Trinity Presbyterian Church recognizes that we live on unceded land that was faithfully stewarded and kept by Indigenous Peoples for countless generations. The land in the Bay Area that touches our feet was once populated by the Chochenyo, Ramaytush, Muwekma and Bay Miwok Peoples. We acknowledge that the land was taken from these First Nation Peoples with violence and without treaty. We recognize the Ohlone Peoples survived over two centuries of genocide, enslavement and colonization and that this was often done under the cover of Christianity and the Doctrine of Discovery; we lament this misuse of our religion to oppress and kill. We pay our respects to the Indigenous Elders, past, present and future. We honor their ongoing work aimed at recognition and their fight to recover that relationship with the land we are privileged to walk upon.
