Why did Christianity become the largest religion in the world? Is it because it was misogynistic, pro-slavery, anti-science, and set on condemning those who didn't join it? This book investigates many of the misconceptions about Christianity and argues that there are good reasons this faith has become the world's largest. The book includes chapters on various misconceptions related to the history of Christianity, such as the beliefs that Jesus was a meek and mild carpenter, the Roman emperor Constantine was insincere in his Christian faith, medieval Europe was devoutly Christian, and Christianity was anti-science. Each chapter explores how the historical misconception developed and spread, and offers what we now believe to be the historical truth contradicting the fiction. Excerpts from primary source documents provide evidence for the historical misconceptions and truths and help readers to respond critically to claims about Christian history.
