I went to Mass this past Monday. I usually don't get the chance to go to daily Mass but had the chance this time. Anway, the entire Mass took no longer than 35 minutes. It was as if the priest was in a hurry to just get it over with. It was really quite disturbing.
When I was a student at Purdue in 1955, the pastor at the student parish was referred to as "high speed Heilman." He could get through a Sunday Mass with smoke, and Benediction, in 45 minutes. He had two teams of altar boys. While he was reading the Last Gospel, one team would be stripping the altar for Benediction, while the other would be bringing out the Benediction robes and the Monstrance.
I have no idea whether he "cut corners" or not.
