Catholics and Protestants, did you know Martin Luther's deep Devotion to the Virgin Mary?
Luther indeed was quite devoted to Our Lady, and retained most of the traditional Marian doctrines which were held then and now by the Catholic Church. This is often not well-documented in Protestant biographies of Luther and histories of the 16th century,
Along with virtually all important Protestant Founders (e.g., Calvin, Zwingli, Cranmer), Luther accepted the traditional belief in the perpetual virginity of Mary (Jesus had no blood brothers), and her status as the Theotokos (Mother of God).
Probably the most astonishing Marian belief of Luther is his acceptance of Mary's Immaculate Conception, which wasn't even definitively proclaimed as dogma by the Catholic Church until 1854.
Luther held to the idea and devotional practice of the veneration of Mary and expressed this on innumerable occasions with the most effusive language.
His attitude towards the use of the "Hail Mary" prayer (the first portion of the Rosary) is illustrative. In certain polemical utterances he appears to condemn its recitation altogether, but he is only forbidding a use of Marian devotions apart from heartfelt faith, as the following two citations make clear:
Whoever possesses a good (firm) faith, says the Hail Mary without danger! Whoever is weak in faith can utter no Hail Mary without danger to his salvation. (Sermon, March 11, 1523).
Our prayer should include the Mother of God.. .What the Hail Mary says is that all glory should be given to God, using these words: "Hail Mary, full of grace. The Lord is with thee; blessed art thou among women and blessed is the fruit of thy womb, Jesus Christ. Amen!" You see that these words are not concerned with prayer but purely with giving praise and honor.. .We can use the Hail Mary as a meditation in which we recite what grace God has given her. Second, we should add a wish that everyone may know and respect her...He who has no faith is advised to refrain from saying the Hail Mary. (Personal Prayer Book, 1522).
His views of Mary as Mother of God and as ever-Virgin were identical to those in Catholicism, and his opinions on the Immaculate Conception, Mary's "Spiritual Motherhood" and the use of the "Hail Mary" were substantially the same. He didn't deny the Assumption (he certainly didn't hesitate to rail against doctrines he opposed!), and venerated Mary in a very touching fashion which, as far as it goes, is not at all contrary to Catholic piety.
Therefore, it can be stated without fear of contradiction that Luther's Mariology is very close to that of the Catholic Church today, far more than it is to the theology of modern-day Lutheranism. To the extent that this fact is dealt with at all by Protestants, it is usually explained as a "holdover" from the early Luther's late medieval Augustinian Catholic views ("everyone has their blind spots," etc.). But this will not do for those who are serious about consulting Luther in order to arrive at the true "Reformation heritage" and the roots of an authentic Protestantism. For if Luther's views here can be so easily rationalized away, how can the Protestant know whether he is trustworthy relative to his other innovative doctrines such as extrinsic justification by faith alone and sola Scriptura?
It appears, once again, that the truth about important historical figures is almost invariably more complex than the "legends" and overly-simplistic generalizations which men often at the remove of centuries—create and accept uncritically.
