Well, sure, Luther says that, but Luther doesn't speak for all religion, or even all Christianity. There's a reason the movement he started is called “Protestantism”.

Contrast that quote from Luther and the attitude it expresses toward reason with, e.g., the Catechism of the Catholic Church (para. 159; footnotes excluded):

---

Faith and science: "Though faith is above reason, there can never be any real discrepancy between faith and reason. Since the same God who reveals mysteries and infuses faith has bestowed the light of reason on the human mind, God cannot deny himself, nor can truth ever contradict truth." "Consequently, methodical research in all branches of knowledge, provided it is carried out in a truly scientific manner and does not override moral laws, can never conflict with the faith, because the things of the world and the things of faith derive from the same God. The humble and persevering investigator of the secrets of nature is being led, as it were, by the hand of God in spite of himself, for it is God, the conserver of all things, who made them what they are."
