A Messianic Shabbat service can be intimidating to the newcomer. The order of service may be unfamiliar, but it is rooted in the Jewish and First Century traditions of Yeshua and his disciples. This booklet gives a brief history of the Nazarene Jews and describes the present-day return to many First Century beliefs and observances. It also describes the diversity of the worship practices that a newcomer or visitor may encounter in a Messianic Shabbat Service. More importantly, it gives the rationale or Scriptural basis for those practices so that the participant may understand the service and leave it feeling encouraged in his or her faith.
