You have some support for this contention? “Seems” meant “seems to me”?
“Originate in “admits of more meanings” than might first be apparent. Celebrating the Lord’s Nativity when the pagans are partying just seems like good marketing to me, and even good theology.
Good marketing because who doesn’t like a party?
Good theology(and evangelism) because while they celebrate the solstice of the sun which will be right back in the cellar in 52 weeks, we celebrate the rising of the Sun of Righteousness who has no setting.
You may want to do some research on what God says about incorporating pagan practices. From experience I would suspect you won’t. You still haven’t given me scripture to support the assumption of Mary. You deflect by asking more questions or changing the subject but answering that not so much.
