Each year, the Church celebrates Reformation Sunday on the last Sunday of October, commemorating a significant event in the history of the Reformed tradition. It was on October 31, 1517, that Martin Luther posted his 95 theses on the door of the church in Wittenberg.
At First Presbyterian Church, it also becomes a time to remember the great reformer and Father of Presbyterianism, John Calvin. His Institutes of the Christian Religion, helped shape the Presbyterian Church as it still exists.
John Knox brought Presbyterian to Scotland, and it flourished. So Reformation Sunday is also a celebration of our our Scottish roots.
