2-3] One clear example of the connection between the gospels is the story of the man who was sick of the palsy (Mark 2:1-12, Matt 9:1-8 and Luke -26).The accounts are so similar that even a little parenthesis -"he said top the paralytic"- occurs in all three accounts in exactly the same place.The book concludes with Paul at Rome awaiting trial before Caesar.
Each of the first three Gospels contains predictions by Jesus concerning the destruction of Jerusalem and the Temple (Matthew 24; Mark 13; Luke 21), but none records the fulfillment. Hence, the composition of the first three Gospels most likely occurred sometime before this event, otherwise their destruction would have been recorded.
So considering that the oldest copies of the gospels are dated to around 400 AD (I'm thinking of the Codex Sinaiticus), how do scholars go about estimating the date of composition of the gospels?
I mean I'm sure there are some textual clues; I mean I assume the usage of Koine would probably change somewhat over 300 years but are there other clues that scholars use to estimate the general time of composition?
The evidence shows that the four Gospels were written in a relatively short time after the death and resurrection of Jesus Christ.
Examining the internal evidence of the New Testament itself can make this plain.
