Mr. BIBLE SCHOLAR I think you have contradicted yourself: Look at this verse:
Salvation is "in Christ Jesus". We are, Paul says, "baptized into Christ Jesus." Thus if there is no baptism, there is no being in Christ Jesus, and no salvation which is found only in Christ Jesus.
Question: How can Hindus, muslims, buddhists and other religions be saved if they are not baptized in Christ?
Paul says in Rom. 6:3, "as many of us as were baptized into Christ Jesus" so he says the same thing again that he had said in Gal. 3:26-27. One is baptized into Christ. Salvation is in Christ.
