Your imagination is still keen ... The Roman government and the Sanhedrin had a stake in suppressing the ‘new religion’, so it is more likely that Mary’s other children wanted to keep her death and burial out of public knowledge. Only the Catholic desperation to raise the Mother of Jesus to goddess status keeps these fool imaginings going.
I believe you are correct sir. Whenever false doctrine proliferates, even among the faithful, there are different opinions about the same issue.
Even when I was a Catholic, it was hard to put into words what I really believed. I guess I considered Mary to be almost as important as God, but only slightly less important. I worshipped her and prayed to her, so if that makes her a demigoddess, then yes, I considered her to be a demigoddess.
Of course I know, that she was a sinner, saved by faith in Christ, same as you and me, and she had lots of kids. One thing we know nothing about, because it just isn't very important, but we know nothing about Mary's grandchildren. With as many children as she had, I am sure she had numerous grandchildren.
