Jews are called (not demanded) to continue to live and identify themselves as Jews, but we in no way feel it is right to compel Gentile believers to honor the liturgical aspects ( i.e. Circumcision, Saturday Sabbath, food laws, feasts) to be saved. I find it fascinating that one of the first proponents of one of the most damaging, murderous theologies ever to be stated, Replacement Theology, was also a proponent of Messianic Judaism!
