Baptist minister who wrote An Appeal to the Public for Religious Liberty in 1773, making the case that taxing citizens to support an established church was a violation of conscience. He brought the Baptist argument directly to the Continental Congress.

A Standing Rock Sioux scholar and activist whose book God Is Red (1973) argued that Indigenous spiritual traditions deserved the same protections as any other faith in America. He contended that religious freedom means little unless it extends to Indigenous communities whose traditions the state had long tried to erase.

German pastor whose work The Cost of Discipleship (1937) argued that the church owes its allegiance to God alone, not to any government. He was executed by the Nazis in 1945 for his resistance.

An American theologian whose book The Children of Light and the Children of Darkness (1944) argued that democracy requires humility — that no person, party, or faith tradition is righteous enough to rule without accountability.

A Texas Baptist pastor who, in 1920, stood on the steps of the U.S. Capitol and delivered what became the defining Baptist argument for the separation of church and state. He declared that religious freedom is the gift of God, not the state — and that no government has the authority to compel or restrict the conscience.

An indentured servant born to free Black parents in Connecticut in 1803, she became a prolific activist and delivered powerful public speeches — something unthinkable for a Black woman at the time. She spoke about religion, women’s rights, abolition, and prejudice.

A Polish-born rabbi and theologian who became one of the most important religious voices in 20th century America. He marched alongside Martin Luther King Jr. at Selma, famously saying he felt as though his legs were praying. Heschel argued that indifference to the suffering of others is a sin against God — and that religious freedom is inseparable from human dignity.

A Baptist minister who became the moral conscience of America. Drawing on Scripture, Baptist theology, and the Declaration of Independence, he argued that segregation was a violation of the God-given dignity of every person. His campaigns in Birmingham and Selma demonstrated that faith is not a private matter — it is a public obligation.
