Luther had the following to say:
“We are compelled to concede to the Papists that they have the Word of GOD, that we received it from them, and that without them, we should have no knowledge of it at all.”
Martin Luther, commentary on St. John.
In his sermon of August 15, 1522, the last time Martin Luther preached on the Feast of the Assumption, he stated:
There can be no doubt that the Virgin Mary is in heaven. How it happened we do not know. And since the Holy Spirit has told us nothing about it, we can make of it no article of faith . . . It is enough to know that she lives in Christ.
The veneration of Mary is inscribed in the very depths of the human heart. (Sermon, September 1, 1522).
[She is the] highest woman and the noblest gem in Christianity after Christ . . . She is nobility, wisdom, and holiness personified. We can never honor her enough. Still honor and praise must be given to her in such a way as to injure neither Christ nor the Scriptures. (Sermon, Christmas, 1531).
No woman is like you. You are more than Eve or Sarah, blessed above all nobility, wisdom, and sanctity. (Sermon, Feast of the Visitation, 1537).
One should honor Mary as she herself wished and as she expressed it in the Magnificat. She praised God for his deeds. How then can we praise her? The true honor of Mary is the honor of God, the praise of God’s grace . . . Mary is nothing for the sake of herself, but for the sake of Christ . . . Mary does not wish that we come to her, but through her to God. (Explanation of the Magnificat, 1521).
Luther gives the Blessed Virgin the exalted position of “Spiritual Mother” for Christians:
It is the consolation and the superabundant goodness of God, that man is able to exult in such a treasure. Mary is his true Mother .. (Sermon, Christmas, 1522)
Mary is the Mother of Jesus and the Mother of all of us even though it was Christ alone who reposed on her knees . . . If he is ours, we ought to be in his situation; there where he is, we ought also to be and all that he has ought to be ours, and his mother is also our mother. (Sermon, Christmas, 1529).
Martin Luther had the belief of Mary’s Immaculate Conception, Luther’s words follow:
It is a sweet and pious belief that the infusion of Mary’s soul was effected without original sin; so that in the very infusion of her soul she was also purified from original sin and adorned with God’s gifts, receiving a pure soul infused by God; thus from the first moment she began to live she was free from all sin” (Sermon: “On the Day of the Conception of the Mother of God,” 1527).
