The Mapping the Doctrine of Discovery podcast, hosted by Philip P. Arnold and Sandy Bigtree (Mohawk Nation), critically examines the historical and ongoing impacts of the Doctrine of Christian Discovery. Rooted in 15th-century papal edicts, this doctrine provided theological and legal justification for European colonialism, the seizure of Indigenous lands, and the subjugation of non-Christian peoples. The podcast explores how these principles became codified in U.S. law, from Johnson v. M’Intosh (1823) to Sherrill v. Oneida (2005), and continue to underpin contemporary legal, religious, and corporate frameworks. Featuring discussions with scholars, legal experts, and Indigenous leaders, the series sheds light on how this doctrine fuels environmental destruction, economic exploitation, and cultural genocide while also highlighting Indigenous resistance and calls for justice, land restoration, and the repudiation of these colonial structures.
