Please explain how the following request is "requiring" the "characteristics of God" of Mary:
Pray for us sinners, now and at the hour of our death.
Mary is fully human. She has none of these attributes. Any more than the saints will have after the Resurrection. The visions of Mary at Lourdes, La Sallette, and Fatima always have Mary as a messenger of the Lord, bringing warnings of what will happen to mankind if they do not return to the Him. She, like the saints, living and dead, act as His agents. But we reject the idea that the "saved" all have the same grace. Some are more gifted than others, with spiritual graces. Mary, as the mother of the Lord, as the graced one, is close to Jesus than any other human being.
Honest question: do you think the saints in eternity are still bound by the same laws of time and space that we are?
