I want to reinforce how BAD Epiphanius's reporting on the Ebionites really is. He starts with the seven sects of Judaism as he calls them. Then he makes mention of a certain Elxai - the alleged (and surely fictitious) founder of the 'Elxasites' i.e. those of the 'hidden God.' Since he knows of Irenaeus's report he just ASSUMES that Elxai was once an Ebionite but has no actual proof:
And I shall pass this sect by as well. For again, Elxai is associated with the Ebionites after Christ, as well as with the Nazoraeans, who came later. (5) And four sects have made use of him because they were bewitched by his imposture: Of those < that came > after him, < the > Ebionites < and > Nazoraeans; of those before his time and during it the Ossaeans, and the Nasaraeans whom I mentioned earlier
So the relationship between 'Elxai' - a wholly fictitious 'founder of a sect' (much like 'Ebion') - and the Ebionites is essentially made up owing to an attempt to reconcile his source on the Elxasites and Irenaeus's reporting on the Ebionites. Similarity he just ASSUMES that the Ebionites were somehow related to the'Ossaeeans' and the 'Sampsites' (the sun-worshipers) but again no actual proof:
At all events, these were the seven sects in Israel, in Jerusalem and Judaea, and the four I mentioned in “Samaritans” in Samaria. But most of them have been eliminated. There are no Scribes any longer, no Pharisees, Sadducees, Hemerobaptists or Herodians. (2) There are only a handful of Nasarenes, perhaps one or two, above the Upper Thebaid and beyond Arabia; and the remnant of Ossaeans, no longer practicing Judaism but joined with the Sampsites, who in their turn < live > in the < territory > beyond the Dead Sea. Now, however, they have been united with the sect of the Ebionites. (3) And as a result they have lapsed from Judaism—as though a snake’s tail or body had been cut off and a snake with two heads and no tail had sprouted from it, grown on and attached to a body chopped in half.
In other words, Epiphanius's 'knowledge' comes down to nothing more than holding one book in one hand and another book (Irenaeus) in the other and reconciling the two written reports with one another WITH NO OBVIOUS JUSTIFICATION OTHER THAN A NEED TO COMPLETE HIS PANARION. So again later:
Ebionites are very like these Cerinthians and the Nazoraeans; and the sect of the Sampsaeans and Elkasaites was associated with them to a degree = first part based on proximity in Irenaeus
The Nazoraeans are another example of 'one book in one hand' another book in another hand and a willingness to reconcile:
On the Nazoraeans: For they acknowledge both the resurrection of the dead and that all things have been created by God,35 and they declare that God is one, and that his Son is Jesus Christ. = This is said of the Ebionites at Iren. 1.26.2. Cf. Hipp. Refut. 7.34.1; PsT 3.
On the Nazoraeans - They disagree with Jews because of their belief in Christ; but they are not in accord with Christians because they are still
fettered by the Law—circumcision, the Sabbath, and the rest.36 (6) As to Christ, I cannot say whether they too are misled by the wickedness of Cerinthus and Merinthus, and regard him as a mere man—or whether, as the truth is, they affi rm that he was born of Mary by the Holy Spirit. = Cf. Iren. 1.26.2 (of the Ebionites); Eus. H. E. 3,27.3. The whole section here shows signs that Epiphanius is reading from the section on the Ebionites while explaining the Nazoraeans.
On the Nazoraeans - They have the Gospel according to Matthew in its entirety in Hebrew.48 For it is clear that they still preserve this as it was originally written, in the Hebrew alphabet. But I do not know whether they have also excised the genealogies from Abraham till Christ. = section drawn from Irenaeus
All of this is just reconciling (a) a report on the Nazoraeans with (b) Irenaeus's reporting on the Ebionites. This continues through the first lines of his account on the Ebionites:
On the Ebionites - Following these and holding views like theirs, Ebion,2 the founder of the Ebionites, arose in the world in his turn as a monstrosity with many forms, and practically represented in himself the snake-like form of the mythical many-headed hydra. He was of the Nazoraeans’ school, but preached and taught other things than they = Epiphanius making Irenaeus's account of the Ebionites fit with a presumption that the first Jewish Christians were called Nazoraeans.
