Martin Luther
Martin Luther was a German theologian and priest whose Ninety-Five Theses, criticizing practices of the Catholic Church, sparked the Protestant Reformation and permanently altered the course of Christianity.
A list of scholarly objections nailed to a single church door, aided by the recently invented printing press, spread across Europe far faster than anyone, including its author, could have anticipated.
A Troubled Monk
Luther was an Augustinian monk and professor of theology who grew increasingly troubled by the Catholic Church's practice of selling indulgences — payments believed to reduce punishment for sins — viewing the practice as both theologically unsound and spiritually corrupt.
The Ninety-Five Theses
In 1517, Luther famously (according to tradition) nailed his Ninety-Five Theses, a formal list of objections to Church practices, to the door of All Saints' Church in Wittenberg — a scholarly challenge intended to spark academic debate.
Spread by the Printing Press
Aided by the recently invented printing press, copies of Luther's theses spread with unprecedented speed across Germany and beyond, transforming what might otherwise have remained a local theological dispute into a continent-wide religious movement.
Excommunication and Defiance
Luther was formally excommunicated by the Pope in 1521 after refusing to recant his views, famously declaring at the Diet of Worms that he could not act against his conscience, a moment of defiance that became central to Reformation mythology.
Translating Scripture
Luther translated the Bible into German, making scripture directly accessible to ordinary people rather than only clergy trained in Latin, and his broader teachings launched the Protestant Reformation, ultimately giving rise to numerous Protestant denominations that continue worldwide today.
