Philip the Arab and Christianity that appear—save for one reference to Ishmael—figure in the political history of the first three centuries of the Christian era. To Eusebius, the Saracens of the 4th century are direct-line descendants of the biblical Ishmaelites, descendants of the handmaid, Hagar, and the patriarch, Abraham. They are thus outcasts, beyond God's Covenant with the favored son of Abraham, Isaac.
