I have read that some Ethiopian Jews cite sefer eldad as a means of proving that they are halachically Jewish, and I want to know how salient of an argument this is. Assuming he was telling the truth, how did so many halochos he implies in the book were accepted get lost? For example, how did a mitzvah as essential as tefilin get discarded by local Jews centuries later? And not only that but given that the book claims that local Jews used Hebrew as their vernacular, how is it possible that the liturgical language for Ethiopian Jews is Geez, the same language used for rites in the Ethiopian Orthodox Church? Also how likely is it that he was telling the truth in the first place?
