A Festschrift, compiled by Zeba Crook and Philip Harland, was made in honor of Stephen G. Wilson, who was

Professor of Religion at Carleton University,Ottawa, and Director of the College of Humanities until his retirement in 2007. His contributions to the study of the religious identities of Jews, Christians, and Gentiles in the first three centuries of the Common Era are widely acknowledged; his interests have been no less in the contrasting and sometimes conflicting religious identities within each of these three groups. Among his best-known publications are The Gentiles and the Gentile Mission in Luke–Acts (1973), Luke and the Law (1983), Related Strangers: Jews and Christians 70–170 CE (1995), and Leaving the Fold: Defectors and Apostates in Antiquity (2004).

A review of the work by Thomas W. Gillespie gives a synopsis for each of the articles included. There were two that I found particularly interesting:

John Barclay, using theories of ethnicity, argues from Josephus’s Against Apion that the meaning of Ιoυδαιoς is best understood as an ethnic reference to descent, history, territory, and language as well as religion and should be translated “Judean” rather than “Jew.” John Kloppenborg seeks the identity of the fictive author of the letter of James, and thus also that of the equally fictive “Diaspora” (Jas 1:1) to whom it was addressed, and argues that they were probably Jewish-Christians or possibly “Judeans of the diaspora.”
