The Great Apostasy: Catholicism vs. Biblical Christianity: Revealing Cultic Parallels

By Mark Swarbrick

Is Catholicism a Cult?

For centuries, Roman Catholicism has claimed to be the one true Church founded by Jesus Christ. It claims apostolic authority, an unbroken succession reaching back to Peter, and the authority to speak for Christ on earth. But what happens when those claims are examined in the light of Scripture and history? Does the evidence support them, or does it reveal something altogether different?

In The Great Apostasy: Catholicism vs. Biblical Christianity, author Mark Swarbrick presents his definitive work on Roman Catholicism. Drawing extensively from Catholicism's own official writings, historical documents, and the biblical record, he examines Rome's doctrines and practices and compares them with the teachings of Jesus and the apostles. The differences go far beyond secondary doctrines. At stake is the Gospel itself.

Among the subjects examined are: The papacy and Rome's claim to be the one true ChurchSacred Tradition and the authority of ScriptureMary, apparitions, prayers to saints, and communication with the deadThe priesthood, confession, purgatory, and the MassSalvation by grace versus the Catholic sacramental systemRelics, infant baptism, exorcism, and other Catholic practicesReligious persecution and corruption in Catholic historyThe Protestant Reformers' judgment of RomeCatholicism's historical relationship with antisemitismProphecies that foretold the rise of the great apostasyThe Scarlet Woman of Revelation and her correlation with Roman CatholicismMystery Babylon and the coming worldwide religious system
Catholicism and Bible Prophecy

The investigation does not end with doctrine and history. Swarbrick delves into Bible prophecy, examining passages that foretold the rise of the great apostasy and tracing their historical fulfillment in Roman Catholicism. He then turns to Revelation 17 and the mysterious Scarlet Woman who rides the Beast, exploring the remarkable correlation between John's prophetic description and the Roman Catholic system.

From Rome and the seven mountains to the purple and scarlet, the golden cup, the Mother of Prostitutes, the blood of the saints, and Mystery Babylon, The Great Apostasy examines the prophetic clues one by one. The evidence presents the case that Roman Catholicism is not merely a theological cult, but the historical manifestation of the great apostasy foretold in Scripture, pointing ultimately toward the final worldwide apostasy of Revelation.

Who Should Read This Book?

The Great Apostasy is written for anyone curious about Catholicism and wanting to understand what it actually teaches. Catholics, former Catholics, Protestants, and Christians with Catholic friends or family will find an accessible examination of its doctrines, history, and practices.

Its extensive use of Catholic teachings, papal claims, church councils, history, the Reformation, Scripture, and Bible prophecy also makes it valuable reference material for pastors, Bible teachers, students, apologists, and Christian researchers.

The conclusion is uncompromising: salvation is not found in a church, pope, priesthood, sacrament, tradition, Mary, or any religious institution. Salvation is found in Jesus Christ alone. Read the evidence. Compare the doctrines. Examine the history. Study the prophecy. Then decide for yourself: Is Roman Catholicism the Church of Jesus Christ, or is it the Great Apostasy?
