It must be noted that all claims that there are authentic Pauline Epistles are products of propaganda. No evidence has ever been presented by anyone at anytime to show that an actual person called Paul, a supposed Pharisee of the tribe of Benjamin, ever lived in the time of Aretas.
Contemporary Non apologetic sources do not mention any character called Paul and his Epistles and the earliest manuscripts with so-called Pauline letters [P 46] were written sometime in the 2nd-3rd century.
In addition, the claim that a character called Saul/Paul became a believer after he was blinded by a bright light and spoke to the resurrected non-historical Jesus is an invention.
Paul the convert was manufactured
Now, we have the short gMark--the earliest version of the Jesus story.
The author of the short gMark did not know of post-resurrection visits and the commission by the resurrected Jesus to preach the Gospel.
In the so-called Pauline Epistles it is claimed over 500 persons were seen at once by the resurrected Jesus---not even the author of Acts, a supposed close companion of Paul record such a story.
Justin Martyr a supposed 2nd Christian century writer wrote nothing of Paul and the post-resurrection visit of 500 persons by Jesus.
Justin Martyr appears to know a post-resurrection story similar to gMatthew where it is claimed that the disciples stole the body of Jesus.
Diaologue With Trypho CVII
...... his disciples stole him by night from the tomb, where he was laid when unfastened from the cross, and now deceive men by asserting that he has risen from the dead and ascended to heaven.
Celsus a 2nd century skeptic wrote nothing of Paul and the post-resurrection visit of over 500 persons by Jesus.
Celsus claimed that only one woman and his boon companions were secretly seen by Jesus after the resurrection.
Origen Against Celsus 2.70
but when he might have produced a powerful belief in himself after rising from the dead, he showed himself secretly only to one woman, and to his own boon companions..
Against Celsus 1.63
And I do not know how Celsus should have forgotten or not have thought of saying something about Paul, the founder, after Jesus, of the Churches that are in Christ.
Paul and the so-called Pauline Epistles were manufactured after the short gMark, after the writings attributed to Justin and Celsus.
