Well first off you have totally misrepresented what I said in my post. But we can put that aside.
(Luke 4)
17 and the scroll of the prophet Isaiah was handed to him. Unrolling it, he found the place where it is written:
18 “The Spirit of the Lord is on me,
because he has anointed me
to proclaim good news to the poor.
He has sent me to proclaim freedom for the prisoners
and recovery of sight for the blind,
to set the oppressed free,
19 to proclaim the year of the Lord’s favor.”[

20 Then he rolled up the scroll, gave it back to the attendant and sat down. The eyes of everyone in the synagogue were fastened on him. 21 He began by saying to them, “Today this scripture is fulfilled in your hearing.”
Also, through faith asked something along similar lines so I will give you that reply here also.
I believe this is were you go wrong. We know that the gospel call started in Jerusalem, so the majority of brothers in Christ at first were Jewish.. so that straight away disproves your theory of 2 gospels one for Jews and one for gentiles.
There was a 3 year or so transition period between Jesus' earthly ministry and the cross, and then the spreading of the one true gospel from Jerusalem out to the whole world where it still being spread.
Paul teaches us that in Christ we gentiles have been included into the citizenship of God's people.
There is one Gospel and one people of God.
For he himself is our peace, who has
made the two groups one and has destroyed the barrier, the dividing wall of hostility, 15 by setting aside in his flesh the law with its commands and regulations. His purpose was
to create in himself one new humanity out of the two, thus making peace, 16 and
in one body to reconcile both of them to God through the cross, by which he put to death their hostility. 17 He came and preached peace to you who were far away and peace to those who were near. 18 For through him
we both have access to the Father by one Spirit. (Ephesians 2)
You see as I said before
all scripture points to Jesus. His life, death and resurrection.
Now the as with throughfaith, the burden of proof is on you to show that Jesus taught a different gospel than Paul and that there are two separate peoples of God. BTW, throughfaith never answered..will you?
