The reasons for the decline of Hellenistic Judaism are obscure. It may be that it was marginalized by, absorbed into, or became Early Christianity (see the Gospel according to the Hebrews). The Epistles of Paul and the Acts of the Apostles report that, after his initial focus on the conversion of Hellenized Jews across Anatolia, Macedonia, Thrace and Northern Syria without criticizing their laws and traditions, Paul the Apostle eventually preferred to evangelize communities of Greek and Macedonian proselytes and Godfearers, or Greek circles sympathetic to Judaism: the Apostolic Decree allowing converts to forego circumcision made Christianity a more attractive option for interested pagans than Rabbinic Judaism, which required ritual circumcision for converts (see Brit milah).
