This reminds of a story about a man who opens a door to a building and stands aside to allow a lady to pass.
She looks at him and says, "You don't have to open the door for me because I'm a woman."
The man replies, "I don't open the door for you because you're a lady. I do it because I am a gentleman."
There is absolutely nothing wrong with a Christian wishing anyone a Merry Christmas. It identifies you as a Christian and since we are commanded in Matthew 5:16 to let our light shine to glorify our Father in heaven, go ahead.
Let your light shine. Merry Christmas.
This season of Christmas has been celebrated as such since this nation was founded. Now, this growing secular nation wants nothing to do with “Christ” in anything. Yes, this is a concerted attempt to remove him completely from our lives. It will NOT happen at our house. All the Christmas songs sung by secular artists had no problem with Christmas. I will NEVER refer to it as the “holidays”. It is a denial of our remembrance of the Christ child who came into the world, lived a sinless life, and died on a cross for the sins of the world. That fact is not a popular one in today’s secular culture but it’s still true and though the world wants to deny him, one day every knee will bow and every tongue confess that Jesus Christ is LORD.
