... I could show you the verses in the NT that tell us Christ made us all two "tribes", the sheeps and the goats, the wheat and the tares, the the children of God and the children of the devil, the damned and the saved and he no longer recognizes Jew or gentile..
whoa whoa whoa J slow down
yes, there are two folds of the same flock, the Jews under sacred scripture and the Gentiles under natural laws by conscience (see Romans)
But that does not mean the Gentiles are necessarily children of the devil.
If Jews and Gentiles become divided from each other, instead of being one in Christ and governed under Jesus in harmony, then we all become victims of the devil from that ill will.
That happens to people of all folds, of any tribe, if we fail to be reconciled in Christ to overcome such ills that you will find in all groups and institutions, because it is in all people.
Jesus fulfills BOTH these branches, the divine laws of God and the natural laws of Man.
See Col 1:16 that all authorities are created by and given unto the Lord, so that is why Jesus is called Lord of lords, or authority over ALL LAWS, both of man and God.
We can all receive Christ and be joined as one with God, yet still be of our respective tribes and cultures. The people brought up Secular Gentile, may still use that line of understanding and that system to work with, even as children of God governed by Jesus.
Christ makes all things new, so nothing has to be fallen to Satan or the Devil's influence.
All things even the secular gentiles under natural laws, even nontheists, can receive God through Christ yet retain their current systems that GOD created them to use for a reason.
See Romans 8:28 that all things can be used for Good, for God's purposes.
You give the Devil too much credit.
The Devil can corrupt anything, even Christian institutions and teaching, but so can anything be redeemed and fulfill the jurisdiction and dominion of Jesus and God.
You don't have to demonize the entire group or lineage, that comes from fear manipulated by the Devil to cut us off from each other with unforgiveness to try to block God's will.
Where we forgive and give all things over to God through Christ, you will see, there is nothing that God cannot reclaim and use for great purposes that fulfill his greater good will.
