What Martin Luther Really Believed
As we approach the quincentenary of the Reformation, it is essential to judge its fruits by examining its roots. Martin Luther, founder of Protestantism and proponent of sola scriptura, made statements so inflammatory that even many modern Lutherans are embarrassed by them. Let us reflect on what Luther really believed and how it contradicts the fullness of the Catholic Faith.
Martin Luther on God and Christ
Luther’s own words show his disdain for God’s holiness. He wrote, “I look upon God no better than a scoundrel” and claimed Christ was guilty of “fornication” (Weimar, Vol. 1, Pg. 487; Trishreden, Vol. 2, Pg. 107). Such statements are not only offensive but heretical.
Contrary to Luther’s blasphemies, Scripture teaches: “Holy, holy, holy is the Lord of hosts! All the earth is filled with his glory!” (Isaiah 6:3, a proclamation of divine majesty).
True understanding begins by affirming God’s dignity, something Luther clearly failed to uphold. See how Sirach gives reverence to God’s law and commands.
Luther and the Ten Commandments
Shockingly, Luther said, “We must remove the Decalogue out of sight and heart” (De Wette 4, 188). He even called good works more dangerous than sin (Trischreden, Vol. VI, p. 160).
But Scripture rebukes this: “If you love me, you will keep my commandments.” (John 14:15, a divine imperative).
Good works flow from grace, not pride. Luther’s statements invert this truth. Read more in this in-depth analysis of his contradictions.
Luther on Free Will
Luther denied free will, claiming, “Man is like a horse… controlled by either God or Satan” (De Servo Arbitrio). This fatalism defies both reason and Scripture.
The Catechism teaches: “God has created man a rational being, conferring on him the dignity of a person who can initiate and control his own actions.” (CCC 1730).

Christian Living According to Luther
Luther’s doctrine included this shocking advice: “Be a sinner and sin boldly… No sin can separate us from Him, even if we were to kill or commit adultery thousands of times” (Letter No. 99, Aug. 1521).
In stark contrast, Scripture warns: “Do not be deceived: neither fornicators… nor thieves… will inherit the kingdom of God.” (1 Corinthians 6:9–10).
Christ calls us to holiness, not indulgence. To learn how grace works with our efforts, explore this insight.
Luther’s Views on Jews and Violence
One of Luther’s darkest legacies includes his violent rhetoric toward Jews. He advocated burning synagogues and even drowning converts (On the Jews and Their Lies).
The Catechism condemns such hatred: “Anti-Semitism is a sin against the dignity of persons and the love of the neighbor.” (CCC 1935).
Luther’s views are not only disturbing but diabolical. Such fruits cannot be ignored when judging the tree. See how Catholic voices respond.
Marriage and Sexual Ethics
Luther taught that “no conjugal due is ever rendered without sin” (Weimar, Vol. 8, Pg. 654), and even promoted polygamy and concubinage.
The Church teaches the opposite: “The matrimonial covenant… is ordered to the good of the spouses and the procreation and education of offspring.” (CCC 1601).
Marriage is sacred, not sinful. To defend marriage, we must reject Luther’s degraded vision of human sexuality. Find more truth in biblical wisdom.
Conclusion: Why Truth Matters
Luther’s statements—often blasphemous, violent, or heretical—stand in opposition to the teachings of Christ and His Church. Many modern Protestants reject these ideas instinctively, which should lead them to reject Luther himself.
Instead of following a man who called the Holy Spirit “the devil” and promoted sin, we are called to follow Christ in truth. As Scripture reminds us: “You will know the truth, and the truth will set you free.” (John 8:32).
May all who seek truth return home to the one, holy, Catholic, and apostolic Church. For further reading, we invite you to explore more about Luther’s errors and God’s will for us all.
