Researching The Gospel of the Nazaraeans

I have been researching

The Gospel of the Nazaraeans ("observers") in Hebrew is believed to have been the Hebrew Gospel of Matthew and the source for the present gospel (which was composed in Greek). There are authentic, trustworthy ones who publicly  confirms that this gospel was both used and circulated among the earliest followers of Yahshua in the diaspora. Some believe it originated in Egypt, and that the latest possible date it might have been written was during the first half of the second century; however, there are other opinions that it was composed in the middle of the first century, when "Jesus" traditions were first being produced and collected. An earlier date is more likely than a later one. Jerome, Eusebius, and Hegesippus (the latter two not quoting it) make mention of it as do Origen, Clement (both Alexandrians). It is believed to have been known to Papias who died about 130 C.E. and may have quoted it in his lost "Exegesis of the Sayings of the Lord" (which is now "lost"). It is significant to note that Nicephorus, when drawing up his list of canonical and apocryphal books, stated that the Gospel of the Hebrews contained only 2200 lines, 300 fewer than Matthew. It has been suggested that these three hundred lines are the birth narratives of the first and second chapters of our canonical Matthew.

The Gospel of the Hebrews is a lost text. Cyril, Archbishop of Jerusalem, provides a summary of the text, and a few fragments survive in the form of quotations from patristic authors..
