Guido de Bres is one of those guys that has been lost to history. Fortunately, however, his impact is still felt. He was a student of both John Calvin and Theodore Beza, and in 1561 he authored the Belgic Confession. This Confession was meant for the Spanish government. It was both to defend the Calvinist (showing that they were not like the radicals reforms) and to call for reformation in Spain. Instead it got him killed. In 1565 de Bres was arrested and tried before the Spanish Inquisition. He would die just a few days later.
