It is widely acknowledged that the earliest Christians observed the seventh-day Sabbath in obedience to the Fourth Commandment. What is less often acknowledged is that there have always been Christian communities that continued to honor the seventh-day Sabbath throughout history. One such community is the Seventh Day Baptists, which emerged from the Protestant Reformation. I am excited to be speaking with Nicolas Kersten, the Director of Education and History for the Seventh Day Baptist General Conference, to learn more about this Sabbatarian Christian tradition.
