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

The Sermon on the Mount is the doctrine of Christ apart from which none can be saved. This according to Matthew 7:28 and 2 John 9

All NT ethics come from it with much of it imported into the Epistles. Paul quotes it. If you obey the Ten Commandments in love, not as the Pharisees, you get New Testament ethics found in the Epistles.

 

only the saved believed it. It was instruction but broadened when it went to the gentiles.

 

This is much more to the point than just citing the whole Bible, which sounds more like a copout.

The OP points to an important fact: we all start somewhere when developing our understanding, that is, every point cannot be primary or of equal importance.

Also, everyone has their own background before coming to faith. Some start with more Bible experience than others, which can be both useful and detrimental.

 

In context, it's all the counsel of God in relation to all the counsel of the mystery that God revealed to Paul.

 

DISCLAIMER: The study I'm about to present in no way means that we should not read and learn from the entire Bible.

Paul is the apostle to the Gentiles:

(Acts 9:15, 26:15-18), Ro.11:13, 15:16-18, Gal.2:7-9, Eph.3:2, 1Ti.2:7, 2Ti.1:11, 4:17

The mystery of the church was revealed to Paul:

Eph.3:1-9

We should listen to him to understand the rest of the Bible and glorify God:

Ro.16:25-27, 1Co.11:2, 2Ti.1:13, 2:2, 7; 3:14

Paul is our pattern:

1Ti.1:16, 2Ti.3:10

We should follow him:

1Co.4:16, 11:1, Php.3:17

He has his own gospel:

Ro.2:16, 16:25; 1Co.1:17, 9:17, 15:1 (different than what the rest preached for see 2Tim.2:8), (2Co.4:1-3 2Th.2:15…our gospel); Gal.1:6-17, 2:2,5,7, Php.4:15, 1Tim.1:11, 2Tim.2:8, Titus 1:3 his word...is committed unto me

He has his own doctrine:
Act 2:42 And they continued stedfastly in the apostles' doctrine and fellowship, and in breaking of bread, and in prayers. VS 2Ti 3:10 But thou hast fully known my doctrine, manner of life, purpose, faith, longsuffering, charity, patience,

He taught us his own traditions by his epistles which we should follow:

2Th.2:15, 3:6

Verses that teach that we are to interpret the Bible according to Paul’s epistles:

3 times Paul uses the expression according to my gospel (?)

Rom 2:16 In the day when God shall judge the secrets of men by Jesus Christ according to my gospel.

Rom 16:25 Now to him that is of power to stablish you according to my gospel, and the preaching of Jesus Christ, according to the revelation of the mystery, which was kept secret since the world began,

Rom 16:26 But now is made manifest, and by the scriptures of the prophets, according to the commandment of the everlasting God, made known to all nations for the obedience of faith:

He will use the word according again in 1Timothy:

1Ti 1:8 But we know that the law is good, if a man use it lawfully;

1Ti 1:11 According to the glorious gospel of the blessed God, which was committed to my trust.


2Ti 2:7 Consider what I say; and the Lord give thee understanding in all things.

2Ti 2:8 Remember that Jesus Christ of the seed of David was raised from the dead according to my gospel:

2Ti 2:9 Wherein I suffer trouble, as an evil doer, even unto bonds; but the word of God is not bound.

 

​

You trying to be 'cute'?:

21 And they asked him, What then? Art thou Elijah? And he saith, I am not. Art thou the prophet? And he answered, No. Jn 1

22 Moses indeed said, A prophet shall the Lord God raise up unto you from among your brethren, like unto me. To him shall ye hearken in all things whatsoever he shall speak unto you.
23 And it shall be, that every soul that shall not hearken to that prophet, shall be utterly destroyed from among the people. Acts 3

You're not cute. You're showing your ignorance.

 

He also said, "O woman, great is your faith! Let it be to you as you desire." He was testing the woman to draw out her faith. Se also Matthew 8:5-13. Maybe the woman was of the house of Israel after all (Romans 2:28-29).
So which of our Lord's words do you not wish to obey?

 

I am a Syro-Phenician Greek exactly like her. And Christ basically called us dogs. He wasn't testing her faith.
He crossed dispensational lines (because he is the Lord of dispensations, just like of the sabbath) and allowed her an exception out of due time because of her humility.

 

He had already healed the centurion's servant as I pointed out above, and several Samaritans. 'For so God loved the world that He gave His only begotten Son.' Moreover, in Christ the middle wall of separation between Jew and Gentile is broken down. He, Christ, has made both (Jew and Gentile) one. Read Galatians 3:27-29. You and I are both Abraham's seed, not by some wretched ethnicity, but by faith.

 

"She approached Him, He was NOT sent to her or any other non-Jew. There were other non-Jews that approached Him in faith but in no way does that negate His mission as 'The Prophet', sent only to the lost sheep of the house of Israel."
Matthew 5:17 - 18 - a closer look

You'll have to explain that one. Have no idea where you're coming from.

 

I have preached Gospel sermons several times on Matthew 5:20. And the rest of the chapter is application of that verse.

 

"Now to him who is able to establish you in accordance with my gospel, the message I proclaim about Jesus Christ, in keeping with the revelation of the mystery hidden for long ages past, but now revealed and made known through the prophetic writings by the command of the eternal God, so that all the Gentiles might come to the obedience that comes from faith—to the only wise God be glory forever through Jesus Christ! Amen" (Romans 16:25-27).

This seems a key passage in how to develop our understanding and meshes with KR's signature verses from Luke 24. The important keys to Scripture, or revelation of prophecies, were not provided until after the resurrection, and only disseminated with the arrival of the Holy Spirit on Pentecost.

 

All of scripture points us to the Redeemer. All the covenants of God shed light on his redemption.
Sadly, the attempt to designate parts of scripture over others is a favorite pastime of dispensationalists. However, there is no justification for it in scripture.

 

Theology refers to the study of God. Therefore the whole Bible must be studied to know as much as possible of God. Now to become Christ-like the Gospels are extremely helpful, as we are to learn "all that He commanded." For example, not using coarse language, and exercising self control over our tongue seems unknown to many who post gratuitous insults to bolster bogus argument.

 

I haven't had time to look at your link (40th Wedding anniversary today!), but if you look through the Gospels, I think you'll find that most of the people healed either came to our Lord or were brought to Him; He didn't have to go looking for them (e.g. Mark 1:32-34; 5:53-56).
Secondly, what was He doing in 'the region of Tyre and Sidon'? This is by no means in Israel.
Thirdly, 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). Fourthly, He comes to Samaria, hated by the Jews, to bring salvation to a woman of doubtful reputation sitting by a well.

If Jesus is a Prophet only to the Jews, what does He have to say to you or to me who are not Jewish? Do we have to obey His words?
