Guitar's Cry
Disciple of Pan
The one Almighty God of the Jews prohibited the worship of other Pagan Gods and also any festivals associated with them.
But, contemporary ‘Christian’s’ openly, and even advocate, taking part in pagan festivals so as to attract non-Christians and younger audience who indulge in the festivities with no regard to its actual Christian meaning for people who live in countries who’s religious belief is that of ‘Christian’.
Good thing is, the opposite of Christian conversion can take place. The beliefs and customs of a people pre-Christian can live on safely and can inspire new generations to seek out alternate spiritual ideas.
It's all syncretic anyway and adds to the available symbols and customs humans can derive meaning from.
