Judeans and Jews: four faces of dichotomy in ancient Jewish history

"In writing in English about the classical era, is it more appropriate to refer to 'Jews' or to 'Judeans'? What difference does it make? Today, many scholars consider 'Judeans' the more authentic term, and 'Jews' and 'Judaism' merely anachronisms. In Judeans and Jews, Daniel R. Schwartz argues that we need both terms in order to reflect the dichotomy between the tendencies of those, whether in Judea or in the Disapora, whose identity was based on the state and the land (Judeans), and those whose identity was based on a religion and culture (Jews)"--Front flap.
