One of the key questions the Protestant Reformation asked and answered was: how does a person get right with God? In approaching this question, the Reformers set out to rediscover and establish the bounds of essential Christianity through five declarations: sola Scriptura (Scripture alone), sola gratia (grace alone), sola fide (faith alone), solus Christus (Christ alone),and sola Deo gloria (the glory of God alone). Nate Pickowicz’s guide will help us understand not only the Reformation, but the Christian faith itself.
