I never knew there was a “Vineyard” movement but it doesn’t surprise me. People have to start all sorts of things. It is interesting from your post that they accept all theological views except the ones they disagree with. Ah, ecumenticalism!!! Toss doctrine out the window for the sake of love, love, love.
Reviewing the passages, “new vineyard” was probably an inaccurate term. As boatbum points out from the text of Romans, the branches from the house of Israel were cut off and the Gentiles were grafted on as foretold by Isaiah 5 and 27 and John 15. To be more precise, the vineyard talked about in scripture is a continuation of God’s election and chosen people (our Jewish forefathers and Gentiles). A pleasant vineyard that the Lord will keep. But I’m sure it has nothing to with this church.
