I don’t find any prophect that talks about a “mark of mammon” either. In any case, the “mark of mammon” they show in the article has only one circle, so whatever that mark on the kid is, it has nothing to do with the symbol they’re showing.
Personally, I find it interesting that "the Symbol of Mammon the sign of the Devils first born" appears on a child in Britain at a time when the... Church of England will consider getting rid of mention of the devil in its baptismal ritual.
But I am not here to convince you about that either - which at least is making sense "...Assuming it has some supernatural origin..." than your non supported Celtic Cross idea.
The mother in this article said people are telling her... “its the Symbol of Mammon the sign of the Devils first born”.
She didn’t say people are telling her... “its the Symbol of the Celtic Cross”.
But you are free to keep running interference for Satan... you might want to consider if that is going to work out well for you...
In any case, the mark of mammon they show in the article has only one circle, so whatever that mark on the kid is, it has nothing to do with the symbol theyre showing.Maybe Satan should put a watermark or hologram tamper proof label on it?
