 The cross. What is the essence of the cross? I've shared this story many times and it won't stop me from sharing again today. I was saying mass in a church that not only did not have screens on the windows, it didn't even have windows on the windows. Very poor parish in uptown in Chicago. And I was just saying mass privately. I hadn't been on the calendar on the schedule for that day. And so I was on a hot summer afternoon. I was saying mass and the fruit flies are dive bombing the chalice.
