The festivals DO celebrate Jesus.
Jesus is Jewish and his coming Kingdom will not be stripped of it's Jewish culture.
You'll have to learn to accept that.
What on earth are you saying??! Which planet do you come from?
Jewish Festivals don't celebrate Jesus Christ (!!!) because they, the Jews, don't believe in Him, they don't accept Him as the Messiah. They say He is a liar and a deceiver.
Accept what? That you have no idea what you are talking about?
Jesus IS GOD. Tell this to a Jew.