For it was as though someone were to collect a set of jewelry from various precious stones and an outfit of varicolored clothing and tog himself up conspicuously. Ebion, in reverse, took any and every doctrine which was dreadful, lethal, disgusting, ugly and unconvincing, thoroughly contentious, from every sect, and patterned himself after them all. (3) For he has the Samaritans’ unpleasantness but the Jews’ name, the opinion of the Ossaeans, Nazoraeans and Nasaraeans, the form of the Cerinthians, and the perversity of the Carpocratians. And he wants to have just the
Christians’ title—most certainly not their behavior, opinion and knowledge, and the consensus as to faith of the Gospels and Apostles! 1,4 But since he is midway between all the sects, as one might say, he amounts to nothing. The words of scripture, “I was almost in all evil, in the
midst of the church and synagogue,”3 are applicable to him. (5) For although he is Samaritan, he rejects the name because of its objectionability. And while professing himself a Jew, he is the opposite of the Jews—though he does agree with them in part as I shall prove later with God’s help, through the proofs of it in my rebuttal of them = this is just a reflection of Epiphanius's own making sense of how Irenaeus's Ebionites fit in the middle of the various other names and reporting Epiphanius has uncovered
For this Ebion was contemporary with the Jews, and < since he was > with them, he was derived from them.= Epiphanius has Hippolytus's story about Ebion the founder of the Ebionites or some such text
The 'made up history' culminates in a claim that these sects had a common point of origin:
Their origin came after the fall of Jerusalem. For since practically all who had come to faith in Christ had settled in Peraea then, in Pella, a town in the “Decapolis”10 the Gospel mentions, which is near Batanaea and Bashanitis—as they had moved there then and were living there, this provided an opportunity for Ebion. (8) And as far as I know, he first lived in a village called Cocabe in the district of Qarnaim—also called Ashtaroth—in Bashanitis. There he began his evil teaching—the place, if you please, where the Nazoraeans I have spoken of came from. (9) For since Ebion was connected with them and they with him, each party shared its own wickedness with the other. Each also differed from the other to some extent, but they emulated each other in malice. But I have already spoken at length, both in other works and in the other Sects, about the locations of Cocabe and Arabia
This is a total laughable 'history' which just tells us that there were a lot of 'Jewish Christians' in this region - whatever that means, and whatever characteristic these men had. Epiphanius's actual 'history' is nonsensical and useless. And notice that what Epiphanius goes on to contribute is the idea that a 'Jewish Christian element' lived in Palestine - not that Irenaeus's reporting about the Ebionites is confirmed in any way. Listen to how general and vague his account becomes of this 'mishmash' Jewish Christian community in what follows:
And at first, as I said, Ebion declared that Christ is the offspring of a man, that is, of Joseph. For a while now, however, various of his followers have been giving conflicting accounts of Christ, as though they have decided on something untenable and impossible themselves. (2) But I think it may be since they were joined by Elxai—the false prophet < I mentioned earlier > in the tracts called “Sampsaeans,” “Ossenes” and “Elkasaites”—that they tell an imaginary story about Christ and the Holy Spirit as he did. 3,311 For some of them even say that Adam is Christ—the man who was formed first and infused with God’s breath.12 (4) But others among them say that he is from above; created before all things, a spirit, both higher than the angels and Lord of all; and that he is called Christ, the heir of the world there.13 But he comes here when he chooses,14 as he came in Adam and appeared to the patriarchs clothed with Adam’s body. And in the last days the same Christ who had come to Abraham, Isaac and Jacob, came and donned Adam’s body, and appeared to men, was crucified, rose and ascended. (6) But again, when they choose to, they say, “No! The Spirit—that is, the Christ—came to him and put on the man called Jesus.”15 And they get all giddy from making different suppositions about
him at different times. 3,7 They too accept the Gospel according to Matthew. Like the Cerinthians and Merinthians, they too use it alone. They call it, “According to the Hebrews,” and it is true to say that only Matthew expounded and preached the Gospel in the Hebrew language and alphabet16 in the New Testament. 3,8 But some may already have replied that the Gospel of John too, translated from Greek to Hebrew, is in the Jewish treasuries ...
The story that follows has no value either. It just tells us that 'Jewish Christian' sectarians or in point of fact a variant Christianity which outwardly seemed more 'Jewish' was existing in Palestine. But how any of this proves that an 'Ebionite sect' ever existed or what it meant or what it was like is absolutely ridiculous.
It is utterly laughable to take Epiphanius's reporting seriously. He's just piecing together wholly separate things and making a false narrative.
