The difference between a theologian and the faithful, is that for the average faithful the problem with the problem of evil is evil, but for the theologian the problem is the problem of evil. That is, if evil were to disappear from the world most people would be pleased with that outcome and not ever feel the need to give the matter another thought. However, for the theologian, even if all the evil in the world disappeared, the fact that there was evil (and therefore its logical possibility going forward) would remain just as troubling. The difference is even starker when we consider that if some theoretical solution were offered that could explain evil as compatible with G-d’s kindness, power, and knowledge, the theologian qua theologian would be satisfied even if evil persisted.
What is merely a latent theoretical dimension of the experience of other individuals is the immediate experience for the expert.
