Mike Rinder, best known as the co-host of the Emmy-winning A&E series Leah Remini: Scientology and the Aftermath, has passed away at the age of 69. His death was confirmed by his wife, Christie King Collbran, on January 5, 2025, through an emotional Instagram post. While the cause of death was not immediately revealed, Rinder had been diagnosed with advanced esophageal cancer in June 2023.

Rinder’s death marks the end of a remarkable and tumultuous journey, one that saw him evolve from a key figure within the Church of Scientology to one of its most prominent whistleblowers. In his later years, Rinder was beloved by many for his courage in speaking out against the church’s practices and for his work on Leah Remini: Scientology and the Aftermath, a show that shed light on the abuses and harassment allegedly perpetrated by the organization.

A Life of Courage and Advocacy

In her Instagram tribute, Christie King Collbran shared heartfelt words about her late husband, describing him as “my sweet, beautiful husband” and expressing the profound grief felt by their family. “Rest in peace… Your courage, bravery, and integrity are unmatched and will forever inspire us,” she wrote. She also emphasized Rinder’s role as a pillar of strength in their lives, noting his ability to bring wisdom, love, and laughter to those around him.

She added, “The world will remember you. My best friend, my hero, my love, Michael John Rinder.”

Along with her tribute, Collbran shared Rinder’s final wishes, revealing a deeply personal message from her husband. Rinder had requested that his blog site, which contains over 4,000 posts and 300,000 comments, be preserved as an archive of his thoughts and work. His blog had become an essential platform for exposing the inner workings of Scientology, especially its abuse and disconnection policies.

Rinder’s Final Words

Rinder’s last words, shared posthumously by Collbran, offer a glimpse into the man he was and the legacy he leaves behind. “If you are reading this, I have shuffled off this mortal coil in accordance with the immutable law that there are only two certainties in life: death and taxes,” he wrote with his characteristic dry humor.

He also reflected on the life he had lived: “I have been lucky — living two lives in one lifetime. The second one, the most wonderful years anyone could wish for, with all of you and my new family!”

One of Rinder’s only regrets, he shared, was not fully achieving his goal of ending the abuses within Scientology, particularly the controversial practice of “disconnection.” Disconnection involves the practice of severing all ties with individuals deemed enemies of the church, including family members. This policy had been a focal point of Rinder’s advocacy, and he encouraged those still fighting to end it to “keep the flag flying” and “never give up.”

Rinder’s message also included a personal request for those who wished to send flowers to instead contribute to the college fund of his son, Jack. “Let the flowers grow and look to the future,” he wrote, a reflection of his optimistic outlook despite the hardships he faced.

A Remarkable Career and Legacy

Mike Rinder was born into the Church of Scientology, raised within its ranks, and held several high-ranking positions, including international spokesperson, head of the Office of Special Affairs, and a member of the Board of Directors of the Church of Scientology International. In 2007, after more than 40 years within the organization, he made the brave decision to leave Scientology and became one of its most vocal critics.

Rinder’s defection from the church and his subsequent whistleblowing efforts were pivotal in bringing attention to Scientology’s alleged abuses. His appearances in the 2015 HBO documentary Going Clear: Scientology and the Prison of Belief were critical in raising public awareness about the church’s controversial practices.

However, it was his role as co-host of Leah Remini: Scientology and the Aftermath that truly solidified his place in the hearts of many. The series, which aired for three seasons, provided a platform for former Scientologists to share their stories and exposed the psychological, emotional, and financial toll the church had taken on its followers. Rinder’s participation in the series, where he offered insight into the inner workings of Scientology, was invaluable in documenting the church’s alleged abuses.

Public Tributes and Support

Following the announcement of Rinder’s death, tributes poured in from across the world, especially from those who admired his bravery and commitment to justice. Many took to social media to express their sorrow, highlighting Rinder’s role as a hero for those who had been silenced by the church.

One fan shared, “He seemed like a wonderful, smart, funny, kind man. I’m so sorry for your loss. He enlightened so many.”

Another wrote, “A true hero with a heart of gold. What a brave and courageous man to stand and fight for what he believes. I loved watching Mike and @leahremini fight for those that need a voice. I’m so sorry for your loss. Prayers to all of you. God bless.”

Fans and supporters echoed similar sentiments, with many expressing gratitude for Rinder’s work in shedding light on the truth about Scientology, and for his continued fight for those who had been harmed by the church.

A Final Chapter of Advocacy

Mike Rinder’s death marks the end of an era for many who looked up to him as a voice of reason and strength. His advocacy, both in his personal life and on the public stage, will continue to resonate for years to come.

In her post, Christie Collbran honored the legacy Rinder leaves behind, calling him not only her best friend but also a “hero” and a source of “strength” for their family. The world may have lost a powerful advocate for truth, but his message will live on. As Rinder requested, “The life of the dead is placed in the memory of the living,” and his memory will undoubtedly continue to inspire others to fight for justice, to question authority, and to seek the truth at all costs.

Rest in peace, Mike Rinder.
