Shrine of St. John Neumann and the nearby Shrine of Our Lady of Czestochowa in Doylestown, a northern suburb (where I lived for several years as a teenager).
If you've never read St. John Neumann's short autobiography, I recommend it.
He was so humble I have no doubt he would never have written it except under obedience. It's rather Spartan, but that makes it all the more charming (and the editors provide much additional information). What Neumann doesn't describe are his heroic efforts to minister to his flock. In his various assignments his parishes covered hundreds of miles. Often he would walk twenty miles to visit a sick or dying parishioner to bring the comfort of the sacraments. When farmers loaned him a horse to make travel easier, he was chagrined because he hated riding. Once when he was traveling by foot, he was attacked by robbers and rescued by some friendly braves from a local tribe. Reading about his life makes it clear why he died before he was fifty. He burned himself out like a candle.
As bishop of Philadelphia, Neumann opened over a hundred schools and created many new parishes. He lived simply, wore a threadbare cassock, and when he collapsed on a Philadelphia street one winter evening his rescuers did not immediately recognize as the city's bishop the "beggar" whom they took into a nearby house. The stoop where he stopped to rest before he died is preserved at the shrine as is his body in a glass casket under the altar.
St. John Neumann, pray for us.
