An intriguing claim that I think has a lot of merit:
The historical debate about the genealogy of modern atheism continues amongst historians and theologians, blaming various figures such as Duns Scotus, Francisco Saurez, the deists, René Descartes, and many others. I don’t doubt that some of these figures may have contributed in one way or another, but I remain persuaded, at least for the moment, that the main culprit is really Martin Luther.Now, I say this as a convinced Protestant. I agree 100% with Luther’s sola scriptura. But I think it was probably the cause of atheism. To boil it down: Luther raised the possibility of a Christianity not founded on Papal (or at least clerical, in Councils) primacy, but based on the individual scholar/Christian reading the scriptures for themselves. Unfortunately, those who agreed with Luther on this starting point failed to present a unified front on several of the important issues in theology and ethics, with the result of the (in)famous fragmentation of Protestantism. This fragmentation became (at least perceived to be; see below) violent with the Wars of Religion, with the result that philosophers started to look for a grounding for politics and ethics outside of any kind of theology. This led to a distinctively modern kind of foundationalism, which, combined with a judgment that there was no good evidence for Christianity, led to atheism.
