Is Salvation for Hebrews Only? Misinterpreting the Hope & Scope of the Gospel

Is salvation for Hebrews only? It is my judgment that the doctrine of Hebrew Israelites is taking us back to the dark ages. Their preoccupation with the Law of Moses, doctrines of meats, and literal feast days is a step backwards. Self-identify, self-esteem and cultural awareness is one thing, but when you begin to kill lambs as a demonstration of your allegiance to God, that is a step over the line. It denigrates Christ, his death and sacrifices and turns the truth on its head. Misinterpretations of the hope and scope of the gospel.
