Ebion is identified with a follower of Cerinthus, just as Matthew follows Mark. Matthew is a Cerinthus's Gospel that has been Ebionitized.
Not coincidentially, the ebionites used Matthew, while Mark is connected with the Cerinthians.
Those, again, who separate Jesus from Christ, alleging that Christ remained impassible, but that it was Jesus who suffered, preferring the Gospel by Mark, if they read it with a love of truth, may have their errors rectified.

Irenaeus,
Haer. 1.26.2:
Those who are called Ebionites agree that the world was made by God; but their opinions with respect to the Lord are similar to those of Cerinthus and Carpocrates. They use the Gospel according to Matthew only, and repudiate the Apostle Paul, maintaining that he was an apostate from the law. As to the prophetical writings, they endeavour to expound them in a somewhat singular manner: they practise circumcision, persevere in the observance of those customs which are enjoined by the law, and are so Judaic in their style of life, that they even adore Jerusalem as if it were the house of God.
(Ps-)Hippolytus, Haer. 10.17-18;
Cerinthus, however, himself having been trained in Egypt, determined that the world was not made by the first God, but by a certain angelic power. And this power was far separated and distant from that sovereignty which is above the entire circle of existence, and it knows not the God (that is) above all things. And he says that Jesus was not born of a virgin, but that He sprang from Joseph and Mary as their son, similar to the rest of men; and that He excelled in justice, and prudence, and understanding above all the rest of mankind. And Cerinthus maintains that, after Jesus' baptism, Christ came down in the form of a dove upon Him from the sovereignty that is above the whole circle of existence, and that then He proceeded to preach the unknown Father, and to work miracles. And he asserts that, at the conclusion of the passion, Christ flew away from Jesus, but that Jesus suffered, and that Christ remained incapable of suffering, being a spirit of the Lord.
But the Ebionaeans assert that the world is made by the true God, and they speak of Christ in a similar manner with Cerinthus. They live, however, in all respects according to the law of Moses, alleging that they are thus justified.
Ps-Tertullian,
_[Schaff],_EN.pdf]Haer. 3.
After him brake out the heretic Cerinthus, teaching similarly. For he, too, says that the world was originated by those angels; and sets forth Christ as born of the seed of Joseph, contending that He was merely human, without divinity; affirming also that the Law was given by angels; representing the God of the Jews as not the Lord, but an angel. His successor was Ebion, not agreeing with Cerinthus in every point; in that he affirms the world to have been made by God, not by angels; and because it is written, “No disciple above his master, nor servant above his lord,” sets forth likewise the law as binding, of course for the purpose of excluding the gospel and vindicating Judaism.
