I don’t celebrate Christmas as Christ’s birthday. I celebrate secularly because it’s fun to see my nieces/nephews children enjoy all of the fun of the season. I love to see their eyes light up when you are able to get them something they are dreaming of.
I love them all so much - I don’t care what they celebrate. If it’s important to them it’s important to me. If they said they are celebrating Christmas,Hanukkah or The Flying Spaghetti Monster - My answer would be when/where/ and how do we throw this party. For me it doesn’t have to be some big theological debate - it’s fun so I do it.
