There are few less convincing ways to set the context of a sentence than by pulling sentences out of another letter. Your quote has NOTHING to do with Paul’s argument in 1 Cor 3, and NOTHING to add about who is the builder and who is the building, or who is the planter and who is the field being planted.
But then, it doesn’t take much context to understand 1 Cor 3, since a hired hand planting a field is NOT the field itself, and the architect of a building is not the building itself. That is just excruciatingly obvious. To deny it is to fly off into La-La Land.
It seems to me that your interpretation thinks a field of earth can be saved with the foundation of Jesus the Messiah but not a man. It seems to me that your view would cling to a personal interpretation of a small portion of First Corinthians, while ignoring and or denying the same author's words elsewhere.
