The Ebionites were a sect of Jewish Christians in the early centuries of Christianity. Little is known about them, and it appears that most or all of their texts were destroyed or lost, possibly as a result of efforts by the proto-Orthodox faction to marginalize and eliminate their movement.
The vast majority of what we do know about them is based on the extremely biased accounts of proto-Orthodox Christians, who labeled the Ebionites as heretics and were inclined to paint a very bleak picture of the sect. These sources are dubious at best, and can only tell us what outsiders thought about the Ebionites; they are of little or no use in trying to discover what the Ebionites themselves believed, how they worshipped, and what their religion stood for.
Do we have any accounts of the Ebionites from sources less biased than the church fathers?
