雙源假說有個問題，就是它不能說明所有馬太福音和路加福音的疑點。在The Four Gospels: A Study of Origins (1924)一書中，斯特里特（英語：Burnett Hillman Streeter）修改了雙源假說並提出四源假說。此說解釋了雙源假說未能交代完善之處，並 假設馬太及路加福音書有四個來源。包括一個現存來源：馬可福音；及三個未知來源：Q來源、M來源和L[7][8]。

In the Gospel of the Hebrews, written in the Chaldee and Syriac language but in Hebrew script, and used by the Nazarenes to this day（I mean the Gospel of the Apostles, or, as it is generally maintained, the Gospel of Matthew, a copy of which is in the library at Caesarea）, we find，「Behold the mother of the Lord and his brothers said to him, 『John the Baptist baptizes for the forgiveness of sins. Let us go and be baptized by him.』 But Jesus said to them, 『in what way have I sinned that I should go and be baptized by him? Unless perhaps, what I have just said is a sin of ignorance.』」And in the same volume，「『If your brother sins against you in word, and makes amends, forgive him seven times a day.』 Simon, His disciple, said to Him, 『Seven times in a day!』 The Lord answered and said to him, 『I say to you, Seventy times seven.』」Jerome, Against Pelagius 3.2
In the so-called Gospel of the Hebrews, for「bread essential to existence,」I found「mahar」, which means「of tomorrow」; so the sense is: our bread for tomorrow, that is, of the future, give us this day. Jerome, Commentary on Matthew 1
The second rich youth said to him，「Rabbi, what good thing can I do and live?」 Jesus replied，「Fulfill the law and the prophets.」 「I have,」was the response. Jesus said，「Go, sell all that you have and distribute to the poor; and come, follow me.」 The youth became uncomfortable, for it did not please him. And the Lord said，「How can you say, I have fulfilled the Law and the Prophets, when it is written in the Law: You shall love your neighbor as yourself and many of your brothers, sons of Abraham, are covered with filth, dying of hunger, and your house is full of many good things, none of which goes out to them?」And he turned and said to Simon, his disciple, who was sitting by Him，「Simon, son of Jonah, it is easier for a camel to go through the eye of a needle than for the rich to enter the Kingdom of Heaven. 」Origen, Commentary on Matthew 15:14
Gospel of Thomas, Logion 46: Jesus said, "From Adam to John the Baptist, among those born to women, no one is greater than John the Baptist that his eyes should not be averted. But I have said that whoever among you becomes a child will recognize the（Father's）kingdom and will become greater than John."
「There was a certain man named Jesus, about thirty years old, who chose us. Coming to Capernaum, He entered the house of Simon, who is called Peter, and said, 『As I passed by the Sea of Galilee, I chose John and James, sons of Zebedee, and Simon, and Andrew, Thaddaeus, Simon the Zealot, Judas Iscariot; and you Matthew, sitting at the tax office, I called and you followed me. You therefore, I want to be the Twelve, to symbolize Israel.』」Epiphanius, Panarion 30:13
Although several Fathers say Matthew wrote the Gospel of the Hebrews they are silent about Greek Matthew found in the Bible. Modern scholars are in agreement that Matthew did not write Greek Matthews which is 300 lines longer than the Hebrew Gospel（See James Edwards the Hebrew gospel）
They too accept Matthew's gospel, and like the followers of Cerinthus and Merinthus, they use it alone. They call it the Gospel of the Hebrews, for in truth Matthew alone in the New Testament expounded and declared the Gospel in Hebrew using Hebrew script. Epiphanius, Panarion 30:3
「After the people were baptized, Jesus also came and was baptized by John. As Jesus came up from the water, Heaven was opened, and He saw the Holy Spirit descend in the form of a dove and enter into him. And a voice from Heaven said, 『You are my beloved Son; with You I am well pleased.』 And again, 『Today I have begotten you.』 「Immediately a great light shone around the place; and John, seeing it, said to him, 『Who are you, Lord?' And again a voice from Heaven said, 『This is my beloved Son, with whom I am well pleased.』 Then John, falling down before Him, said, 『I beseech You, Lord, baptize me!』 But Jesus forbade him saying, 『Let it be so as it is fitting that all things be fulfilled.』」Epiphanius, Panarion 30:13
Jesus said, "The（Father's）kingdom is like a shepherd who had a hundred sheep. One of them, the largest, went astray. He left the ninety-nine and looked for the one until he found it. After he had toiled, he said to the sheep, 'I love you more than the ninety-nine.'" Log 107
