Title:
Martin_Luther

Context:
In 1542, Luther read a Latin translation of the Qur'an. He went on to produce several critical pamphlets on Islam, which he called "Mohammedanism" or "the Turk". Though Luther saw the Muslim faith as a tool of the devil, he was indifferent to its practice: "Let the Turk believe and live as he will, just as one lets the papacy and other false Christians live." He opposed banning the publication of the Qur'an, wanting it exposed to scrutiny.

Question:
What purpose would Luther have in not wanting to ban the Qur'an?

exposed to scrutiny.
