When Ardeth Platte was released in 2005 after more than two years in federal prison in Danbury, Conn., she made a confession. Smiling, her eyes crinkling, she admitted to me that the nice soft sheets on the beds on the outside felt truly wonderful.

The then-69-year-old Dominican nun was happy to be free, but wholly unrepentant. As Sen. Dianne Feinstein might say, the dogma lived loudly within her, and if going to prison periodically was the price of living her faith, so be it.

CLEVELAND — Dominican Sister Ardeth Platte long considered herself a peacemaker and devoted nearly 40 years of her life to praying and witnessing to end war and rid the world of nuclear weapons.

Her actions led to imprisonment multiple times, including for the 2002 defacement of a missile silo in Colorado in collaboration with her best friend, Dominican Sister Carol Gilbert, and fellow Dominican Sister Jackie Hudson.

Platte, 84, died in her sleep at the Dorothy Day Catholic Worker House in Washington early Sept. 30. Funeral arrangements were pending Oct. 5 because of the coronavirus pandemic.

Like many Catholics, the nuns were compelled to activism by Vatican II, the early-1960s church council that encouraged its members to be more engaged with the world.

By the early ’80s, inspired by the Australian doctor and antinuclear activist Helen Caldicott, they turned their focus to the nuclear weapons and bombers located in bases in their home state. For more than a decade, through hundreds of protests, legal challenges and sheer doggedness, they were among those who were instrumental in Michigan’s decision to close its nuclear bases in 1995.

“Ardeth was very keen on the law,” Anabel Dwyer, a Michigan-based lawyer who worked for decades on the nuns’ behalf, said in a phone interview. “She stood for the Nuremberg principles, the universal prohibitions against war crimes. Her resistance was based on the fact that nuclear weapons unleash uncontrollable and indiscriminate heat, blast and radiation and thus violate intransgressible rules of law.

“Obviously it was a moral question for her as well,” Ms. Dwyer continued, “but when she was in court she wanted to argue in terms of the law itself. She had a real instinct for justice on a large scale, for democracy as an act.”
