of the speech of legal self-defense which Socrates spoke at his trial for impiety and corruption in 399 BC. Specifically, the Apology of Socrates is a defense against the charges of "corrupting the youth" and "not believing in the gods in whom the city believes, but in other daimonia that are novel" to Athens.

The essence of the Christian life is communion with God. To neglect him is to neglect the fount of the living, to toil and sweat from a thirsty heart. In this collection of short essays, Tozer calls us from the deserts we wander to the life we need: Christ Jesus the Lord.

As no sensible person would make a long road trip without first consulting a map, so the person intent upon gaining Heaven should first resort to a competent guide to reach that Goal of all goals.

It is an audiobook, moreover, for all, because all are called to the devout life.

Nothing except the Resurrection of Jesus Christ is a greater miracle or wonder in human history. God becoming flesh in human history is the greatest marvel. Jesus of Nazareth was foretold in the Torah and the Prophets centuries before his appearance, and he was proved to be real and not a pretender due to his death and Resurrection. The early church grappled with all of this intellectually.

Saint Augustine's contributions to Christian theology are second to no other post-apostolic author in the whole sweep of church history. Yet along side his doctrinal treatises, Augustine tells a story of his life devoted to Christ as his only satisfaction. The Confessions is at once the autobiographical account of Augustine's life of Christian faith and at the same time a compelling theology of Christian spirituality for everyone.

The dramatic nature of Plato's dialogues is delightfully evident in Symposium. The marriage between character and thought bursts forth as the guests gather at Agathon's house to celebrate the success of his first tragedy. With wit and insight, they all present their ideas about love - from Erixymachus' scientific naturalism to Aristophanes' comic fantasy.

The majority of mortals, Paulinus, complain bitterly of the spitefulness of Nature, because we are born for a brief span of life, because even this space that has been granted to us rushes by so speedily and so swiftly that all save a very few find life at an end just when they are getting ready to live. Nor is it merely the common herd and the unthinking crowd that bemoan what is, as men deem it, an universal ill; the same feeling has called forth complaint also from men who were famous.

Written between A.D. 413 and 426, The City of God is one of the great cornerstones in the history of Christian thought, a book which is vital to the understanding of modern Western society. Augustine originally intended it to be an apology for Christianity against the accusation that the Church was responsible for the decline of the Roman Empire, which had occurred just three years earlier. Indeed, Augustine produced a great amount of evidence to prove that paganism was responsible for this event. However, by the time the work was finished, the book had taken on a larger theme.

Charged with treason under Theodoric the Great in sixth-century Rome, Boethius served one year's imprisonment, awaiting trial and eventual execution. During this time, he wrote The Consolation of Philosophy, which would go on to be one of the most popular philosophical works of all time, contributing much to medieval thought and influencing the likes of Dante and Chaucer, as well as Renaissance writers, such as Milton and Shakespeare.

It has been said that this work by Henry Scougal was "almost universally praised by the leaders of the Great Awakening". It is a piece of literature that has been used by God to influence the souls of men for the glory of Christ. Regardless of the times we live in, the great works of the men of God of old are still applicable today. In an age of lukewarm believers, we need the fire of God to burn us afresh and give us a clear vision of his holy will.

The Confessions by Saint Augustine is considered an all-time number one Christian classic. Augustine undertook his greatest piece of writing with the conviction that God wanted him to make this confession. The Confessions is, in fact, an extended poetic, passionate, intimate prayer.

From the perspective of an unbeliever, Fear and Trembling explores the paradox of faith, the nature of Christianity, and the complexity of human emotion. Kierkegaard examines the biblical story of Abraham, who was instructed to sacrifice his son Isaac, and forces us to consider Abraham's state of mind. What drove Abraham, and what made him carry out such an absurd and extreme request from God? Kierkegaard argues that Abraham's agreement to sacrifice Isaac, and his suspension of reason, elevated him to the highest level of faith.

John Milton's Paradise Lost is one of the greatest epic poems in the English language. It tells the story of the Fall of Man, a tale of immense drama and excitement, of rebellion and treachery, of innocence pitted against corruption, in which God and Satan fight a bitter battle for control of mankind's destiny.

Based on a thorough study of Greek life and civilization, of Greek literature, philosophy, and art, The Greek Way interprets their meaning and brings a realization of the refuge and strength the past can be to us in the troubled present. Miss Hamilton's book must take its place with the few interpretative volumes which are permanently rooted and profoundly alive in our literature.

This Puritan classic, first published in the late 17th century, sets forth the biblical teaching of God and his interaction in our lives.

The Gay Science (The Joyful Wisdom) is one of Nietzsche's greatest books. His wonderfully fertile mind roams over mankind, his thoughts, his emotions, his behaviour and his weaknesses with remarkable clarity, with insight - but also with humour!In this work are 383 separate paragraphs, some short, some long, but all singular observations - the epitome of his famous aphoristic style. 'Morality is the herd instinct in the individual.'

The leviathan is the vast unity of the State. But how are unity, peace, and security to be attained? Hobbes’ answer is sovereignty, but the resurgence of interest today in Leviathan is due less to its answers than its methods: Hobbes sees politics as a science capable of the same axiomatic approach as geometry.

Through a study of the way of the samurai, Nitobe identifies the seven virtues most widely recognized by the Japanese: rectitude, courage, benevolence, politeness, veracity, honor, and loyalty. In sharing these moral guidelines, handed down over generations, Nitobe gives the world unique insight into a previously unexplored code of honor.

Published in 1651, Leviathan is considered to be one of the most important works of political philosophy and a major contribution to the modern idea of central government. In the mid-17th century, England was going through a turbulent time of change and unrest, which likely shaped Hobbes' ideas on strong government. Thomas Hobbes established the social contract theory. He believed that self-government did not create the ideal state due to the human tendency to be self-serving, something he believed would eventually lead to chaos.
