in their respective arguments but, overall, these theodicies—as opposed to a defense that demonstrates the existence of God and evil or hell—seek to demonstrate a framework where God's existence is plausible. It is, therefore, a logical instead of evidential answer to the problem. A theodicy explains God's reason for allowing evil, that there is a greater good that justifies such permission. Empty Hell theory Some Catholic theologians such as Karl Rahner, Gisbert Greshake, and Cardinal Hans Urs von Balthasar have at length discussed the possibility that any man may be led by a final grace to freely willed repentance if necessary at least at some point in the process of dying. This possible process is described thus by the late Munich dogmatic Prof. Michael Schmaus: If in terms of theology death is a meeting of a man with God in so far as God calls man and he answers obedience, readiness and love, it would be surprising if in the moment of dying the chances of taking position never were given, even contrary to the outward look. ... One cannot apply to experience as counter-argument, because ... what happens then in the interior and behind the physiological processes is only known by someone who experiences dying itself, and this unto its very end. We may assume that in the dissolving process of the earthly union of body and soul and with the progressing breakaway from earthly entanglements, a special awakeness accrues to man ... in which he can say yea or nay to God. Balthasar was careful to describe his opinion that Hell might be empty as merely a hope, but even this claim was rejected by most conservative Catholics, including Cardinal Avery Dulles. The Syllabus says in no. 17 that we may not (even) hope for the salvation of all non-Catholics; this seems to mean conversely that there is at least one non-Catholic in all history who will not be saved. seems to say that "many" will be reproved, which may imply hell (not some lesser purgatory). On the other hand, error no. 17 in question only speaks of those "in the true Church of Christ", which need not imply the visible Church. Roman Catholicism not only allows for the possibility that non-Catholics can be saved, and even rejected the view known as Feeneyism, which held that only people in visible communion with the Catholic Church could be saved.
