What is Reformation Day? It is the day the light of the gospel broke forth out of darkness. It was the day that began the Protestant Reformation. It was a day that led to Martin Luther, John Calvin, John Knox, and may other Reformers helping the church find its way back to God’s Word as the only authority for faith and life and leading the church back to the glorious doctrines of justification by grace alone through faith alone in Christ alone. It kindled the fires of missionary endeavors, it led to hymn writing and congregational singing, and it led to the centrality of the sermon and preaching for the people of God. It is the celebration of a theological, ecclesiastical, and cultural transformation.
So we celebrate Reformation Day. This day reminds us to be thankful for our past and to the Monk turned Reformer. What’s more, this day reminds us of our duty, our obligation, to keep the light of the gospel at the center of all we do.
