Cardinal Thomas Cajetan


Cardinal Thomas Cajetan (l.c. 1468-1534) was a Catholic theologian and philosopher best known for his disputations with Martin Luther (l. 1483-1546) beginning in 1518. Cajetan, a philosophical Humanist, was thought to have had the best chance of convincing Luther face-to-face of his errors and, when he failed, devoted himself to refuting Luther in writing.
