He was not exactly a parishioner
When the bishop arrived at his assigned destination, he was greeted with reverent enthusiasm by people at the very highest levels.
The bishop returned the favor by giving strong affirmation to his host and, consistent with his mission and his conscience, passed on a message of peace and kindness (while still upholding truth).
After the bishop returned from his mission, the powerful man went into a rage, threw the bishop into prison, and deprived him of food and water.
John, the first Bishop of Rome to use that name, died there on this very day in the year 526.
