That's highly debatable. See The Germanization of Early Medieval Christianity[1] for a good, detailed counterexample. The reformation and counter-reformation have been likened to a re-Judaization of Christianity with good reason. Based on my reading, though, the pagan roots of Christianity run much deeper; for example, the concept of three gods, separate yet one, is completely alien to Judaism, but integral to Indo-European religion. It's not found in the Bible, but was made use of to explain the relationship between the three divinities found in the New Testament.

edit: I misunderstood you. The statement I thought I was responding to was that christianity absorbed pagan practices but not beliefs.
