That Jesus would celebrate all Jewish feasts, including Hanukkah or Sukkot, is no surprise whatever, and as Craig Keener points out, any suggestion to the contrary wrongly diminishes and distorts his Jewishness.

Only in modern times has it achieved its great visibility in Western countries, as a kind of counterpart to Christmas.
