His opponents were discredited and disabled by the dispersal of the church of that city just before the destruction of Jerusalem in A.D. 70 throughout the church Paul was a strong opponent with his letters and the gospel. He became the foundation of the Christian movement. Paul teaching for life in this day and age can be brought out in a summary of four of his leading themes. Religion is not rules and regulations. GOD does not deal with His children that way, but He accepts them freely when they respond to His love.
People matter more than things, principles, and causes.
The highest of principles and the best of causes exist only for the sake of people personal liberty itself is abused if it is exercised against the personal well being of others. Discrimination on the ground of race, religion, class, or sex is an offense against GOD and humanity alike. That was a great comfort to Christians whose friends and family had died. Paul's message is a message of reconciliation. Paul presents this teaching with his own emphasis.
