Informed by the postsecular notion that religious and secular actors should recognize their mutual relevance in contemporary society, Dillon examines how secular realities and church doctrine intersect in American Catholicism. She shows that the Church's 21st-century commitment to institutional renewal has been amplified by Pope Francis's vision of public Catholicism and his accessible language and intellectual humility. Combining wide-ranging survey data with a rigorous examination of Francis's statements on economic inequality, climate change, LGBT rights, and women's ordination, the highly consequential Vatican Synod on the Family, and the US Bishops' religious freedom campaign, Postsecular Catholicism assesses the initiatives and strategies impacting the Church's relevance in the contemporary world.
