But this dismisses the view of Ebion (and Jewish Christians), i.e., that Jesus was "nothing more than a Solomon or a Jonas — as Ebion thought we ought to believe concerning Him."Tertullian's On the Flesh of Christ 18
Now, that we may give a simpler answer, it was not fit that the Son of God should be born of a human father's seed, lest, if He were wholly the Son of a man, He should fail to be also the Son of God, and have nothing more than a Solomon or a Jonas, Matthew 12:41-42 — as Ebion thought we ought to believe concerning Him. In order, therefore, that He who was already the Son of God— of God the Father's seed, that is to say, the Spirit— might also be the Son of man, He only wanted to assume flesh, of the flesh of man without the seed of a man; for the seed of a man was unnecessary for One who had the seed of God. As, then, before His birth of the virgin, He was able to have God for His Father without a human mother, so likewise, after He was born of the virgin, He was able to have a woman for His mother without a human father. He is thus man with God, in short, since He is man's flesh with God's Spirit — flesh (I say) without seed from man, Spirit with seed from God.
1. It was not fit that Jesus should be born of a human father's seed.
2. The seed of man was unnecessary for his birth.
3.Jesus was able to have a woman for his mother without a human father.
4. Jesus had flesh without seed from man.
5. Jesus was the seed of God.
On The Flesh of Christ, like other Christian writings, confirm there was never any documented history that Jesus had a human father.
It is for that very reason that Marcion could preach without fear of contradiction that the Son of God was without birth and only appeared to have flesh.
There was never any documented history at any time of a known human father of Jesus.
Jesus was always a product of belief--never a product of history.

As Eusebius says in EH 3.27.2, "For they [Ebionites] considered him a plain and common man, who was justified only because of his superior virtue, and who was the fruit of the intercourse of a man with Mary."
