Are you denying that Paul was the last one to see the resurrected Lord? Are you saying that he could see the Lord, but not the "resurrected Lord"? Are there two Lords?
Give it up Pet. Paul was a witness to the resurrection. The context of 1 Cor 15 leaves no other conclusion.
Either Paul saw the risen Lord or Paul is not and never was an apostle. If he did not see the risen resurrected Lord, then he was an imposter.
"For we have not followed cunningly devised fables, when we made known unto you the power and coming of our Lord Jesus Christ, but were eyewitnesses of his majesty." (2 Peter 1:16 KJV)
Was Paul one of the "we"?
This is your definition of an apostle, not the Bible's. But I see that you are continuing to dance around the question of the nature of the Biblical offices of episkopos, presbuteros and diaconos. I guess this is only natural since your church cannot claim to posses them.
