The history of modern Christianity concerns the Christian religion from the beginning of the 15th century to the end of World War II. It can be divided into the early modern period and the late modern period.

This book calls into question many of the facets of modern Christian understanding. It scripturally challenges the roots of the holidays, rituals, and doctrines of the church. Through historical documents, and more importantly, scripture itself, this work exposes the many falsities and pagan practices of modern Christianity. This book is a call to return to the truth of scripture, and a scripturally based warning to spurn the traditions of men in favor of the commandments of the Creator.
