Praxeas was a Monarchian from Asia Minor. He believed in the unity of the Godhead and vehemently disagreed with any attempt at division of the personalities or personages of the Father, Son, and Holy Spirit in the Christian Church....

The resurrection from death is a strong component of the Christian faith, which the Nicene Creed, affirms stating: "We look for the resurrection of the dead, and the life of the world to come." The early Christian writers Irenaeus and Justin Martyr, in the second century, wrote against the widespread idea of their time that only the soul survived. In like manner, we have this later writing of St. Gregory of Nyssa (335-395 AD) which clearly articulates the position that a person is both soul and body and that Christ has promised to raise them both.

This classic by St. Basil the Great (329-379) gives eloquent exposition of the doctrine of the Trinity, showing how there is distinction and yet communion among the divine Persons. Although not the Spirit "God", St. Basil demonstrates that he, like the Son, shares the same nature as the Father.

One of the great early Christian writings of the second century, The Demonstration of the Apostolic Preaching is a book all true believers can learn from. In writing to his friend, Irenaeus unfolds the Christian faith by quoting extensively from the Old Testament.

St. Gregory of Nyssa (AD 335 - 395), the great theologian and bishop of Nyssa, turned his considerable skill to finishing the work that his brother St. Basil the Great had started on the creation of the world (the Hexaemeron). The result is this book, which examines how humans are formed as a "mean between the divine and brute beasts".

The Republic poses questions that endure: What is justice? What form of community fosters the best possible life for human beings? What is the nature and destiny of the soul? What form of education provides the best leaders for a good republic? What are the various forms of poetry and the other arts, and which ones should be fostered and which ones should be discouraged? How does knowing differ from believing?

Institutes of the Christian Religion is John Calvin's seminal work on Protestant systematic theology. Highly influential in the Western world and still widely read by theological students today, it was published in Latin in 1536 and in his native French in 1541. 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.

Among the many important historical documents from the Classical world of Greece and Rome The Antiquities of the Jews by Flavius Josephus is one of the most distinctive and characterful. Josephus (37-c100 CE) set out with the clear purpose of telling the history of the Jews from the creation in Genesis to the Jewish revolt against the Romans in 66 CE. Born in Jerusalem as Yosef ben Matityahu, he rose to become a leading participant in the First Jewish Revolt (66-73 CE).

This wonderful piece of literature displays the conversation of Justin Martyr and Trypho the Jew concerning different topics of the Christian faith. Justin marvelously defends the belief in Christ with superb wisdom using the Jewish Scriptures as his foundation. Truly a work of art that will only build one's faith that Jesus is indeed the Christ - the son of God.

The City of God is one of the most important works of Christian history and philosophy ever written. The writings of St. Augustine are as intriguing to the casual reader as it is to Christian researchers. St. Augustine's work provides insight into Western thought and the development of Western civilizations. The City of God provides the reader with an artful contrast between earthy cities and those in heaven as a representation of the eternal struggle between good and evil. The City of God was originally penned in the early 5th century as a response to the prevalent belief that Christianity was to blame for the fall of Rome. St. Augustine is known as one of the most influential Fathers of the Catholic Church. Born November 13, 354, Augustine would eventually be recognized as a Saint by the Catholic Church, the Eastern Christian Church, and the Anglican Communion.

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 Catechism of Trent was published in 1566. It was commissioned by the Council of Trent during the period of the counter-Reformation. The document's main task was to clarify the doctrine of the church for the clergy. It enjoyed widespread use within the Roman Catholic world and was considered the authoritative guide for the faithful up until the most recent catechism, which was released in 1992.

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.

Schopenhauer was just 30 when his magnum opus, Die Welt als Wille und Vorstellung, a work of considerable learning and innovation of thought, first appeared in 1818.

Much to his chagrin and puzzlement (so convinced was he of its merits), it didn't have an immediate effect on European philosophy, views and culture. It was only decades later that it was recognised as one of the major intellectual landmarks of the 19th century.

