it's ridiculous as it seems my sister C who is an evangelical conservative Christian tell me a few years ago that the Pilgrim religion was related to the Native American because the Native Americans shared their food with them on Thanksgiving, And that there is a Pagan connection there.
My initial response to this post was that you were joking, because it is difficult for me to believe that anyone would ever actually what you say your sister said. But I'm going to proceed on the assumption that you are being earnest.
Thanksgiving is a secular holiday. It is kept by all Americans regardless of their personal religious faith. But let's back up.
The holiday is associated with the story of the Pilgrims, who almost all died that first terrible winter in the new land. They were able to survive only because of the way the local Native American tribe taught them i.e. how to plant corn and stuff. In the autumn, after the harvest, they held a feast to celebrate the bounty. According to legend, members of the local tribe joined them at this meal.
So who were the Pilgrims?
They were a group of Puritans, a Christian denomination that felt the Church of England was too Catholic. At that time in England, it was illegal to be any other denomination than Church of England. So the Pilgrims ended up leaving, so that they could worship freely. (Side note--that doesn't mean they were in favor of religious freedom, only that they wanted THIER faith to be free.) So basically, the religion of the Pilgrims was CHRISTAIN, not pagan.
In what universe does having a dinner with someone mean I am part of their religion? Yes, the Native Americans were pagan, a form of animism. Although the chief did allow protestant missionaries to come speak to the tribe, he remained immovable in his rejection of Christianity. But what does that have to do with the price of tea in China, as they say. It's not as if paganism is a contagious disease -- no one becomes pagan by being in proximity with pagans.
It was President Abraham Lincoln who declared Thanksgiving to be a NATIONAL (not religious) holiday. Lincoln was not a Christian. He would say that the ten commandments were his religion. But again, his personal religion is irrelevant. Thanksgiving is part of a group of holidays that are civic, not religious, holidays like Independence day and Labor day.
You should ask your sister if she celebrates holidays like Mother's Day. I'm sure she does. Tell her that Thanksgiving is like that.
The only Christians that I know of who are opposed to holidays are the Jehovah's Witnesses. None of the evangelicals I've ever known have been opposed to any holidays. I have never in my life known an evangelical that would object to Thanksgiving based on the idea that the Pilgrims became infected with paganism.
