Does it matter? I'm not an apologist. All that matters is that access to pleasure and satisfaction of an individual is entirely subject to the will of a greater being, should he exist.
Okay, let's assume that pleasure and satisfaction is subject to the Will of God.
It still brings the same question up: what reasons do you find that it is your particular religion which speaks His Will?
Stirner's position is correct, except it strictly applies after the fall. According to the Philokalia, man gaining the "knowledge of good and evil", meant carnal good and evil, that is, pleasure and pain. Man "knowing" these didn't mean he didn't the faculties before, but that he gave himself over to them ("knowing" in Hebrew was also the word for raping or sex in general). Once he did, instead of corporeal pleasure and pain being harmonious with the spirit, they became overlords of him and he became enslaved to them (thus they were no longer corporeal, but carnal).
Stirner is entirely correct: Christians are "involuntary egoists". They are enslaved to egoism, a condition of the fall.
But the whole point of Christianity is to transcend the enslavement to carnal good and evil (pleasure and pain) which Stirner points out we are inescapably bound by. So Stirner's argument for voluntary egoism rests on the fall as some sort of eternal state, whereas Christianity considers the fall to be unnatural.
Who are you and why do I keep seeing this exact same thread in multiple boards?
First, it probably is the Catholic God due to miracles like Lanciano happening in the Catholic Church. As such, he is the God of Bible and therefore infinite love, which is important ( >inb4 Hell: Hell is foremost the state of exclusion from God, which is the worst that can happen to a human)
