No one.
I don’t think she’s remotely involved in such.
I can’t think of a single Scripture
NOR
a single report from a Heavenly visit
which would affirm that she is.
I can think of several that describe a very different role for her in Heaven—namely that of helping to teach aborted babies, now children, the ways of God.
The hell-spawned caricature of the pseudo-Mary-goddess-personage farce may fit the Jr God image so carefully cultivated.
The Authentic Mary of Scripture has no interest in playing Jr God/goddess. The role of teaching children fits the authentic Mary quite well, imho.
Playing Jr God would certainly be the opposite of any kind of HEAVENLY REST for the authentic Mary.
Perhaps Roman Catholics et al do not believe that the Authentic Mary deserves her Heavenly REST?
No offense intended, but why?
I've never seen anything in Scripture that she was given this kind of a role.
