We all know that the WTS has many times in the past changed their current stance on "scriptural" issues, changing the rules as they were. But what would be the effect if something major, but not completely counter, to their teachings were to change? For instance, the blood issue would send many straight to the doors since someone would scream about blood guilt (and anyone with sense would see it). But what if it were something simple like Birthdays?
They could easily switch their stance on Birthdays without causing a major stir, as there is nothing pagan about it, and might even be able to reason it from scripture. How quickly would the first Birthday party invitations go out?
