The Gospel of the Ebionites is one of the Jewish-Christian Gospels, sharing an affinity with the Gospel of the Hebrews and the Gospel of the Nazoraeans. Jerome names it as being the same as the Gospel of the Hebrews and states that most ancient Biblical scholars called it "Matthaei Authenticum" (or the true Gospel of Matthew).  It survives only as fragments in quotations, and so it is difficult to tell if it is an independent text, or whether it is in fact simply a slight variation on the others. It was used by the Ebionite community during the time of the early church.
At the beginning of the Christian era, Jewish Christian communities flourished throughout the Holy Land. The Ebionites were thought to be an offshoot of the Nazarenes. Their center was located east of the Jordan river near where John the Baptist had preached.
The origin of the name Ebionite (or Ebionaean) is debated. Tertullian, Irenaeus, Hippolytus of Rome, Epiphanius of Salamis, and Jerome ascribed the movement to a heretic named Ebion or Hebion. Others claim the name Ebionite means "poor one" and is not derived from a person, but rather the Beatitude from Matthew 5:3. While some note they rejected material wealth, Eusebius and Origen both claimed the Ebionites' appellation was a term of derision indicating a poverty in intellect, rather than material possessions. Conflict grew between them and other Christians when the Ebionites failed to embrace the Church doctrines of chastity or celibacy as well as the concept of the Virgin birth. They believed Jesus was begotten of God at his baptism, see Adoptionism.
Conflict also grew over the issue of the Mosaic law which the Ebionites believed remained in full force, see also Council of Jerusalem. They believed that by fulfilling the law, they are able to become Christs. They are said to have rejected Paul's teachings and used only one Gospel, the Gospel of the Ebionites.  They also have John the Baptist and Jesus being vegetarians, and rendering him in the adoptionist form. Many of these differences are found in subtle variants of Greek words, such as a meal of egkris (cake), rather than akris (locusts) as in the Synoptic Gospels
Epiphanius, whose writing is the main source for finding fragments of the Gospel of the Ebionites, emphasises that the Nazoraeans were considered part of the Christian orthodoxy, whereas the Ebionites were considered heretics, and so there may have been theological and doctrinal differences between the two gospels, possibly over the Virgin Birth which the Ebionites rejected.
Epiphanius considered the Ebionite text to have been mutilated due to textual differences, the lack of a genealogy and nativity story in the Gospel of Matthew - which may indicate that the Ebionites cut it, but may also be a testimony to an earlier, nativity free, version of Matthew, on which the Ebionite Gospel is based.
The Ebionites are said to have used the Gospel of the Hebrews written by the Apostle Matthew. Epiphanius stated that the Ebionites accepted only Matthew's Gospel and they used it alone. They called it the Gospel of the Hebrews, for only Matthew expounded and declared the gospel in Hebrew using Hebrew letters. 
Because of differences in Jesus' baptism account, some modern Biblical scholars have argued that the Gospel of the Hebrews and the Gospel of the Ebionites were two different gospels. However, since only the Gospel of the Hebrews appears in Early Christian catalogues and because Jerome links the Ebionites with the Nazarenes in their use of the Gospel of the Hebrews, this contention is rendered doubtful. 
Finally, Legrange has argued that Matthew's Gospel of the Hebrews, used by the Ebionite community was actually "Aram M".  For further discussion of Aram M see the Two-source hypothesis and the Four Document Hypothesis.
|The Gospel of the Ebionites|
|The Gospel of the Ebionites is a lost text. A few fragments survive in the form of quotations from the Church Father Epiphanius.|
It came to pass in the days of Herod, King of Judaea under the high priest Caiaphas, that John came and baptized with the baptism of repentance in the river Jordan; he is said to be from the tribe of Aaron and a son of Zacharias the priest and of Elizabeth and all went out to him.
And it came to pass when John baptized, that the Pharisees came to him and were baptized, and all Jerusalem also. He had a garment of camels' hair, and a leathern girdle about his loins. And his meat was wild honey, which tasted like manna, formed like cakes of oil.
The people having been baptized, Jesus came also, and was baptized by John. And as he came out of the water the heavens opened, and he saw the Holy Spirit descending under the form of a dove, and entering into him. And a voice was heard from heaven: "Thou art my beloved Son, and in thee am I well pleased. And again: "This day have I begotten thee." And suddenly shone a great light in that place. And John seeing him, said, "Who art thou, Lord?" Then a voice was heard from heaven: "This is my beloved Son, in whom I am well pleased." Thereat John fell at his feet and said: "I pray thee, Lord, baptize me." But he would not, saying "Suffer it, for so it behoveth that all should be accomplished."
[Matthew said] "And there was a man named Jesus, and he was about thirty years old; he has chosen us. And He came into Capernaum and entered into the house of Simon, surnamed Peter, and He opened His mouth and said, 'As I walked by the sea of Tiberias, I chose John and James, the sons of Zebedee, and Simon and Andrew and Thaddaeus and Simon Zelotes, and Judas Isariot; thee also, Matthew, when thou wast sitting at the receipt of custom, did I call and thou didst follow me. According to my intention ye shall be twelve apostles for a testimony unto Israel.'"
[Jesus was told] "Behold thy mother and thy brethren stand without."
[He said] "Who is my mother and who are my brethren?" And He stretched forth His hand toward His disciples and said: "These are my brethren and my mother and sisters, which do the will of my Father."
[Jesus said] "I am come to abolish the sacrifices: if ye cease not from sacrificing, the wrath (of God) will not cease from weighing upon you."
[The disiples said,] "Where wilt Thou that we prepare for Thee to eat the Passover?" To which He replied: "I have no desire to eat the flesh of this Paschal Lamb with you."
