An Old Testament Practice or a Later Return to It

Historians disagree about how the double Sabbath actually began, and the disagreement matters because the two answers tell very different stories about the tradition itself. One reading holds the practice descends directly from a documented ancient link between the kingdom of Aksum and the wider Jewish and Israelite world, the same link the church's own Kebra Nagast narrative places at the founding of its royal line; on this reading Saturday observance is one surviving strand of a Judaic layer within Ethiopian Christianity older than the church's own conversion. A second reading treats the practice as a later development, part of a broader wave of scripturally minded reform inside the Ethiopian church centuries after Christianity's initial arrival, when biblical precedent rather than continuous unbroken custom drove new observances into practice. Edward Ullendorff's own scholarly assessment of the Ark and tabot tradition the church connects to this history takes the second, more skeptical position seriously without dismissing the tradition's own account outright, treating the evidence as genuinely unsettled rather than as a case already closed in either direction. The double Sabbath itself is not in question; only how far back its Israelite framing actually reaches is.
