Secondly, Jesus asked who would give a child a stone when the child asked for bread. These perverts gave countless children stones as payment for the child's trust and safety.
I submit that until the Church, at the highest levels, make a concerted effort to make sure this doesn't happen again, it will continue to be plagued with low vocations.
With the information coming to light about many of the hierarchy advocating abortion and homosexuality, nothing will change.
My theory is that the biggest cause of the lack of vocations is the lack of children. In families with many kids, one could be “spared” for the church.
With the collapse of birthrates and family size there are no “spares”.
All good points, particularly with regard to contraception. Here is a good summary of what hell the blow-back to Humanae Vitae wrought.
