Paul started as a persecutor before converting;Stephen is a more correct comparison to Charlie.
Paul was sent to the gentiles, or what we might label as irreligous.
Steven was speaking to people steeped in religous practice.
Steven chastised the religous people for not believing a God they claimed to know.
Paul’s message was different. I know that in his epistles he wojld come down hard on his audience when he needed to. But that was because they were nit doing what they knew to be right.
I see Charlie more like I see Paul reaching out mercifully to the lost.
And Stephen’s death - murder/stoning as a martyr. Paul didn’t die young, AFAIK.
