I had heard that Jehovah’s Witnesses don’t celebrate holidays. Boy, they sure get into the anti-celebratory mood. They are touring my neighborhood handing out pamphlets warning about how Satan rules the world and offering advice on how we can resist wicked spirits. Fun. They should learn how to go to the movies and eat Chinese food like Jewish people do.
I should’ve asked them what to do about my loud neighbors across the street.

My understanding is that they do celebrate one “holiday”: Good Friday. Wow, the day Jesus was killed — what a time to have a wing-ding.
They also don’t vote, which makes it very very hard for me not to have outright disdain for them. I had a very unpleasant encounter with a Jehovah’s Witness on election day (while I was electioneering), in which my attempts to politely close the conversation were answered with “You’re young, you don’t listen, I’ll repeat myself.”
They celebrate the day of Christ’s death because Jesus specifically said to. (Luke 22:19….”Keep doing this in remembrance of me.”) The setting was the “Lord’s supper,” first held on the day he was to die. Typically, when we observe the “remembrance” of something, we do so once a year, on the anniversary of the event. Their “celebration” is that of an observance. It’s not a party.
They don’t vote because they believe a Christian ought to be an ambassador for Christ, as 2 Cor 5:20 says. An ambassador represents the government which sent him. (God’s Kingdom, JWs feel) He doesn’t get involved in the political affairs of his host country.
Given the evil in the world today, is it really so silly to think that Satan rules it? The Bible makes a strong case for it, for example at 1 John 5:19.
