When you are in heaven, you are not present in space or time.
I look at the throne as a metaphor. Revelation 12:5 Mary was sinless according to the Fathers according her perfect cooperation with God’s grace that knows neither space nor time.
How could the God of the universe who abhors sin be born of sinful flesh? The first Protestants believed in Mary’s sinless nature.
“Mother Mary, like us, was born in sin of sinful parents, but the Holy Spirit covered her, sanctified and purified her so that this child was born of flesh and blood, but not with sinful flesh and blood. The Holy Spirit permitted the Virgin Mary to remain a true, natural human being of flesh and blood, just as we. However, he warded off sin from her flesh and blood so that she became the mother of a pure child, not poisoned by sin as we are. For in that moment when she conceived, she was a holy mother filled with the Holy Spirit and her fruit is a holy pure fruit, at once God and truly man, in one person.”[19]
