Is Paul's gospel in opposition to Jesus' teachings or just different?
Paul's gospel is not in opposition to Jesus' teachings; it is a difference. It moves from Law to Grace while serving the same God and the same Christ. It is an extension of Jesus' teachings, not a contradiction, as Paul's ministry to the Gentiles shows.
Les explains that Jewish believers had come in by the Kingdom economy and the Kingdom Gospel, while Paul went in a different direction, yet still serving the same God. He rejects the claim that Paul was in complete contradiction to Jesus. The difference is not opposition but dispensation: it is not under Law but under Grace, and it concerns the same God and the same Christ. Paul's apostleship to the Gentiles is an extension of Jesus' teachings, not opposition to them.
