Newsflash for Jim: Paul never met Jesus! You are taking Paul's hearsay over the actual words of Jesus himself.
Yes, St Paul did so meet Jesus, at a minimum on the road to Damascus.
But I think it obvious that St Paul also saw and head Jesus sermons given that Jerusalem was only a town of about 80,000 people at the time according to Josephus, and that St Paul was a very zealous persecutor of Christians and worked for the Sanhedrin.
According to Acts chapter 26:
Then Agrippa said to Paul, “You are permitted to speak for yourself.”
So Paul stretched out his hand and answered for himself: 2 “I think myself happy, King Agrippa, because today I shall answer for myself before you concerning all the things of which I am accused by the Jews, 3 especially because you are expert in all customs and questions which have to do with the Jews. Therefore I beg you to hear me patiently.
4 “My manner of life from my youth, which was spent from the beginning among my own nation at Jerusalem, all the Jews know. 5 They knew me from the first, if they were willing to testify, that according to the strictest sect of our religion I lived a Pharisee. 6 And now I stand and am judged for the hope of the promise made by God to our fathers. 7 To this promise our twelve tribes, earnestly serving God night and day, hope to attain. For this hope’s sake, King Agrippa, I am accused by the Jews. 8 Why should it be thought incredible by you that God raises the dead?
9 “
Indeed, I myself thought I must do many things contrary to the name of Jesus of Nazareth. 10 This I also did in Jerusalem, and many of the saints I shut up in prison, having received authority from the chief priests; and when they were put to death, I cast my vote against them. 11 And I punished them often in every synagogue and compelled them to blaspheme; and being exceedingly enraged against them, I persecuted them even to foreign cities.
So St Paul was deeply involved in persecuting Christians and was acting against the 'authority' of Jesus, meaning he was acting contrary to the stated goals and plans that Jesus spoke of.
A town of 80,000 people is not even as big as an NFL football stadium capacity. That one could suggest that a famous teacher and miracle worker like Jesus could come into town and preach for weeks without St Paul ever going to see Him is ludicrous. That one could read of St Pauls active engagement with the Sanhedrin in arresting and persecuting Christians and handing them over to be killed, while living in Jerusalem himself, and to NOT have been there at the trial and conviction of Jesus I think highly unlikely. Jerusalem and all of Israel was so small there was no difficulty in St Paul meeting Jesus, none at all.
Yes, St Paul most certainly heard Jesus speak and probably met Him and confronted Him, so zealous was ST Paul for Judaism and his people that he would have confronted this man he regarded as an imposter and a threat to his nation.
