you can do, as parents, to help the current state of Vocations in the Church today, as enumerated by Fr. Todd Peterson, of New Ulm, Minnesota:
This last weekend I preached my first of 8 weekends on the state of vocations in our Diocese in various parishes/Area Faith Communities. Instead of presenting a message of desperation on our need for priests, I tried to present the present state as one of opportunity for us to reflect on the need for priests to preside at the Eucharist and other sacraments, and that God is calling. In addition, I tried to give practical hints of what parents can do to raise their children in a culture of vocations - an environment in which the notion of a call from God is not only capable of being heard but readily responded to.
