As we read Paul’s epistles, it becomes clear that Paul was exceedingly familiar with the instructions Jesus gave His disciples in Luke 10 as they went to the villages and towns of Israel.
Thankfully this article collates key ideas and demonstrates that point.
Usually Paul is accused (or used to be accused) of “fabricating Christianity” and taking it beyond the words of Jesus.
That seems increasingly unlikely if Paul was such a diligent student of Jesus’ method of sending and training disciples.
