Ewostatewos

Ewostatewos (1273–1352) was an Ethiopian Orthodox monk and religious leader born near Mekelle in Enderta. Educated by his uncle Abba Daniel, he founded a monastery in Serae, where he taught that Christians should keep both Saturday, the Old Testament Sabbath, and Sunday as days of rest.

When Abuna Yaqob rejected his teaching around 1337, Ewostatewos went into exile with his disciples, travelling through Sudan and Cairo, where he defended his views before the Coptic patriarch, and then Jerusalem. He died in Cilician Armenia in 1352, and his disciples, the Ewostathians, spread his Sabbath teaching across Ethiopia.
