So why does God even need a greater plan?
He doesn't have one. or maybe he does. Depends on your intrepretation. ((Don't ignore me.))
I didn't realise we wre going to turn this into an scp discussion (yes, they have "captured" god). On another note, you said it was being controlled by the roman hierarchy, as i know, but why get rid of the badass factor considering how well it sells in civilizations such as Rome?
Remember when the Christians toke over the Roman empire, or at least their religion. Christianity sold way better than their previous religion.
Actually, one of the tenets preached in Chrsitianity is that we really shouldn't judge anyone, because it's not our place. A 'true' Christian is supposed to be nice to everyone. If a serial killer murdered your family, offer him cookies and try to help him with his issues.
Hate the sin, love the sinner. If your whole further live is dominated by your wrathfull quest to bring that one men down, then what life are you living. Is that life devestated by constant misery and hate worth it.
But what if you forgave him, and managed to continue with your life. Forgiviness is not (only) got for the sinner, but also frees the victim.
Sure this is an extreme example, but that's the gist of the Christianity (or at least one flavour of it.)
Ninjas, again. ((Don't worry guys, I forgive the ))Though ninjaing me while I write my ninjad addendum is a bit much.
