Thus the Virgin Mary remains in the middle between Christ and humankind. For in the very moment he was conceived and lived, he was full of grace. All other human beings are without grace, both in the first and second conception. But the Virgin Mary, though without grace in the first conception, was full of grace in the second . . . . whereas other human beings are conceived in sin, in soul as well as in body, and Christ was conceived without sin in soul as well as in body, the Virgin Mary was conceived in body without grace but in soul full of grace.

Burgess, Minneapolis: Augsburg Fortress Press, 1992, p. 238. He gives further references in his footnote 22 on page 381: “Sermon on the Feast of the Immaculate Conception (December 8?) 1527. Festival Postil (Festpostille). WA 17/2:288.17-34.”)
Exodus 20:1-6 1 And God spoke all these words, saying,
2 "I am the LORD your God, who brought you out of the land of Egypt, out of the house of slavery.
3 "You shall have no other gods before me.
4 "You shall not make for yourself a carved image, or any likeness of anything that is in heaven above, or that is in the earth beneath, or that is in the water under the earth. 5 You shall not bow down to them or serve them, for I the LORD your God am a jealous God, visiting the iniquity of the fathers on the children to the third and the fourth generation of those who hate me, 6but showing steadfast love to thousands of those who love me and keep my commandments.
1 Timothy 2:5 For there is one God, and there is one mediator between God and men, the man Christ Jesus,
Jesus is the mediator, the great high priest. Not Mary.
He died for our sins. Not Mary.
We go to God through Jesus. Not to Jesus through Mary.
What utter blasphemy.
"Thus the Virgin Mary remains in the middle between Christ and humankind."
No, she's not. She's exactly where all Christians are; in Christ.
That you can find pro Roman excerpts is not surprising, but you fail to quote from later works where he has certainly CHANGED his views.
"The scholastic doctors argue about whether Christ was born from sinful or clean flesh, or whether from the foundation of the world God preserved a pure bit of flesh from which Christ was to be born. I reply, therefore, that Christ was truly born from true and natural flesh and human blood which was corrupted by original sin in Adam, but in such a way that it could be healed. Thus we, who are encompassed by sinful flesh, believe and hope that on the day of our redemption the flesh will be purged of and separated from all infirmities, from death, and from disgrace; for sin and death are separable evils.
Accordingly, when it came to the Virgin and that drop of virginal blood, what the angel said was fulfilled: “The Holy Spirit will come upon you and overshadow you” (Luke 1:35). To be sure, the Messiah was not born by the power of flesh and blood, as is stated in John ( cf. 1:13): “Not of blood nor of the will of a man, etc.” Nevertheless, He wanted to be born from the mass of the flesh and from that corrupted blood. But in the moment of the Virgin’s conception the Holy Spirit purged and sanctified the sinful mass and wiped out the poison of the devil and death, which is sin. Although death remained in that flesh on our account, the leaven of sin was nevertheless purged out, and it became the purest flesh, purified by the Holy Spirit and united with the divine nature in one Person. Therefore it is truly human nature no different from what it is in us. And Christ is the Son of Adam and of his seed and flesh, but, as has been stated, with the Holy Spirit overshadowing it, active in it, and purging it, in order that it might be fit for this most innocent conception and the pure and holy birth by which we were to be purged and freed from sin. [LW 7:12]"
