What did Paul communicate to the leaders in Jerusalem?
Paul communicated to the leaders in Jerusalem the gospel he preached among the Gentiles, showing it was not connected with Judaism. He went up by God's instruction to meet with them, and the gospel he passed on was revealed from the ascended Lord, not from the Twelve's earthly ministry.
Les explains that in Galatians chapter 2, Paul went up to Jerusalem to convince the 12 that his gospel to the Gentiles was not connected with Judaism. He went up again by revelation, meaning God instructed him to go up to Jerusalem and meet with the 12. Paul communicated unto them that gospel which he preached among the Gentiles. Les emphasizes that everything Paul revealed to pass on to the Roman world was revealed from the Ascended Lord in glory—not from the 12, not from the earthly ministry of Christ, but from the Ascended Lord. The same word is used again in I Corinthians 11:23.
