FaithfulBrother asked,
does it mean that just because the Bible mentions these two events, that all birthday celebrations are forbidden?
You make a good point about lots of things, like shaving, having a pagan connection. Almost everything has a pagan connection at some point in history. Just because the 2 b'days in the Bible had a pagan connection is a pretty thin reason to ban all b'day celebrations. After all, it was the murder that was the offensive act in both of those examples, and murder is wrong whether or not it's on someone's birthday. To say that b'days are wrong based on nothing more than those 2 Bible examples is a making a giant leap that is unwarranted.
A few pagan based practices that JWs accept are,
-- Giving flowers at a funeral
-- Wearing wedding rings
-- Feeding cake at a wedding
-- Having a pinjata at a party
-- Wearing pants (Billy the Ex-Bethelite has a funny presentation on this site about pants.)
-- Owning dogs (No positive remarks made about dogs in the Bible)
-- And now, shaving
Interestingly, Watchtower has a double standard when it comes to pagan based observances. In some instances they are condemned, but in other instances they are allowed using this reasoning...
(Awake 9-22-03 p23, 24)
“A main concern is, not what the practice meant hundreds of years ago, but how it is viewed today in your area. Understandably, opinions may vary from one place to another. Hence, it is wise to avoid turning such matters into big issues.”
Yet Watchtower turns b'day celebrations into a very big issue, even though they are perfectly acceptable today, and have no meaning other than to commemorate the day of the birth of a child, which is as harmless as observing the day of a wedding anniversary.
