Building on the research done by E. J. Epp, B. D. Ehrman situates the origin of the ancestor of the text of Codex Bezae in an anti-Semitic milieu, which would explain the anti-Judaic tendencies of that text. This localisation of the ideological discourse in a specific milieu characterized by a negative stance toward the Jewish people on ethnic grounds seems to rest on the assumption that the text was produced by a non-Jewish Christian. The goal of the present contribution is to test this assumption as it relates to the text of the Acts of the Apostles in the Codex Bezae. With the aid of the concept of ethnicity, and especially the idea of common ancestry, we aim to discover how this text, compared to the text of Codex Vaticanus, depicts the relation of ethnic identity with the Jewish people. Contrary to what might be expected from Ehrman's suggestion, the text of Acts in Codex Bezae emphasizes the indicators of Jewish ethnic identity.
