Romans 11:11 I say then, Have they stumbled that they should fall? God forbid: but rather through their fall salvation is come unto the Gentiles, for to provoke them to jealousy.
The only way for the Romans to continue in God's goodness would be for them to be stablished into the Body of Christ according to:
Romans 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,
Romans 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:
Romans 16:27 To God only wise, be glory through Jesus Christ for ever. Amen.
That is why Paul longed to see them:
Romans 1:11 For I long to see you, that I may impart unto you some spiritual gift, to the end ye may be established;
Romans 1:12 That is, that I may be comforted together with you by the mutual faith both of you and me.
...
I see, so you are hinging your whole fallacy that the Church that Christ built on Peter and the apostles (including Paul!) was to be 'cut down' and replaced on the word 'established' here in the KJV?
Again, context, context, context.
It is clear from the preceding verses that the Church in Rome was ALREADY established in Faith, in fact a faith that was 'heralded throughout the world.' Thus the translation that reads 'strengthened' here is a more appropriate rendering of the greek text.
There is no tree today, but a new creature (2 Corinthians 5:17 KJV), the church (with Christ the Head), which is His Body, the fulness of Him that filleth all in all (Ephesians 1:22-23 KJV)
I'm sorry, I do not see how you can speak about the Body of Christ and somehow reject the fact that God saved HIS people (the remnant of Israel that believed) and grafted into THEM the gentiles who believed. That is clearly Paul's message about the cultivated and wild olive trees.
That Jesus Christ is the Messiah of Israel, The Son of God who suffered and died for us, and for our salvation, and rose again to new life. In HIM we have the hope of eternal life!
Here is how John puts it:
John 3:16 'For God so loved the world that he gave 7 his only Son, so that everyone who believes in him might not perish but might have eternal life.'
Peace!
