Matthew 2:23
And he came and dwelt in a city called Nazareth, that what was spoken by the prophets might be fulfilled: He will be called a Nazarene.
It is widely known that academics were unable to find this reference in the Hebrew Bible. Some time ago I raised the thesis that Matthew 2:23 refers to the oral tradition also mentioned in Luke 2:25-39, in which the word Nazareth occurs; "propheses" and Simeon, the two are equivalent to the "prophets" of Matthew 2:23.
What am I saying with this? Let's make it clear:
It is possible that there was an oral tradition in the Church of the Circumcision (Acts 20:20-27), this is the conclusion when understanding Matthew 2:23 and Luke 2:25-39
It is also possible that there was NOT this oral tradition, but I do not agree with this possibility.
"The Didache" refers to an early Christian document also known as the "Doctrine of the Twelve Apostles." It is generally dated between the years 70 and 150 AD, it does not show any clear access to the canonical Gospels...
Papias, who lived between the years 100 and 130 AD, is known to be familiar with the rumored origins of two writings that bear similarities to the Gospels of Mark (associated with Peter) and Matthew.
Aristides, who lived between the years 120 and 130 (or 140 AD), makes mention of a book entitled 'Gospel', whose full name is not specified, in which the figure of a virgin is described. This book, apparently, was known and possibly available to the public at the time.
Patristic Collection vol. 20 - Origen Against Celso Ed. Paulus
"Here is the first affront formulated by Celsus in his desire to defame Christianity: Disregarding established laws, Christians form secret conventions among themselves. Among the conventions, some are public, and all are in accordance with the laws; others are hidden, and they are all those whose implementation violates the established laws."
This certainly explains why the Gospels do not appear in Christian records until Justin Martyr in 150 AD. The Church of the Circumcision (Acts 20:20-27) served and worshiped in the Temple, what is the possibility of another Christological "god"? Celsus is also the first recorded pagan writer to have access to the 180 AD Gospels and criticize them.
Confirmed existence of the Gospels:
Justin Martyr, around 150 AD, makes reference to several books entitled "Gospels", including the memoirs of the Apostles and the reminiscences of Peter.
Justin Martyr died around 163 AD and it is conjectured that his disciple Tatian possibly received the literary inheritance of his writings.
Tatian 172 AD possibly produces the harmony of the Gospel 'From the Fours', but does not mention the names of the authors.
Irenaeus 180-190 AD – he is the first to name all four Gospels.
If this conjecture is correct, did the Gospels already exist in 70 AD? Were they hidden and for private use? As we understand when we read Celsus' comment regarding the Jewish Assembly, because the gospels have a divine Christology and so as not to create an "environment" of confusion and persecution on the part of the majority of unconverted Jews... Or do the gospels really Were they written after 70 AD?
