I saw this in their front page.
"YHWH is Our God, YHWH Alone. "
I think it shows their mentality.
If one’s mind is filled by something, s/he doesn’t see anything else, naturally, and thus don’t even think of other possibilities.
So, in their minds, there are other Gods and they are busy trying to overrate a God among many as a single possibility (in this case other GODs, for example).
They don’t know, but they are lying to themselves (or they are self-contradicting if someone prefers), by their very claim of monotheistic belief because they are peeking at other Gods and they don’t even fully worship/concentrate on their God.
So, I think it’s just another one of silly religions, a system to deceive oneself so that one can think s/he relates/belongs to something Absolute/Infinite.
In their FAQ:
[i]What is the goal of the Ebionites?
We have several related goals:
* The promotion of monotheistic Yahwism (Judaism).
* The promotion of this to gentiles
* The restoration of the good name of Yahshua ben Yosef as a righteous Jew
* This necessitates the deconstruction of the mythological "Jesus" of Christianity, disproving that Christianity is a biblically related religion.
* Social justice based on honesty, and love in the context of the Bible (Tanak).

Well, the base of their belief about the monotheistic nature of their local God isn’t so honest.
Yet they want to control others (indicated by the desire for “social justice”) based on “honesty”.
Overrating maniacs like many of monotheists would never be totally “honest” (nor rational) as long as they cling to their religion.
So, it’s just one of many monotheistic sect among many, to me.
