This eBook has been formatted to the highest digital standards and adjusted for readability on all devices. Orthodoxy is a book by G. K. Chesterton that has become a classic of Christian apologetics. In the book's preface Chesterton states the purpose is to "attempt an explanation, not of whether the Christian faith can be believed, but of how he personally has come to believe it." In it, Chesterton presents an original view of Christian religion. He sees it as the answer to natural human needs, the "answer to a riddle" in his own words, and not simply as an arbitrary truth received from somewhere outside the boundaries of human experience.

On Christian Doctrine is a theological text written by Augustine of Hippo. It consists of four books that describe how to interpret and teach the Scriptures. By writing this text, Augustine set three tasks for Christian teachers and preachers: to discover the truth in the contents of the Scriptures, to teach the truth from the Scriptures, and to defend scriptural truth when it was attacked. Book One discusses enjoyment, use, interpretation, and the relation of various Christian doctrines to these concepts; Book Two discusses the types of unknown signs present in the world and defines each and presents methods for understanding the Scriptures; Book Three discusses how to interpret ambiguous literal and ambiguous figurative signs. Ambiguous signs are those whose meaning is unclear or confused; Book Four discusses the relationship between Christian truth and rhetoric, the importance of eloquence, and the role of the preacher.

This book is an attempt by Fr. Romero to share some of the scriptural and historical "evidence" that the contemporary Roman Catholic Church and the Apostolic Church founded by Jesus Christ circa 30 A. D. are one and the same. Using some of the commonly-heard misconceptions about the Catholic Faith as points of departure, Fr. Romero examines various key passages from Scripture, looks at historical documentation found in secular sources and, at the end of each chapter, presents quotes from the writings of the first generations of Christians to show that modern-day Catholic beliefs and practices have solid precedence in the beliefs and practices of the early Church.

Welcome to the Orthodox Church—its history, theology, worship, spirituality, and daily life. This friendly guide provides a comprehensive introduction to Orthodoxy, but with a twist: readers learn by making a series of visits to a fictitious church, and get to know the faith as new Christians did for most of history, by immersion. Mathews-Green provides commentary and explanations on everything from how to “venerate” an icon, the Orthodox understanding of the atonement, to the Lenten significance of tofu. It’s the perfect book for inquirers and newcomers, but even readers who have been Orthodox all their lives say they learned things they never knew before. Enjoyable, easy-to-read, and leavened with humor, Welcome to the Orthodox Church is a gracious guide to the ancient faith of the Christian East.

What does it mean to "think Orthodox"? What are the unspoken and unexplored premises and presumptions underlying what Christians believe? Orthodox Christianity is based on preserving the mind of the early Church, its phronema. Dr. Jeannie Constantinou brings her more than forty years' experience as a professor, Bible teacher, and speaker to bear in explaining what the Orthodox phronema is, how it can be acquired, and how that phronema is expressed in true Orthodox theology-as practiced by those who are properly qualified by both training and a deep relationship with Christ.

The City of God is a book of Christian philosophy written in Latin by Augustine of Hippo in the early 5th century AD. The book was in response to allegations that Christianity brought about the decline of Rome and is considered one of Augustine's most important works. Augustine wrote The City of God as an argument for the truth of Christianity over competing religions and philosophies. He argues that Christianity was not responsible for the Sack of Rome, but instead responsible for its success. Even if the earthly rule of the Empire was imperiled, it was the City of God that would ultimately triumph. As a work of one of the most influential Church Fathers, The City of God is a cornerstone of Western thought, expounding on many profound questions of theology, such as the suffering of the righteous, the existence of evil, the conflict between free will and divine omniscience, and the doctrine of original sin.
