2017 marked the 500th anniversary of the Reformation. OSLC held a celebration in honor of the Reformation with cake! 

The Reformation was sparked in 1517 when teacher and then Catholic Priest Martin Luther nailed a list of 95 issues he had with the Catholic Church. Chief of which was their preaching of buying your way into heaven, belief that good actions were what counted towards going to heaven, and belief that only the priesthood and royalty were allowed to read the Holy Bible (at the time it was still only transcribed in Latin and the common folk at the time couldn't afford the time or money to learn a near dead language.) This lead to his excommunication, but his teachings quickly spread to other priests who were for a time hunted by the church and the Holy Roman Empire. Most priests and followers of Luther's teachings fled to Scandinavia. (This is why Norway, Sweden, Denmark, and Finland have deep ties to Lutheranism.) But after the fall of the Holy Roman Empire Lutheranism was able to thrive and spread amongst people. Nowadays the Catholic Church and the Lutheran Church are no longer such strict theological enemies. Today Lutheranism has over 80 million adherents.
