We have the disciples of Christ and then we clearly have the Disciples of Paul. Christians are the the ones that follow the words and example of Christ.
I happen to believe that Paul is right, but is grossly misinterpreted by Christianity today...as he was in biblical times:
2Pe 3:15 and regard the patience of our Lord as salvation; just as also our beloved brother Paul, according to the wisdom given him, wrote to you,
2Pe 3:16 as also in all his letters, speaking in them of these things, in which are some things hard to understand, which the untaught and unstable distort, as they do also the rest of the Scriptures, to their own destruction.
Peter recognized that even then Paul's writings were being distorted and twisted in order to do away with the law of God.
