Daniel Unterbrink proposes a lot of unique ideas in “Judas of Nazareth” but the most compelling is that Paul inspired the Synoptics – the writing, the editing, and the whole narrative.
It is Unterbrink’s assertion that Paul lived past the persecution of Israel from 68-72 and helped to compose Mark’s gospel. His reasoning is simple: the gospel displays Pauline themes interwoven throughout the book. The same is also said of Matthew and Luke, who borrow 50%+ from Mark.
It’s a reasonable assertion since Paul’s key writings (Galatians, Romans, and the Corinthians) all pre-date the Synoptics by several years.
Unterbrink see’s Paul as introducing a Jesus messiah (Christ) that does not resemble the actual historical Jesus of Peter and James. So Paul’s ‘revealed gospel’, which differs from that of Jesus’ brother and disciples, takes on gentile qualities for the sake of a wider audience.
I agree with much of that assertion after studying the Jewishness of Jesus myself.
There is no way Jesus taught the things Paul teaches since Paul is in conflict with the early community in Acts 15 and in Galatians 2. Paul plays that original community down, even declares they are wrong, within his version of the ‘revealed gospel’ he’s received (via visions).
Much of the gentile flavour we find in the Synoptics (and John) can be clearly attributed to Paul’s message and writings – from the Lords Supper to the resurrection to inclusion of the Gentiles.
If the writing of the letters of Paul are accurately aged (60’s) then they easily pre-date the gospels (70-100+) and could have inspired their creation, thoughts, and formation of Jesus’ life and wording.
That’s not absurd thinking, that’s normal rationale of following the influence of who wrote first.
