Lucretia Mott was the only woman to speak at the organizational meeting in Philadelphia. She tested the language of the society's Constitution and bolstered support when many delegates were precarious. Days after the conclusion of the convention, at the urging of other delegates, Mott and other white and black women founded the Philadelphia Female Anti-Slavery Society. Integrated from its founding, the organization opposed both slavery and racism, and developed close ties to Philadelphia's Black community. Mott herself often preached at Black parishes. Around this time, Mott's sister-in-law, Abigail Lydia Mott, and brother-in-law, Lindley Murray Moore, were helping to found the Rochester Anti-Slavery Society (see Julia Griffiths). Amidst social persecution by abolition opponents and pain from dyspepsia, Mott continued her work for the abolitionist cause. She managed their household budget to extend hospitality to guests, including fugitive slaves, and donated to charities. Mott was praised for her ability to maintain her household while contributing to the cause. In the words of one editor, "She is proof that it is possible for a woman to widen her sphere without deserting it." Mott and other female activists also organized anti-slavery fairs to raise awareness and revenue, providing much of the funding for the movement. Women's participation in the anti-slavery movement threatened societal norms. Many members of the abolitionist movement opposed public activities by women, especially public speaking. At the Congregational Church General Assembly, delegates agreed on a pastoral letter warning women that lecturing directly defied St. Paul's instruction for women to keep quiet in church.(1 Timothy 2:12) Other people opposed women's speaking to mixed crowds of men and women, which they called "promiscuous." Others were uncertain about what was proper, as the rising popularity of the Grimké sisters and other women speakers attracted support for abolition. Mott attended all three national Anti-Slavery Conventions of American Women (1837, 1838, 1839). During the 1838 convention in Philadelphia, a mob destroyed Pennsylvania Hall, a newly opened meeting place built by abolitionists. Mott and the white and black women delegates linked arms to exit the building safely through the crowd. Afterward, the mob targeted her home and Black institutions and neighborhoods in Philadelphia. As a friend redirected the mob, Mott waited in her parlor, willing to face her violent opponents. Mott was involved in a number of anti-slavery organizations, including the Philadelphia Female Anti-Slavery Society, the Pennsylvania Anti-Slavery Society (founded in 1838), the American Free Produce Association,
