I have already addressed the original question. In this case I was addressing a subsequent question.
You said, I believe, that doctrine was to address the "heresy" of non belief..and that the church ALWAYS believed these things historically...I pointed out that is not true. .So were those early Christians heretics?
Actually the assumption was first taught by heretics
“The belief in the corporeal assumption of Mary is founded on the apocryphal treatise De Obitu S. Dominae, bearing the name of St. John, which belongs however to the fourth or fifth century. It is also found in the book De Transitu Virginis, falsely ascribed to St. Melito of Sardis, and in a spurious letter attributed to St. Denis the Areopagite” (Catholic Encyclopaedia).
So what does the church do with that heresy?
