Martin Luther on Reason

‘Whoever wants to be a Christian should tear the eyes out of his Reason.”

, Martin Luther, HT: Heretical Ideas

Also found:

Reason must be deluded, blinded, and destroyed. Faith must trample underfoot all reason, sense, and understanding, and whatever it sees must be put out of sight and … know nothing but the word of God

and
