John 4:34
Jesus saith unto them, My meat is to do the will of him that sent me, and to finish his work.
"You err in thinking that she could usher in the kingdom."
I do?
I didn't know I thought that.
I think that Mary is the mother of God, and worthy of respect for that reason.
And I think God sent her to France in the mid-1800s to solidify the faithful in the face of the secular outbreak, and sanctified the shrine to her at Lourdes by making of his mother's shrine the modern Pool of Bethsaida.
Other than that, I don't have any more theology about Mary.
And in fact, that itself isn't theology. It's more observation of empirical facts and reaction to them.
