Did Martin Luther, the founder of Protestantism, believe in the Immaculate Conception of Mary, that is, the Catholic belief that God miraculously removed all original and actual sin from her at the moment of her conception? Opinions differ. Many — even many Lutheran scholars — think that he agreed with Catholics on this point his entire life. Others, including myself, think that he did in his earlier years, but then adopted a different view, similar in some respects, but different in others. Let’s take a brief look at his complex and fascinating opinions.

The well-known Lutheran scholar Arthur Carl Piepkorn stated in a scholarly article in 1967 that “Martin Luther’s personal adherence to the Immaculate Conception of the mother of God (barring two lapses) seems to have been lifelong.” This same piece was described as a “splendid and learned summary” by the great Lutheran scholar Jaroslav Pelikan in his 1996 book, Mary Through the Ages, on page 249. Prominent Lutheran theologian Friedrich Heiler was cited in a 1959 Lutheran article stating that “Mary is for Luther immaculately conceived in this sense which the Roman church in 1854 formulated as a dogma”.

The eminent Lutheran scholar Eric W. Gritsch, one of the translators in the 55 volume set Luther’s Works, concurred, writing, “The literary evidence from Luther’s works clearly supports the view that Luther affirmed the doctrine.” He also stated that Luther affirmed Mary’s Assumption into heaven. This was in the 1992 book called The One Mediator, The Saints and Mary, Lutheran and Catholics in Dialogue VIII, written by twelve Lutheran and ten Catholic scholars. The Lutherans agreed with a common statement on page 54: “Luther himself professed the immaculate conception as a pleasing thought, though not as an article of faith.” Also, the German Lutheran Julius Kostlin, author of a famous 1883 biography, Life of Luther, stated that “The immaculate conception was firmly maintained by Luther himself.” Here are some of Luther’s own words on the topic.

In 1522, Luther opined, “She is full of grace so that she may be recognized as without any sin. God’s grace fills her with all gifts and frees her from all evil.” In a sermon from December 1527, he stated, “The other conception, namely the infusion of the soul, took place without contacting original sin. Mary the Virgin is conceived according to the body without grace, but according to the soul, she is full of grace.” This view of two conceptions, body and soul, was derived from St. Augustine and St. Thomas Aquinas. But it holds as Catholics do that Mary’s soul was always full of grace and without original sin.

In 1532, Luther affirmed, “God has formed the soul and body of the Virgin Mary full of the Holy Spirit so that she is without all sins, for she has conceived and borne the Lord Jesus.” But in 1540, his view appeared to be different: “In his conception, all of Mary’s flesh and blood was purified so that nothing sinful remained.” Note that Luther then thought that the change occurred at the conception of Jesus, not her own. The last quote persuaded me in October 2010 that Luther changed his view sometime after 1532 to a position that I describe as “the immaculate purification.”

The later Luther thought that Mary was purified at the time of the birth or conception of Jesus rather than at her own conception. Does this mean that Luther later in his life opposed the immaculate conception? If we mean the dogma as it is believed by the Catholic Church and the timing of God’s special act of grace, yes, it certainly differs. But if we mean removal of original sin, which is the essence and heart of the doctrine, then he did not deny it. But he was wrong in our eyes about its timing. Luther continued to assert that Mary was without actual sin and that she was freed from original sin at some point in her life.

Since those are the two essential elements of the immaculate conception, then we are quite justified in continuing to say that he always held the doctrine in some form. But as I noted, many prominent and influential Lutheran scholars believe that his view was identical or quite similar to the Catholic view over his entire life. Certainly, they have reasons for why they think that, and this includes a different interpretation of Luther’s words that seem to suggest otherwise. They may very well be right. As a non-scholar, I’m not in a position to disagree with them. I’m simply trying to interpret certain of Luther’s words, calling them as I see them, so to speak.

A third quite possible view is that Luther was either self-contradictory or that he vacillated, since Luther is known to have exhibited these characteristics many times and in many ways. It’s a fascinating and complex area of inquiry. In any event, even Luther’s later position, if indeed he changed his mind, is far closer to the Catholic dogma than any denominational or creed Protestant position today.

And that in and of itself is surprising and noteworthy. Viewers who want to learn more about it may want to read one or more of my linked articles. They contain a wealth of copiously documented information, much if not most of it from Protestant scholars. If you’d like to learn more about Martin Luther from a Catholic critical but fair and ecumenical perspective, two of my books may interest you. The first is called Martin Luther Catholic Critical Analysis and Praise: written in 2008. The last third of the book is devoted to Luther’s views that Catholics agree with. The title of the second book is The “Catholic” Luther: An Ecumenical Collection of his “Traditional” Utterances, from 2014. In this volume, I simply collected and categorized all the statements of Luther that I could find that were harmonious with or identical to Catholic doctrines.

Summary: Many Lutheran scholars say that Luther always held to Mary’s immaculate conception. I think he eventually held that her purification occurred at Jesus’ conception, not her own.
