I would be extremely interested in this question as well. In the fifteenth and sixteenth centuries Iberian missionaries were distressed about the observance of the Saturday sabbath in the Orthodox Ethiopian church. It was among the Judaizing heresies they railed against. I was not aware, however, that Saturday observance had come up much earlier in Raymond de Penaforte’s Summa, well before Ethiopians and Europeans had much contact. Of course, there had long been an important Ethiopian presence in Jerusalem.
