Christianity Borrowed from (Other) Religions?

Question:  What percentage of Christianity do you think is borrowed from older religions and belief systems? Why? Please keep your answer short.

My Reply:

OK, how's this for brief?  NONE of Christianity is "borrowed" from older religions and beliefs.  Although, Christianity is the fulfillment of Judaism, so if you want to consider it as "borrowed", Judaism would be the closest to the answer, I suppose.
