The people of the region saw that there was great power in the name of Jesus,
"The bible is an old fiddle on which any tune can be played." That's how they explain everything!
IMHO, Paul did to Jesus' teachings the same as Rutherford did to Russell's teachings. Teachings that started out as gentle, kind, and humane got changed by the next guy in line of authority. Paul often mentioned Jesus teachings because he saw
'great power in the name of Jesus" but he also added his own version and twist on things. He used the "Jesus power and persuasion" as a segway to take over and promote his own ideas into the "christian " congregations. Most 'christian' doctrine today is basically Pauline dogma. He wrote most of the greek scriptures which reflect his world view of how things should be.
Rutherford did the same thing to Russell's religion. He muscled his way in and took over. He used what Russell amazing was able to get started and often mentioned Russell in endearing terms, because he saw " great power in the name of CT Russell"/ until he gained full control. His writings dominated the organization for many decades until thankfully he died.
Sorry if I got of track!
just saying!
