suspect that many seminarians are dissuaded (or rejected) in reaction to the predominately homosexual orientation of certain orders in certain countries, e.g., the American Jesuits. But perhaps I am being rigid.
Read the book , “Goodbye, Good Men: How Liberals Brought Corruption into the Catholic Church “ by Michael S Rose, to get an feel for why there is a lack of people stepping up for the vocations.
The book was written in 2002 and things have only gotten worse since then.
I seriously doubt that Pope Francis will thumb through the pages any time soon.
Michael Rose defined the Bergoglio cleric in authority who deprived seminaries of future holy priests.
