Origen was among the first to point out it was a fake and also discounted the notion that Mary did not have any other children. The Protoevangelium of James was very popular because of a desire to know of Jesus' early life.
The ignorance of Jewish life is another indication of it being a forgery.
However, the desire for a Mother goddess has always been popular.
Do you have a citation on that?
It doesn't much matter, but I'm curious.
Origen was a heretic anyway; he believed that the Devil and his angels could perhaps be saved someday, and he also castrated himself.
All I know is that when Helvidius claimed that Mary had other (biological) children in the 4th C., both Jerome and the Pope of Rome at the time violently rejected his error.
As did both Luther and Calvin, much later of course.
