No in ALL abrahamic theology, whether christian, muslim or jewish, "perfect contrition" is not ascertainable no matter how hard you try. (I'm assuming contrition means feeling remorse or guilt for past sins since you did not define "contrition", correct me if i'm wrong.) You cannot have perfect remorse for past sins because you will continue to repeat these "sins" and that's a fact. If you were really sorry you would not repeat the same "sinful act" twice. You're not perfect no matter how much you delude yourselves, or pretend that you are somehow better than someone without a religious affiliation. Every christian/jew/muslim repeats the same "sinful" acts again and again: lying, cheating, stealing, taking "god's" name in vain, blaspheme, coveting your neighbors goods or their wife/husband etc... the list goes on and on. How many of the ten commandments do you violate in one day? To be fare I lie and cheat when it suits me like everyone else but little white lies to protect peoples feelings or cheating on a test are not equivalent to the hypocrisy of most christians, muslims or jews. Most christians, muslims or jews can't even follow their own religious laws let alone expect to get into this "heaven" they all crave to badly. I know because I've lived through it. I went to a catholic school from kindergarten to my senior year of high school. Those people are not who they pretend to be: they were vile, deceitful, bigoted hypocrites of the highest caliber. And don't even get me started on these ISIS mother fuckers terrorizing the middle east along with all the other degenerate terror groups of muslim ideology because you are no better than they are. The most hypocritical and moronic thing about the abrahamic religions is that you all worship the same “god-figure” yet have completely different interpretations of the same deity and the rules it has ordered you follow.
