Today is the anniversary of the day when Martin Luther posted his 95 theses on the door of the Castle Church in Wittenburg, Germany. This event took place on October 31, 1517 and launched the Protestant Reformation. Christians should be thankful for the way God used Martin Luther. The two doctrines he is most known for are sola scriptura and sola fida, which teach that Scripture alone is our sole authority and that salvation is by grace through faith in Jesus Christ and not by works.
