Adventists don’t celebrate Christmas

I think you may be referring to Jehovah’s Witness on those two doctrines. But JW’s and SDA’s do both believe Jesus is the Archangel Michael. They also both taught that Jesus has already returned to earth (invisibly of course). They had to come up with some explanation for their false prophecies not coming true. I believe the SDA predicted Christ’s return in the 1800’s and the JW’s in 1914.
I’ve just been reading the two links you provided. It is amazing how much cults have in common.
Adventists do not believe that there would be just 144,000 in Heaven. If you read Revelations chapter 7, there are 144,000 that are sealed. Then, there is another group that cannot be numbered.
In regards to Christmas, as it is originally a pagan holiday to celebrate the resurrection of a false god, why should it trouble you that some people, more than Adventists by the way, would not feel it as part of their faith to celebrate?
OH that is what that is all about....Christmas...Donald loves Christmas and Carson being who he is doesn’t celebrate Christmas....OK, now I got it!!! LOLOL
