Pagan as in 'Non Christian'. Yule, Easther, Harvest, even the meal of unleavened bread and wine was to celebrate the gathering of a successful crop.
Beelzubub was the name of the Pagan charioteer that drove the sun across the sky and wasn't a name for Satan until the Church wanted to stem paganism in the UK.
Satan himself is modelled on 'Pan' for most of Europe and 'Herne the Hunter' for the UK, once again, a Pagan God that had been converted into a representative for Satan, not because Satan existed, but simply, once again, to persecute non-christians. Herne was the God of a Succesfull hunt, but anyone seen performing the ritual, with horns strapped to his head and 'cloven' deer feet, to represent the prey, was immediately branded as a 'Devil Worshipper'.
That is how Christianity got so big, by persecuting anyone who didn't agree with them.
Interesting fact :-
When the Catholics tried to defeat the Church of England, they referred to the churches, designed and built by Catholic Christians, as Mosques. Says a lot really
