Guest Post by Zachary Dewey.
Recently a close friend of mine began his conversion to Eastern Orthodoxy. Needless to say, it was not long before our conversations shifted from the doctrines of grace and the five solas to theories of the atonement, the authority of the church, and the nature of justification.
What quickly became apparent was that if a Reformed Protestant and an Orthodox believer were ever going to maturely discuss their differences, what I needed was a much richer understanding of the church’s history and theology prior to the arrival of Martin Luther and his mallet.
So for me, this was what I needed to begin studying the vast sea of Christian Days Gone By. But what about those of us who have not had the distinct pleasure of serious conversation with Roman Catholic and Eastern Orthodox friends?
Why should the everyday Christian care about church history? Below I will offer what I believe are the three best answers to that question.
