He was an apostle (v. 1b). This word means “one who is sent by authority with a commission.” It was applied in that day to the representatives of the emperor or the emissaries of a king. One of the requirements for an apostle was the experience of seeing the risen Christ (1 Cor. 9:1-2). Paul saw Christ when he was on the road to Damascus (Acts 9:1-9), and it was then that Christ called him to be His apostle to the Gentiles. Paul received from Christ divine revelations that he was to share with the churches.
