Here we can see that both Jews and Gentiles are baptized into the Body of Christ:
I don't think anyone denies that. Paul, himself, was a Jew.
All of the Jewish believers living in the first century did indeed call on the name of Jesus Christ so therefore all of them belonged to the Body of Christ.
All of them? Even those who John said had no truth in them? Those who John said walked in darkness "even now"?
Just wondering. Please don't feel pressured into answering.
