The Doctrine of Discovery: When Might Claimed to Be Right

Two people hold an old colonial map of the Americas. A healing glow comes from the hands as the people speak to each other.

For most of human history, conflicts have been settled by conquest. The Doctrine of Discovery gave that old pattern a sacred seal. Rooted in fifteenth-century papal bulls, it held that Christian rulers could claim lands and peoples not already under Christian rule. It later entered U.S. law through Johnson v. M’Intosh (1823) and is still cited in courts today.

Both the Unitarian Universalist Association and the Vatican have repudiated the doctrine, yet its legacy shapes land title, treaty rights, and the question of how nations justify taking territory. This service looks at where the doctrine came from, why it endured even after its religious source was disowned, and what a faith committed to the inherent worth and dignity of every person might do in response.
