Bishop Perez has been away from the Delaware Valley for the last seven years but he said, at heart, he's a Philadelphia priest.
Of course, he was ordained in Philadelphia and spent 28 years here.
So when the Vatican called and said he would return as Archbishop he was caught off-guard, especially since he was with Pope Francis just a few weeks prior and Francis gave him no indication about the major appointment that was in store.
"Did you think you would be returning to Philadelphia did you see this coming?" Sharrie asked.
"Absolutely not. God is a God of surprises and this is a surprise I never saw in my wildest imagination," said Perez.
