I think that getting fired by the Pope would pretty much wrap up your career.
Carlo Maria Vegan, Vatican Ambassador to the United States, was fired by the Pope for blindsiding him with a meeting with Kim Davis during his visit to the US. Davis is the county clerk jailed for refusing same-sex marriage licenses in Rowan County, Kentucky.
With his age and recent termination, he would most likely only qualify to be a greeter at Walmart. Even that might be a stretch. At least the interview would be funny. “So, what was your last job?” “The Vatican Ambassador to the United States”. “Ha ha. Seriously, what did you do”?
Then he would need to be clever about his reason for leaving. You can’t just say that you were fired by the Pope. Maybe, “Um, tithing has been down so they had to downsize”. Or “The Pope just didn’t like me”. Or maybe “I made fun of his hat”.
Whatever the reason, I just don’t think gainful employment is in his future.
