This year marks the 500th anniversary of the unofficial beginning of the Protestant Reformation. October 31st, 1517 is the date of Martin Luther's nailing his 95 Theses to the church door in Wittenberg, Germany. Although the Reformation had its faults, it still matters. It matters all these years later because the Gospel of Jesus Christ still matters.
It's popular today within many Christian circles in the USA to act as if the differences between Catholicism and Biblical Christianity aren't that significant. Excuse me, but they are still extremely significant. That's because Rome has not changed its dogma since the time of the Reformation. The reality is that Rome doesn't change. In the Middle Ages it offered a works-based salvation, and it still does today.
God used the Protestant Reformation to rescue the Gospel from the clutches of Rome. The Reformers did something that was novel at the time: they looked in the Bible to see what it had to say about salvation. What they found was justification by grace alone through faith alone. Let me repeat: they found grace in the Biblical Jesus Christ.
Today many of us have multiple copies of the Bible that we can read whenever we want. The situation was far different 500 years ago. Most folks couldn't read, and they certainly didn't have Bibles. They relied on Roman-bought priests to tell them what to believe. What the common man received was a bunch of Latin hogwash dressed up in hocus pocus. It was tradition wrapped in ceremony dressed up in, to quote that famous theologian Han Solo, "simple tricks and nonsense."
The Reformation is not about Martin Luther. The Reformation is about Jesus Christ. God has revealed His Son, the God-Man Jesus Christ, to us in the pages of scripture. What we know about Jesus we know from the Bible. Frankly, everything we know about Christ comes from scripture. Additionally, the best way to abide with Jesus is through the Bible.
The Gospel matters because Jesus Christ matters. The Reformation will not stop mattering until the Gospel stops mattering. That, of course, will never happen because Jesus is the One and only who offers true salvation: by grace alone through faith alone.
