if you dont like the old testament, and the only thing in the new that you want are jesus' teaching themselves.
then you should be calling yourself a jesus'ist or something. (this would be a very positive thing if people did it)
by the very nature of being a "chrisitian" you are accepting that it is all an organized club whilst you know you are following the leadership of your specific sect.
christianity didnt come by chance and followers, it was specifically created with a higharchy of leadership and rules that go beyond the bible. you certainly cant pick and choose the parts you want lol
