Happy Hanukkah to anybody celebrating !!!
If Jesus and the Apostles and later Jewish Christians celebrated Hanukkah, what grounds could the WT have for objecting if active JW's today did likewise ?
It would not be a returning to the things of the Mosaic Law as Hanukkah was not part of that, rather it would be a returning to part of first century Christian practice.
SD7 or someone could have fun composing the article telling Dubs exactly why they cannot celebrate this rather lovely remembrance, as they cannot Christmas, in the 21st. century.
