One more reminder of how capricious this org. can be over what is and is not "pagan in origin".
For example, wedding rings are OK, birthdays are not. Torture stake is OK to picture in Watchtower graphics, conventional cross is pagan imagery.
Come to think of it, printed graphics in the Watchtower are perfectly OK, even of Jesus, but religious Icons in the catholic church are "idolatry". Not just the sculptures, but also even the roof of the sistine chapel and those painted on wood Russian icons.
Thanksgiving, which originated in early American christianity, is pagan (because the JWs did not think it up themselves). Yet, the similar and perfectly biblical "love feast" is also no longer practiced for vague unstated reasons.
