Not according to Ro 11:16 where the roots are the
firstfruits of God's people (the tree), which are the patriarchs.
Botany 101: Branches aren't grafted into roots, they are grafted into trunks.
We're talking tree as God's people here, not as a system of life.
The roots (patriarchs) produce the trunk (Christ) in which the branches (the people of God) abide, as they do in the vine (Jn 15:5).
Don't let your eschatology govern your doctrine.
