To the best of my knowledge all religions but Christianity (which is different from Roman Catholicism) teach that one must work or earn their way to heaven, nirvana, or whatever the term is for the blessed hereafter. The god or prophet gives rules and admonitions that one must follow and obey so as to have a hope, a possibility of gaining eternal bliss.
With Christianity, the God of the world said here is what you would have to do – be perfect everyday of your life and this will require sacrifices and rituals to cling to in order to hope for eternal bliss. In essence at this point of the story it is the same as all other religions.
Then He did the unthinkable and said, I know you can’t do it so I will send my Son to you and He will do it and He will fulfill the required righteousness on your behalf and if you accept His work, His payment for your life – if that is all you will trust in to enter Heaven, you then can freely enter.
