Atheist Bible Study 1: Genesis

[Bucky Ball]

As late as the late 300's AD, the split between Judaism and Christians was still not complete.

"Adversus Judaeos (Greek Kata Ioudaiōn, "against the Jews" or "against the Judeans") are a series of fourth century homilies by John Chrysostom directed to members of the church of Antioch of his time, who continued to observe Jewish feasts and fasts. Critical of this, he cast Judaism and the synagogues in his city in a critical and negative light."

When he was made Bishop of Constantinople, they also were found to be doing the same things ... and he railed against it again in he Christmas sermon, of the year 400.

"Homilies against Jews and Judaizing Christians[edit]

Main article: Adversus Judaeos

During his first two years as a presbyter in Antioch (386–387), John denounced Jews and Judaizing Christians in a series of eight homilies delivered to Christians in his congregation who were taking part in Jewish festivals and other Jewish observances.[44] It is disputed whether the main target were specifically Judaizers or Jews in general. His homilies were expressed in the conventional manner, utilizing the uncompromising rhetorical form known as the psogos (Greek: blame, censure).[citation needed]

One of the purposes of these homilies was to prevent Christians from participating in Jewish customs, and thus prevent the perceived erosion of Chrysostom's flock. In his homilies, John criticized those "Judaizing Christians", who were participating in Jewish festivals and taking part in other Jewish observances, such as the shabbat, submitted to circumcision and made pilgrimage to Jewish holy places.[45]

John claimed that synagogues were full of Christians, especially Christian women, on the shabbats and Jewish festivals, because they loved the solemnity of the Jewish liturgy and enjoyed listening to the shofar on Rosh Hashanah, and applauded famous preachers in accordance with the contemporary custom.[46] A more recent theory is that he instead tried to persuade Jewish Christians, who for centuries had kept connections with Jews and Judaism, to choose between Judaism and Christianity.[47]

In Greek the homilies are called Kata Ioudaiōn (Κατὰ Ιουδαίων), which is translated as Adversus Judaeos in Latin and Against the Jews in English.[48] The original Benedictine editor of the homilies, Bernard de Montfaucon, gives the following footnote to the title: "A discourse against the Jews; but it was delivered against those who were Judaizing and keeping the fasts with them [the Jews]."[48]

According to Patristics scholars, opposition to any particular view during the late 4th century was conventionally expressed in a manner, utilizing the rhetorical form known as the psogos, whose literary conventions were to vilify opponents in an uncompromising manner; thus, it has been argued that to call Chrysostom an "anti-Semite" is to employ anachronistic terminology in a way incongruous with historical context and record.[49] This does not preclude assertions that Chrysostom's theology was a form of Anti-Jewish supersessionism.[50]
