Flee from Heresy: A Catholic Guide to Ancient and Modern Errors

• Learn what is and is not heresy
• History of over 130 heresies through the centuries
• How heresy destroys the Church, Why God allows it
• How it relates to schism, apostasy, and excommunication
• Historical and current insights from Bp. Athanasius Schneider

Society is lost and confused about God, morality, and eternity. Catholics face persecution, from outside and inside the Church, for living their Faith. Priests speak out against errors and corruption in their own hierarchy, only to be marginalized and punished by their superiors. The few bishops who remain faithful to the changeless teaching of Christ are rebuked and “canceled,” even by the pope himself, and sent into exile. Catholics longing for reverent worship are forced out of their parishes and into makeshift venues.

This is a description of the Catholic Church in the fourth century.

With similar patterns recurring in our time, one Catholic bishop is calling out to souls: “Know the errors and embrace the truth!”

In Flee from Heresy, Bishop Athanasius Schneider — raised among persecuted Catholics in the Soviet Union — offers a systematic treatment of more than 130 doctrinal errors, from ancient times down to our own day, along with English translations of the Church’s major anti-heresy documents of the past two centuries.

In this fascinating exposé, you will discover the ideological roots of our own unsteady times and be better equipped to “test all things; hold fast what is good” (1 Thess. 5:21). You will learn:

• What heresy is — and what it is not  
• A sweeping history of heresies across the centuries  
• How heresy destroys charity and the spiritual life 
• Why God allows heresy to afflict His holy Church 
• Names and categories of more than 130 doctrinal errors 
• The nefarious heresy of the anti-Christ and the anti-Mary 
• How heresy relates to schism, apostasy, and excommunication 
• Why the Virgin Mary is invoked as “Destroyer of Heresies”

Combining theological precision, superb historical insight, and concrete principles for action today, Flee from Heresy is a timely and trustworthy guide to errors old and new.
