“And it was at Jerusalem the feast of the dedication, and it was winter. And Jesus walked in the temple in Solomon’s porch.” – John 10:22-23
Hanukkah was called the “Dedication” during the time of Jesus Christ’s life. The quote from John’s Gospel clearly shows that Christ would have observed the feast.
I believe this is a good reason for Christians to learn more about Hanukkah and consider celebrating the holiday.
