Pagan influences on the biblical stories of Jesus' life

[Angrboda]

How does one go about demonstrating that there was "no inspiration" from pagan religions in Christianity?

I'm genuinely curious as to how you support your claim that there is 'no truth' to claims of syncretism?

I don't say there is no truth to it.  I'm still looking for information on it I can trust.  But not everything out there on this subject is even accurate.  Having not found anything better I'm inclined to agree with above post's "nope" unless until I come across something, but I made no claim.  And I wouldn't say no elements were borrowed from paganism at all.  That would be ignorant.  I'm referring specifically to the idea that most miraculous events in Jesus' life were copied from pagan gods.

I think that would be expecting too much of syncretism without harming the core claim, that Christianity borrowed from pagan beliefs.
