Featured Is our theology derived mainly from the Gospels or Epistles then?

It's a shame, if you did I probably wouldn't have to be rehashing this with you all over again; you've a very short memory...,

Again, I repeat myself because of your stubbornness, this does not change this fact:

24 But he answered and said, I was not sent but unto the lost sheep of the house of Israel. Mt 15

...or this one:

8 For I say that Christ hath been made a minister of the circumcision for the truth of God, that he might confirm the promises given unto the fathers, Ro 15

Gill:
"...“I am not sent, but to the lost sheep of the house of Israel; as a priest, or as a Saviour and Redeemer, he was sent to make satisfaction and atonement for the sins of all God's elect, and to obtain eternal redemption and salvation for all of them, whether Jews or Gentiles; but as a prophet, in the discharge of his own personal ministry, he was sent by his Father only to the Jews; he was the "minister of the circumcision", Romans 15:8 that is, a minister to the circumcised Jews…..”

I know that you Reformed types have a really difficult time thinking outside your Reformed box, but, have you ever thought what the distinction between these two might be?:

7 but contrariwise, when they saw that I had been intrusted with the gospel of the uncircumcision, even as Peter with the gospel of the circumcision Gal 2

 

Already dealt with. It will help if you read my posts before answering them. But since you are being so dense, here's a little more help for you. The woman recognizes Jesus as Lord and Son of David (v.22). She therefore qualifies as a child of Abraham according to Galatians 3:7. She asks Him to heal her daughter; the disciples ask Him to send her away (v.23). Whose request does He answer?

Also read Matthew 8:8-13 and explain to me why the Lord Jesus healed a Roman Centurion's servant There is no indication that the servant was Jewish.

Romans 15:8-9. 'Now I say that Jesus Christ has become a servant to the circumcision for the truth of God, to confirm the promises made to the Fathers AND that the Gentiles might glorify God for His mercy, as it is written............' The verses convey the exact opposite of what you are trying to make them mean.
Jesus Christ is Prophet, Priest and King over the whole world. '...Is He the God of the Jews only? Is He not also the God of the Gentiles? Yes, of the Gentiles also since there is one God who will justify the circumcised by faith and the uncircumcised through faith' (Romans 3:29-30).

Now you need to answer my points from my last post. What was our Lord doing in 'the region of Tyre and Sidon'? This is by no means in Israel.
Also, He visited the Decapolis, or the area of the Gadarenes, where the inhabitants herd pigs - not very Jewish - in order to heal a demoniac (Mark 5:1-20). He also comes to Samaria, hated by the Jews, to bring salvation to a woman of doubtful reputation sitting by a well. What was He doing in these places?

And I want an answer to this question. Mark 1:15. 'Repent and believe the Gospel.' as a non-Jew, does this apply to me? If so, why?

That our Lord's ministry took place mostly (though not entirely - see above) in Israel is not at issue. The issue is whether His words apply to Gentiles as well as Jews. Do they?

Yet Peter brings the Gospel to Cornelius, and Paul, in every town he visits, makes a bee-line for the synagogue, if there is one, and preaches the Gospel there (Acts 13:14; 14:1; 17:1, 17; 18:4, 19). What the verse means is simply that Peter's ministry was mainly in Israel (though that didn't stop him writing letters to largely Gentile churches) and Paul's was throughout the Mediterranean.

There is one Gospel, and it is for everyone.

 

How so? Peter preached it at Pentecost. The epistles taught the Sermon on the Mount as Jesus interpreted the Law according to it. They also elaborated on Peter's sermon at Pentecost. Peter preached it long before Paul.

 

You doggedly keep doing the same thing, arguing, trying to refute Christ's words instead of understanding Christ's words, "I was not sent but unto the lost sheep of the house of Israel."

For the umpteenth time, the fact that Christ refused no one that came to Him in faith in no way negates His mission as 'a prophet like unto me', sent only to Israel.

Bingo! That's 'the issue'. Rightly dividing. Because He was at once ‘The Prophet’ who warned of the imminent demise of one dispensation and the Author and Mediator of a new one [Hebrews 12:24-29] the issue becomes rightly dividing 'His words'.

In as few words as possible Martin, what's your gospel [good news]? Give me the 'bare bones necessities' to make the hearer happy.

My 'good news' is my signature below.

 

So? Dying for our sins explains it too.

 

Who can be like Moses, and lead God’s people out of Egypt at the last Day?

 

We have it and still miss much of it unless you are Amillennial and a Calvinist.
