Answer 2

Martin Luther (November 10, 1483 – February 18, 1546) was a German monk,[1] theologian, and church reformer. He is also considered to be the founder of Protestantism.[2]

Luther's theology challenged the authority of the papacy by holding that the Bible is the sole source of religious authority and that all baptized Christians are a general priesthood.[3] According to Luther, salvation was attainable only by faith in Jesus as the Messiah, a faith unmediated by the church.[4] These ideas helped to inspire the Protestant Reformation and changed the course of Western civilization.

Infante Henrique of Portugal, Duke of Viseu KG (Porto, March 4, 1394 – Sagres, November 13, 1460); pron.
