Dawson Bethrick, a.k.a. Bahnsen Burner (a pun on the name of presuppositionalist theologian Greg Bahnsen), on his blog Incinerating Presuppositionalism, spends the time needed to fully deconstruct presup rhetoric and expose its contradictions. In this entry he discusses the fact that Christianity both claims to be ruled by an all-good God, but at the same time justifies the existence of evil.
The upshot is that Sye cannot give an unqualified “no” in response to this question. According to his worldview, there is a sense in which evil is morally justifiable. This is the Christian worldview we’re talking about. According to one of its spokesmen, the Christian worldview allows for cases in which evil is morally justifiable. In other words, as a worldview, it does not take a firm, absolute and uncompromising stand against evil, but in fact allows it under certain circumstances. In fact, the Christian worldview allows for evil in achieving some “holy purpose.” According to Christianity, then, evil is ultimately moral!
The foregoing is not some petty gripe against the Christian god (for it is merely imaginary in the first place), but a powerful and damning indictment against the Christianity as a viable worldview and the claim that it provides the necessary foundations for morality. Flat and simple, Christianity holds that evil is morally justifiable. Without this underlying premise, Christianity has no “solution” to the problem of evil; and by incorporating claims which assume this premise, apologists give away the fact that it really has no solution to the problem of evil to begin with. For by offering the view that “God has a morally sufficient reason for the evil that exists” (Bahnsen), or the view that the “ordination” of evil by the Christian god is morally justifiable (Sye Ten Bruggencate), presuppositionalists inadvertently acknowledge that evil is sourced in their god and that without the choices and actions their god has, according to Christian narratives, made, evil would never have existed in the first place. The logic is impeccable: given the premises of presuppositionalism, any act of evil can ultimately be “justified.”
