There's a lot of evidence to suggest that Christianity was largely borrowed from previous religions.
Isn't the catholic church one of the richest organisations in the world? It's no wonder the vatican is so insecure, there's a lot of money at stake. You can hardly blame the followers for wanting the same.
Previous religions being...? Or do you specifically mean certain "branches" of Christianity such as Catholicism or Protestantism?
There is a certain amount of Judaism in Christianity because Jesus was a Jew and came first to the Jewish people (God's chosen people), before his disciples (Peter and Paul, separately) went to preach to the Gentiles (non-Jews) after his death.
To what evidence do you refer?
(Wow, religion on an internet forum - you DO know how to stir things up! Wanna include politics?)
