I remain very unconvinced that there’s any such praying on the authentic Mary’s part in Heaven.
I’ve never read any reports of such activities nor any reports of prayer meetings in Heaven.
Worship meetings, lots of reports of those.
None of prayer meetings.
Hail Mary, full of Grace. The Lord is with thee. Blessed art thou among women & Blessed is the Fruit of thy womb, Jesus!!!
Mother Mary, pray for us; now & always!
