What was the Protestant Reformation about? Indulgences? Sacraments? Purgatory? The authority of the Pope? The answer is simple: Jesus. Specifically, the Reformation was about Jesus Christ’s death on the cross as our only source of forgiveness, life, and salvation. Luther said, “The cross alone is our theology.” When we look at Ephesians 1:15-23 we find what Solus Christus, or “Christ Alone” means for us!
