How very convenient.
The Christians redefined the prior religions as 'Devil Worship' and thus heresy, and then started burning them.

Well, in my original quote, I was referring to heretics such as the Cathari, the subjects of the Albigensian Crusade. Among their heresies was the idea that Communion was invalid unless the Priest was himself pure - through confession and penance. This does not, to my mind, qualify as a "prior religion" - they were most certainly Catholic. Also, it was this Crusade that gave rise to the well known saying, "Kill 'em all and let God sort it out."
But, if you have an example of some pagan religion being defined as Devil worship, I'm still open to hearing about it.
