According to Paul he did.and Peter supported him.
2 Peter is most likely a forgery. Look it up. The near unanimous consenses is that it is an attribution and not authentic to Peter. That said, it is also a slap in the face to Paul under the complement. 2 Peter undercuts Paul's teaching by telling the reader that Paul is too hard for people to understand and that it will lead to their damnation. That the reader is to listent to their elders in the guidence of interpreting Paul. Or, in the words of Tertullian, "Paul is the apostle of the heretics.."-See the heresy of Marcion.
The gospel of Paul and the gosple of Jesus are not only different, but are mutally exclusive of one another.There is only one gospel for them all to share the right hand of fellowship.
