First, there is no war on Christmas. We should all be thankful that we live in a country where we have the freedom to worship as we please. That means everyone - Jews, Gentiles, Muslims, pagans - all have the same freedoms here. Insisting that someone honor your religion while you ignore theirs is, to me, the height of disrespect and judgement.
If you think there is a war on Christmas go into any store right now and what do you see and hear? Only Christmas music and Christmas decorations. Do those who do not celebrate it have a choice?
If you are indeed a Christian then you are familiar with these words of Jesus:
Do not judge, or you too will be judged. For in the same way you judge others, you will be judged, and with the measure you use, it will be measured to you. (NIV)
This is not a Christian nation. It is a nation of freedoms. There is freedom of religion as well as freedom from it. Will someone not saying Merry Christmas to you actually hamper your beliefs or celebration of Christmas? Jesus does not care if you say Merry Christmas - he does care that you love others as yourself - something he repeated 23 times in scripture. Love includes honor and respect.
Here are some verses from Romans 14 which I think very clearly state that we are not to disrespect others:
Accept him whose faith is weak, without passing judgement on disputable matters. The man who eats everything must not look down on him who does not, and the man who does not eat everything must not condemn the man who does, for God has accepted him.
One man considers one day more sacred than another, another man considers every day alike. Each one should be fully convinced in his own mind.
HAPPY HOLIDAYS TO ALL!!
