I believe this is a nonsense statement. First of all, you don’t define what the “the spirit of Vatican II” is or how it led to a decline in the priesthood. Secondly, you completely ignore any other possible explanations, such as the revolutionary cultural and social changes which took place in Western societies following the close of World War II, the expansion of opportunities for young men hailing from immigrant communities which had long served as a breeding ground for priestly vocations, the social emphasis on a new way of relating between men and women in society, and a newer willingness to question religion and its values during the midpoint of the 20th Century. There could be a whole number of reasons other than the 2nd Vatican Council for the decline in priestly vocations. Pointing to one undefined reason for this decline is barely honest.
