Is James authoritative?Living and saving faith alone...makes us right with God.
Such a faith will always produce obedience if given the opportunity.
Rom 4:5, But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness.
Rom 4:6, Even as David also describeth the blessedness of the man, unto whom God imputeth righteousness without works,
Jesus said that He would send the Holy Spirit who would guide the disciples into all truth (John 14:26, John 16:13). This is what makes such epistles as 2 Peter authoritative.
It is 2 Peter 3:15-16 that makes Paul's writings authoritative.
And Paul's statement in 2 Timothy 3:16-17 makes everything else in scripture authoritative.
Is what JESUS said authoritative?
Please show me somewhere in the N.T. where Jesus said to just believe in Him and we would be saved.
As far as working not...Romans 4:5
What kind of work do you think Paul was speaking of?
