Every so-called "Christian" holiday is from paganism. Not one is biblical, nor did Christ ever celebrate any of them. For those who disagree, I'd like to remind them that Christ was Jewish - not pagan, or even "Christian".
Edit- Okay, Star, you got me on the St Patrick's Day thing, but overall the holidays that are considered "Christian" are not.
I guess you mean Catholic. Just another anti-Catholic remark. Why don't you learn about the true faith founded by Jesus Christ before making judgments about it first. Try reading Catechism of the Catholic Church. May God bless you and Happy St. Patrick's Day.
