Our Lady faced on Golgotha the “complete denial” of the angel Gabriel’s promise that her son would be given the throne of David, Pope Francis palavered during his Palm Sunday homily...
Was Mary ignorant of the role her son and the son of God was assigned to play on earth?
Mary may have faced it but overcame it pretty easily when she saw her risen Son in Glory, and heard about Stephens seeing Him sitting at the right hand of God His Father. Jesus made it clear in speaking to Pilate, “My kingdom is not of this world”.
Realize that Mary had seen an angel, was a virgin that was pregnant, heard her cousin Elizabeth exclaim that John in her womb lept at her voice and let Mary know that she was the mother of her Lord, even before He was born. She saw Him at the temple expounding the Scriptures to the wise elders of the temple. She saw Him turn water into wine and on and on. Do you think it would be possible for her to doubt the eternal nature of His Kingship. I don’t think so.
