Luther identified the greatest danger to Christianity. Martin Luther
had one thing right. He said that to beleive in god required faith,
not reason. Reason, he said was the enemy of faith. which had to be
trampled underfoot.

Reason is the Devil's greatest whore; by nature and manner of being
she is a noxious whore; she is a prostitute, the Devil's appointed
whore; whore eaten by scab and leprosy who ought to be trodden under
foot and destroyed, she and her wisdom ... Throw dung in her face to
make her ugly. She is and she ought to be drowned in baptism... She
would deserve, the wretch, to be banished to the filthiest place in
the house, to the closets.
Martin Luther, Erlangen Edition v. 16, pp. 142-148

It all a matter of choice, either live a life or rationality and
reason, or believe in god.

I choose reason. I will embrace the whore of the Devil, though she be
eaten by leprosy. I will bear her up to avoid the tramping feet of the
ignorant hoards of Christians and Moslems who have throughout history
tried to suppress her. If she bears scabs and is wretched it is
because of the indignities and wounds she has suffered from the blind
stupidity of Abrahamic faith.

The concepts of god and the practices of religion will not and cannot
submit to reason. All the rituals are unreasonable, the beliefs
unconscionable; the basis without evidence. Faith bolsters the
infantile and tragic delusion that the majority of humans suffer
under.
