Very interesting graphic. What do you suppose changed that caused the increase, and then the decrease?
The orthodoxy of the Bishops — first
Second — the visitations and recommendations to seminaries
Third — the almost horrendous screening that goes on for entrance into the seminary, two day oral pschye examination, written opus about becoming a priest, interviews by several faculty members and the vocations director at the seminary. It all takes about six months. Can you imagine examinations like that for any other career/vocation in life?
