Your notion of Christianity is a peculiar one indeed: apparently Jesus' "true ideas" had no power to last much beyong his lifetime, and indeed were largely lost to history, until the two dozen or so people who think like you do recovered the truth in the last handful of years. How lucky for the rest of us that you came along.
Jesus' "idea" had all the power to last his lifetime (eternity) and ours. Jesus didn't need the help of all that stuff, none of it is His "true idea." His true idea was....Mar 15:38 And the veil of the temple was torn in two from the top to the bottom. No more kissing the ring of pharasies or popes. The truth is there for all to read right there in the word - isn't that cool? peace
