This is not true, there was no Assumption of Mary, why the Catholics insist on worshipping someone who is barely mentioned in the totality of the text is beyond me. However, it comes from a mistake in the translation they made 100’s of years ago think “She” will crush his head, a long story, but there was no Assumption.

Flat out incorrect. What you're talking about in the "she will crush your head" is, as far as I know, in the Latin Vulgate only. I am not aware it is in the Septuagint, the Peshitta, or any Ethiopic or Armenian translations. If it happened like you said, the Latin Church would have made the "error" and then everybody else would have said "Balderdash, that's just your translation bub."

That's not at all what actually happened. As the manuscript tradition spread on the Assumption it was UNIVERSALLY accepted by all the Churches from Armenia to Gaul to Arabia and Ethiopia. And in fact, apparently our earliest account is in Greek: the De Obitu S. Dominae, which I am trying to track down as we speak.

Here’s an English translation. For what its worth, the feast has been celebrated in the Eastern Church since the 6th century.
