ELI5: When and why did Christians stop celebrating Hannukah?
gpt
There is a popular misconception that many Jews became Christians. Actually it was pagan Greeks who by and large converted to Christianity. Many Greeks lived in Jewish areas and liked the morality but didn't want all the rules and rituals. It then spread further through pagan civilization. So not many Jews joined the new group and the new group never saw any need to perform all the Jewish traditions.
