The subject of what Messianic Believers are to be doing for the Winter holiday season can be very controversial. On the one hand, Messianics should not really be celebrating Christmas, because it is non-Biblical and was created to be one replacement for observing the appointed times of Leviticus 23. On the other hand, should all Messianic Believers celebrate Chanukah, or the Feast of Dedication? Primarily the debate surrounds the fact that often the celebration of Chanukah can become a replacement for Christmas, and that Chanukah is not a Biblically-mandated holiday, as it is not in the Leviticus 23 list.
