Interestingly, the author of the epistle to the Galatians implored a forensic rhetorical device in his day to make his arguments, and, this methodology is considered in this book, especially in taking a look at the beauty of the precise judicial proceedings followed by the author in his argument in chapter three of Galatians. This research reveals Apostle Paul's evidences for justification by faith which are the experiential, scriptural and logical arguments. The social rhetorical criticism, as methodology is being followed in this research.
