Was the gospel Paul preached received from men?
No. Paul certifies that the gospel he preached is not after man. He did not receive it from the Twelve in Jerusalem, from a seminary, or from a denominational leader. Instead, he received it of the Lord, as he states in 1 Corinthians 11:23.
Les explains that Paul's gospel was not received from men. In 1 Corinthians 11:23, Paul writes, 'For I have received of the Lord,' indicating he did not get it from the Twelve in Jerusalem, from some seminary, or from a denominational bigwig. Les then directs us to Galatians 1, where Paul certifies that the gospel he preached is not after man. This confirms Paul received his gospel directly from the Lord, not from any human source, which is essential to understanding his apostleship.
But I certify you, brethren, that the gospel which was preached of me is not after man.
