George drafted the "", a manifesto signed by Orthodox, Catholic and Evangelical leaders that "promised resistance to the point of civil disobedience against any legislation that might implicate their churches or charities in abortion, embryo-destructive research or same-sex marriage." He has also joined with Muslim scholar Shaykh Hamza Yusuf in urging hotel chains and other businesses to refrain from offering or promoting pornography. He has worked closely with his former student Rabbi Meir Soloveichik and with Rabbi Lord Jonathan Sacks of Great Britain to combat anti-Semitism in Europe. Along with other public intellectuals, George played a key role in creating the "theoconservative" movement and integrating it into mainstream Republicanism. Much of George's work on religious liberty has centered on the idea that religion is a "distinct human good", which he asserts allows people to "live authentically by ordering one's life in line with one's best judgments of conscience."
