The story of Jesus might have been different if Joseph and Mary had been sent back to Israel from Egypt because they were considered "undocumented workers," or worse, "illegal aliens."
I think that there is something powerful in simply considering Christ as a criminal defendant. That subtle change in perspective can change worlds.
I do not believe that capital punishment belongs in our world. The arguments of "crime determent" and "continuing threat to society" are masked justifications for a human response to justice, not a divine one.
