What gospel did the Pharisees who believed in Acts 15 follow?
The Pharisees who believed followed the Kingdom Gospel, not Paul's Gospel. They acknowledged Christ as who He said He was, yet they still demanded that Gentile believers be circumcised and commanded to keep the Law of Moses, adding law to faith.
Les explains that these people had become believers, but not believers of Paul's Gospel; they had become believers of the Kingdom Gospel, that Christ was who He said He was. The Pharisees who believed rose up saying it was needful to circumcise the Gentile believers at Antioch and to command them to keep the Law of Moses. Les teaches that this is what Paul was constantly up against: Judaizers from Jerusalem would torpedo Paul's message with teaching that you cannot be saved by faith alone. Paul confronted this false teaching as a perverted Gospel, insisting that no man is justified by the law in the sight of God.
But there rose up certain of the sect of the Pharisees which believed, saying, That it was needful to circumcise them, and to command them to keep the law of Moses.
