3, 4. Why should we pay close attention to Bible principles when examining popular customs and celebrations?
3 Sadly, after the death of the apostles, who acted as a restraint against apostasy, so-called Christians who had no love of truth began to adopt pagan customs, celebrations, and “holy” days, which they dubbed Christian. (2 Thessalonians 2:7, 10)
Keep in mind, too, that Jehovah observed firsthand the disgusting pagan religious practices from which many popular customs originated.
