Carol Rose

Carol Rose is a pastor, sometimes a poet, always one to delight in earth. This former director of CPT is a longtime worker for a just peace that dismantles colonialism inside of us and in the structures that hold it in place. Carol is a member of the Dismantling the Doctrine of Discovery Coalition and leader of the Coalition’s Protect Oak Flat Campaign that follows the lead of the Apache Stronghold. She lives on Tohono O’odham land in the verdant Sonoran desert city of Tucson, Arizona. Carol is happy to lead anywhere online. In defense of the earth, she seeks to abstain from flying for presentations and events.

Themes for presentations: 

  • Protect Oak Flat: Following Apache lead with prayer at the center of the movement does more than protect one small area of sacred land in land claimed by Arizona. It shifts the center, has potential to change laws that disregard indigenous spiritualities and land, and might just decolonize us, too!
  • Dismantling the Doctrine of Discovery – Dismantling the Climate Crisis: The same structures that dispossess and oppress Indigenous Peoples have also created the climate crisis. The thinking and structures that got us into these messes will not get us out. Let’s follow indigenous leadership for a change!

John Stoesz

John Stoesz spent 30+ years working in leadership roles for faith-based justice and peace organizations. These include the Dallas Peace Center, Greater Dallas Community of Churches, Metropolitan Christian Council of Philadelphia, and Mennonite Central Committee Central States. He now devotes his time to two passions: riding his recumbent tricycle and Indigenous justice. In 2012 his family sold his grandparents’ farm in southwestern Minnesota. Since this is Dakota homeland, he donated half the sale amount from his portion to Native organizations working for land justice — most to Makoce Ikikcupi (Land Recovery in the Dakota language). In 2013 he pedaled his trike 2,000 miles through 40 Minnesota counties to raise awareness. He continues to spend significant time on awareness raising, fundraising and organizing among white people, mostly in Minnesota and Kansas, for Native land return.

Themes for presentations: 

  • The Family Farm and Native Land Return: a personal story
  • The Doctrine of Discovery and the History of “Legalized” Land Theft
  • Undoing the Doctrine of Discovery: Demystifying a Mysterious Concept
