ISB ~ Galatians 3 v2
hearing with faith?:The Galatian controversy turns on the question of when they received the Holy Spirit. Since this happened when they believed the gospel and were baptized (Acts 2:38), Paul deems it foolish to accept circumcision and other works of the Mosaic Law as additional requirements needed to complete their Christian initiation. This is the very logic set forth by Peter at the Jerusalem Council (Acts 15:811).