The Consolation of Philosophy is one of the key works in the rich tradition of Western philosophy, partly because of the circumstances in which it was written. Anicius Manlius Severinus Boethius (c480-c524) was of aristocratic Roman birth and became consul and then master of offices at Ravenna, one of the highest posts under the Ostrogothic Roman ruler Theodoric. But Boethius was unjustly charged with treason in 524, and this led to house arrest, then torture and execution.

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.

Meditations is former U.S. President Bill Clinton's favorite book. This audio consists of a series of personal writings by Marcus Aurelius, Roman Emperor 161-180 AD, setting forth his ideas on Stoic philosophy.

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.

Socrates, at 70+ years of age, defends himself against charges of corrupting the youth of Athens, atheism, and other false claims before accepting his fate and starting his final days on Earth.

What form of education provides the best leaders for a good republic? What are the various forms of poetry and the other arts, and which ones should be fostered and which ones should be discouraged?

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.

In My Religion, Leo Tolstoy accuses the church of hiding the true meaning of Jesus, which is to be found in the Sermon on the Mount and the call to resist evil. For Tolstoy, it is this command that has been most damaged by ecclesiastical interpretation. Tolstoy had not always been possessed of the religious ideas set forth in My Religion. For 35 years of his life, he was, in the proper acceptation of the word, a nihilist - not a revolutionary socialist but a man who believed in nothing.

Doubt as to moral and spiritual truth is distilled through a score of channels. Our seats of learning are hotbeds of agnosticism. Our literature, with rare exceptions, makes light of God and jokes about sacred things. The newspapers, the radio broadcasts, public utterances, and private conversations are steadily but surely removing the foundations of righteousness and destroying what little faith in spiritual things still remain.

The Age of Reason is formed of two parts. The first, written in 1793 in France during the revolution, is a criticism of not just the Christian church, although it is primarily focused on Christian theology, but as a rejection of all forms of organized religion, including Judaism and Islam. However, Paine's position is not one of atheism, and he begins the book with a declaration of faith in one god.

One of the most significant books ever written by a head of state, the Meditations are a collection of philosophical thoughts by the Emperor Marcus Aurelius (121 - 180 ce). Covering issues such as duty, forgiveness, brotherhood, strength in adversity and the best way to approach life and death, the Meditations have inspired thinkers, poets and politicians since their first publication more than 500 years ago. Today, the book stands as one of the great guides and companions - a cornerstone of Western thought.

The Meditations are a series of private reflections written in Greek by a Roman emperor immersed in the administration of an empire beset by wars on its frontiers and natural disasters in its interior. It is the work of a great man seeking philosophical and spiritual solace in the midst of human chaos and uncertainty. This beautiful piece of ancient literature has been the companion of many leaders over the centuries who turned to inner reflection in times of unrest. Its Stoic philosophy has been much admired and emulated.

Read by award-winning narrator Mike Vendetti, Common Sense is a pamphlet written by Thomas Paine in 1775-76 that inspired people in the Thirteen Colonies to declare and fight for independence from Great Britain in the summer of 1776. The pamphlet explained the advantages of and the need for immediate independence in clear, simple language. It was published anonymously on January 10, 1776, at the beginning of the American Revolution and became an immediate sensation.

Gaius Musonius Rufus was a Roman Stoic philosopher of the first century AD. He has been referred to as the Roman Socrates and is also remembered for being the teacher of Epictetus. He taught philosophy in Rome during the reign of Nero and so was sent into exile in 65 AD, returning to Rome only under Galba. Twenty-one of his lectures survive together with a few fragmentary notes from others, all of which are contained in this narration.

The Bahá'í faith is a recognized independent world religion attracting increasing attention--and followers--in the U.S. and around the globe as people from all walks of life search for practical spiritual direction and meaning in these deeply troubled times. Founded nearly 160 years ago, the Bahá'í Faith is today among the fastest-growing of world religions.

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.
