Johann Eck


Johann Eck (l. 1486-1543) was a Catholic theologian and writer best known for his disputations with Martin Luther (l. 1483-1546) beginning in 1517 and continuing until his death in 1543. Eck maintained the position that, if anyone could determine truth for themselves, then there was no truth, only opinion; a claim that became central to the Counter-Reformation.
