The Dominican Sisters of Hawthorne, operators of Rosary Hill Home in New York, have filed a federal lawsuit against state officials, challenging a 2023 gender-identity mandate that would force them to use preferred pronouns, assign rooms based on gender identity, and post anti-discrimination notices. The sisters, who have served terminal cancer patients for 125 years, argue the law violates their First Amendment rights to free speech and free exercise of religion. Their superior, Mother Marie Edward, states compliance would force them to act against Catholic teaching on the immutability of sex and the truth of Christ. The lawsuit, however, is framed entirely within the U.S. constitutional system of “religious freedom,” a concept condemned by pre-1958 Catholic doctrine, and is pursued while the congregation remains in formal communion with the post-conciliar hierarchy, whose members are, by sedevacantist theology, manifest heretics who have lost office. This legal strategy, therefore, represents not a defense of the Faith but a tragic manifestation of the very Modernism and secularist compromise that has hollowed out the Church since 1958.
