Very sloppy posting on my part, my apologies. Paul was converted to talk to the Gentiles. Paul was the only Apostle to the Gentiles.
(Also, I should have written that Joesph and Mary (were) Jews).
As you probably know, some folks think Paul was not technically "a Jew" because he was not from the tribe of Judah (he was a Hebrew from the tribe of Benjamin and studied under Gamaliel).
Might be nit picking your phrasing, but it also worth pointing out that Paul was not one of the original 12 Disciples of Jesus, nor even one of the original 12 Apostles, but rather an "apostle of the Gentiles" as he himself phrased it. He only encountered Jesus after the crucifixion on the road to Damascus.
While I feel confident you know these details, the terms Disciple and Apostle are often conflated (even within the Gospel of John) so this might be helpful for others.
