Marianne Deborah Williamson (born July 8, 1952) is an American self-help author, speaker, and political activist. She began her professional career as a spiritual leader of the Church of Today, a Unity Church in Warren, Michigan. Williamson has written several self-help books, including A Return to Love: Reflections on the Principles of A Course in Miracles in 1992, which became a New York Times Best Seller. She rose to prominence through frequent appearances on Oprah Winfrey's show, and becoming known as her "spiritual advisor".
Williamson ran unsuccessfully as an independent for California's 33rd congressional district in the United States House of Representatives in 2014, finishing fourth with 13.2% of the vote. She ran for the Democratic nomination for president in 2020, eventually dropping out and endorsing Bernie Sanders. She ran for president again in 2024, challenging incumbent President Joe Biden. After having suspended and restarted her campaign, Williamson ended her longshot White House bid in July 2024. She unsuccessfully campaigned for the position of DNC chair in 2025.
Williamson has been actively involved with charity work, founding such organizations as Center for Living in 1987, Project Angel Food in 1989, and the Peace Alliance in 1998. Allegations of abusive and bullying behavior toward both colleagues and staff have followed her throughout her career.
Marianne Deborah Williamson was born in Houston, Texas, on July 8, 1952. She is the youngest of three children of Samuel "Sam" Williamson, a World War II veteran and immigration lawyer, and Sophie Ann Kaplan, a homemaker and community volunteer.
Williamson was raised in an upper-middle-class family that practiced Conservative Judaism. Her family attended Congregation Beth Yeshurun. She learned about world religions and social justice at home and became interested in public advocacy when she saw her rabbi speak against the Vietnam War.
In 1965, after Williamson came home from school in the seventh grade, she recounted to her parents that her teacher supported the Vietnam War. Her father reacted by taking the family to Vietnam to help explain to Marianne why he thought that the war was wrong. She has said that through travel she "had an experience, at a young age, that people are the same everywhere."
Williamson attended Houston ISD's Bellaire High School. After graduating, she spent two years studying theater and philosophy at Pomona College in Claremont, California, where she was a roommate of future film producer Lynda Obst.
In 1973, Williamson dropped out of college and lived "a nomadic existence" during what she calls "her wasted decade".
Williamson moved to New Mexico, where she took classes at the University of New Mexico. The couple broke up a year later. Marianne then moved to Austin, Texas, where she took classes at the University of Texas. After leaving Texas, she went to New York City, intending to pursue a career as a cabaret singer; however, she has stated that she was distracted by "bad boys and good dope". Vanity Fair wrote that Williamson "spent her twenties in a growing state of existential despair." In New York, Williamson suffered from deep depression following the end of a relationship. She has said that this experience gave rise to a desire to spend the rest of her life helping people. Allegations of abusive behavior toward colleagues and staff have followed her throughout her career.
Although initially uninterested due to her Jewish faith, Williamson developed an interest in Helen Schucman's book A Course in Miracles in 1976. She explored spirituality, metaphysics, and meditation as she began reading the Course "passionately". She also reconciled the Course with her Jewishness; in her view, "A conversion to Christ is not a conversion to Christianity. It is a conversion to a conviction of the heart".
Williamson said the book was her "path out of hell", as she had been "mired in a series of unhappy love affairs, alcohol and drug abuse, a nervous breakdown, and endless sessions with therapists." The Course has often been described as a religion or pseudoreligion. Williamson disagrees, describing it as a "spiritual psychotherapy" instead of a religion.
In 1979, Williamson returned to Houston, where she ran a metaphysical bookstore coffee shop, sang Gershwin standards in a nightclub, got married and divorced "almost immediately", and underwent a "spiritual surrender".
In 1983, Williamson had what she has called a "flash" to close the coffee shop and move to Los Angeles. She rented an apartment in Hollywood, where her roommate was 17-year-old Laura Dern. Dern has stated that Williamson "held prayer groups in our living room."
Williamson's teachings stemmed from an inspirational message: "Divine love is the core and essence of every human mind." She saw this message as a remedy to misinterpretations of the Bible that, through an emphasis on sin and guilt, could lead to harm (e.g., slavery, depression, self-loathing).
As word spread about "the young woman talking about a God who loves you, no matter what," she had to rent church space to accommodate the demand to hear her speak. In 1987, she began lecturing monthly in New York. Eventually, she was invited to speak throughout the U.S. and Europe. Williamson did not charge for her lectures but had a "suggested donation" of $7 and a policy of not turning people away for lack of money. Williamson's style has been described as a "trendy amalgam of Christianity, Buddhism, pop psychology and 12-step recovery wisdom".
Williamson became the spiritual leader for the Church of Today, a Unity Church in Warren, Michigan, where she had 2,300 congregants and 50,000 television viewers. Her position also included administrative leadership; her actions as leader included booking Aerosmith's Steven Tyler, expanding the bookstore, and increasing the congregation's racial and sexual orientation diversity. As a result, the Church grew rapidly.
Williamson has written 17 books as of 2026. Seven have appeared on the New York Times bestseller list, with four reaching number one. She has sold more than three million books.
Williamson's most popular self-help work is A Return to Love: Reflections on the Principles of A Course in Miracles (1992). The book appeared on The New York Times bestseller list for 39 weeks in the "Advice, How To and Miscellaneous" category; it teaches that practicing love every day will bring more peace and fulfillment to one's life. The following quotation is the most famous quotation from the book (it is often misattributed to Nelson Mandela):Our deepest fear is not that we are inadequate. Our deepest fear is that we are powerful beyond measure. It is our light, not our darkness, that most frightens us. We ask ourselves, who am I to be brilliant, gorgeous, talented, fabulous? Actually, who are you not to be? You are a child of God. Your playing small doesn't serve the world. There's nothing enlightened about shrinking so that other people won't feel insecure around you. We are all meant to shine, as children do. We were born to make manifest the glory of God that is within us. It's not just in some of us; it's in everyone. And as we let our own light shine, we unconsciously give other people permission to do the same. As we're liberated from our own fear, our presence automatically liberates others.Oprah Winfrey said of the book, "I have never been more moved by a book than I am by this one." Winfrey bought 1,000 copies and encouraged her audience to purchase it, telling them that after reading it, she experienced 157 miracles. Williamson was a frequent guest on The Oprah Winfrey Show, and became Oprah's spiritual advisor.
