No, just one who can read the Bible and understand that truth contradicts church traditions in many, many cases. It is, or should be common knowledge that Dec. 25 has NOTHING to do with anything Christian, but is the observance of Saturnalia, and that nearly all of the trappings of xmas are pagan. The OT believers were warned against most of these symbols and practices.
One should not mistake NT grace for the license to practice paganism.
Would putting a new name on Halloween change the fact that it is a pagan observance with very dark spiritual connotations?
