Like Peter, Pope Augustine dresses in lay clothes. Like Peter, Pope Augustine engages in a secular occupation to help support himself for now. Like Peter in his time, Pope Augustine is hardly known to the world.
I'd LOVE to know what this man does for a living. Wouldn't it be funny if he worked at Wal-mart, a gas station, or something like that. It would be even funnier if he worked at a high-end occupation like an investment firm: "You don't understand, sir, I KNOW this stock is going to do well. It was divinely revealed to me while I was eating my Wheaties this morning."
Same with his "lay clothes" -- I can see it now: "The pope wears Levis", "The pope shops at Sears", etc. Whatever mainstream brand of clothing he wears, it would be funny to think of a pope wearing it.
