Jung Mo Sung (born 1957) is a Roman Catholic lay theologian, writer and lecturer trained in theology, ethics, and education.
Though he may be viewed as rejecting the idea that some sort of historical subject, whether God, the proletariat, or even a particular set of social institutions, will bring into history the utopian dream of a truly just, peaceful, and harmonious society, he is not passive in the face of injustice.
Sung is currently a professor in the graduate program of religious studies at the Methodist University of São Paulo, where he has been teaching since 1994.
He has served as an informal associate of the "Departamento Ecuménico de Investigaciones," a research institute in Costa Rica founded by Franz Hinkelammert, Hugo Assmann and Pablo Richard Guzmán.
The publication of Desire, Market and Religion in 2007 brought Sung's work into English as the sole author of a book-length project for the first time.
