Did Christianity Borrow From Pagan Religions?

Here is one attempt to say that Christianity borrowed its ideas from Mithraism. But note the following:

• the early Christians were strongly opposed to Mithraism

• much of the Mithra cult comes from later than Christianity. It might be that Mitraism copied from Christianity but it is impossible that Christianity borrowed from Mithraism. The church fathers were upset that Mithraism was parodying Christianity.

• even where there are suggestions that Mitraism was old, very vague language is used e.g. "his origins could be much more ancient"

• parallels are spotted where they do not exist.

  • A meal of chickens, bread and wine must be Communion! Wow, as if people did not often eat bread and drink wine!

  • Being born from a rock or a living egg equals a virgin birth!

  • Was December 25 chosen as the date for Christmas because it was Mithra's birthday? No, it was the Winter solstice. And who said it was Mithra's birthday?

So, is there really any credible evidence that Christianity got its ideas from Mithraism?
