Honestly, all in all, it doesn’t mean a thing to me if people danced in the woods or sacrificed children on the same days as Catholics celebrate Holy Days.
This is where intent comes in. I have statues in my church but I don’t pray to statues. Personally, I don’t care if others think I do. My intent is not to do that.
And if one of my Feast Days falls on a made up Wiccan holiday or a pagan holiday, who cares? It’s not about them.
Christ came to replace all the silly worship of pond scum and such. So He did.
It isn't.
Just because the Christian calendar follows the seasons in some respects doesn't mean that it is pagan: the Jewish calendar follows the seasons and no one describes it as pagan.
The slander about the calendar is part of a deliberate strategy of denigrating the apostolic faith.
