We have talked about the tremendous need for doing Teshuvah now and correcting any mistakes that we are making. A very common mistake that is done at this time of the year is Xmas. I have talked about Xtianity being idolatry, but nothing exemplifies that more than the Xmas celebration. Why because it is a pagan holiday with all its pagan rituals.
If you don't believe me, watch this short video of Pat Robertson being interviewed about the subject:
There is no way that I can control the Xtians or the world, or convince them of their sinful ways. But, how many Jews do you know who will gladly tell you how much they join their Xtian friends in this celebration? Many will tell you: it has become such a national holiday, that everyone gets involved. Is there anything wrong with giving a gift to a non-Jewish friend, or going over their house to see the tree, or having a little eggnog, after all isn't is just being nice to ones' neighbors? The answer is: it is they are pagan rituals, they are idolatrous, and according to Hashem, it is punishable (even for an Xtian).
How many times did Hashem punish populations throughout history for pagan rituals? For Jews, assimilation is punishable, but assimilation including joining in idolatrous celebration is highly punishable, according to the Torah.
Every Jew will be glad to tell you: I am not celebrating their pagan holiday, I am just making nice with a neighbor. Do you know that a Jew can go into an Islamic Mosque, but is not allowed to even step foot in a church? Why? There are idolatrous symbols in a church such as a cross, or even worse, a crucifix. There are no such items in a Mosque that would preclude a Jew being present. Going into a home completely decorated with pagan symbols (and there are many) is no different than the reason a church is forbidden. Joining in the celebration by gift giving or singing songs, or having something to eat or drink that is not kosher, or etc (there are many pitfalls to avoid), is idolatrous and punishable. It is the opposite of doing Teshuvah.
None of this is my opinion; it is very clearly written numerous times in the Torah and discussed extensively in the Oral Torah. It is probably another good reason to be in Israel (there he goes again). It is so nice to be in Jerusalem and see all the beautiful Chanukah decorations on the streets. Menorahs galore, but not one pagan symbol of an idolatrous belief.
We human beings are weak and think that we can handle the situation. But we have no idea how something affects our soul. Is being in the same room with a Xmas tree dangerous to our souls? According to our Creator, a resounding YES!!!! Why chance anything going wrong for all eternity, due to a lack of education about the Absolute Truth. I never felt a need to share Chanukah with any non-Jew, unless the person was contemplating conversion or a Noachide. I have no desire to share the rituals of paganism unless I was thinking about conversion, chas v'shalom.
There is no excuse to assimilating with idolaters. All reasons are punishable by Hashem. Don't even take a chance and think otherwise.
