I have pointed out many times that the so-called "problem of evil" is not an actual problem for Christianity. Indeed, Christianity is predicated on the existence of evil. This post, discussing how the modern academy blunders about completely failing to grasp the basic concept of evil, tends to underline that point:
Hindered by their postmodern moral relativism, many participants tended to be tentative and vague in their ruminations on moral evil (except when it concerned political conservatives). Some of the better papers concerned the theme of evil in great writers such as Kafka and Dostoevsky but left the concept of evil undefined. Only a few papers addressed the problems of the origin of evil and the essential nature of evil. One of these was a Hungarian scholar’s treatment of Plato’s thoughts on how a good deity (the Demiurge) could allow for the existence of evil. I had no idea that thinkers other than Judeo-Christian monotheists had dealt with this issue. The paper demonstrated that the existence of evil is a real intellectual puzzle that merits deeper attention than the sort of superficial, conventional moralizing on display in other presentationsAs a general rule, if your first thought concerning evil revolves around political party identities, you're totally missing the point.
