In 1415, Jan Hus or John Huss was burned at the stake for believing in the Authority of the Scriptures over that of the Roman Catholic Church. He argued that Christ alone is the Head of the Church, that, motivated by the atrocities and corruptions in the church, the Popes "through ignorance and love of money" can make many mistakes, and that to question an erring Pope is to obey Christ.
While he was burning, he said "Today you will cook a goose," (Hus means goose) "but 100 years from now, will come a swan that you will neither catch nor boil!" One Hundred years after Hus' proclamation, Martin Luther, dubbed as the Swan, nailed his 95 theses to the doors of the church in Wittenberg Germany, starting the Protestant Reformation.
