As a young boy back home, my neighborhood was pretty much all Catholic. We had within a twelve square block area 4 Catholic elementary schools, 4 Churches, two catholic High Schools, one all grade Catholic girls boarding school, one orphanage, four convents for the teaching sisters and one convent of strictly cloistered Poor Claire nuns. The big holidays in those days were St Patricks Day and St. Josephs day, which was a really big one. Priests were universally respected and looked up to as a vital link between Christ and us, the laity. They led procession in honor of the Blessed Virgin and the saints. They stood up for the faith and forced us to do the same. They kept a very tight lid on the neighborhood, and that was not an easy task. Weekly Benedictions and adortaions were held. Novenas were encouraged etc.
Then the breath of spring came through. Processions stopped, adortaion stopped benedictions stopped, public rosaries stopped people stopped going to Mass, social consciences were raised due to Vietnam etc. The Priests lost control of the parishes to committees. The sisters left the convents, stopped teaching and started doing all manner of other things.
I recently went back home. There is now one elementary school,. no high schools, no orphanage, no convents, no boarding school and 2 churches. One offers Mass only on Sundays and the churches share the same two priests. Both priests are in their 70’s and ready to retire. It is anticipated that one of the churches will close this year. Virtually no one goes to mass there anymore.The school is totally secularized and doesn’t even offer religion anymore as only about ten percent of the students are practicing Catholics.
Why the drop in vocations, I don’t really know, but it is all tied to the bigger picture I just gave. Multiply my scenario by a thousand all across the country, and I think you have the answer.
