ISB ~ Acts 18 v13

contrary to the law:Roman law recognized and protected numerous religions in the empire, including Judaism. The Jews, attempting to discredit the Christian message and disassociate the budding Church from Judaism, accused Paul of promoting a new religion that was neither recognized nor authorized by Rome. Gallio dismissed the charge because he considered the matter an intramural debate among the Jews to be settled in the synagogue (18:15).
