In Christian tradition, Baptism is considered a once in a lifetime event, symbolising conversion and spiritual death, burial and resurrection with Christ. Although it is a New Testament command, not all groups practice Baptism.
In the Jewish and Messianic traditions, there are multiple baptisms, or ‘Mikveh’.
The Jewish Mikveh was required by Torah as a ritual cleansing – monthly for women after her monthly period, and after childbirth, and for men after uncleanness of any kind including after healing from sickness.
In the Messianic traditions, in addition to the ‘Messianic Mikveh’ in common with Christianity, believers may also comply with the ritual Mikveh cleansings as a symbolic reminder for the ongoing need for holiness.
