On 31st October 1517, Martin Luther published his 95 Theses against the sale of indulgences. This date symbolised the beginning of the Reformation in Europe. Almost no other historical event has changed the world like the Reformation 500 years ago. A consequence of the Reformation was the division of the Church into Protestant and Catholic denominations. Both Churches have changed within the 500 years after Luther's posting of the Theses, in many respects they have come closer together. Are there still differences between the Protestant and the Catholic Church these days at all? Could perhaps even Catholics profit from Martin Luther's personality and teaching nowadays?
