"What are these few orphans we attend to, these few people we bring the good news to, compared to the millions who are lost and abandoned as sheep without a shepherd? I looked for an answer and I found a complete one in the words of Jesus: 'Ask the Lord of the harvest to send out laborers to gather His harvest'. I concluded then that I had found the secret key to all good works and to the salvation of all souls. The entire Church must formally pray for [vocations] because the purpose of the prayer to gain vocations must concern all the faithful, every Christian who has at heart the good of souls and, in a particular way, the Bishops who are the shepherds of the spiritual flock and to whom souls are entrusted."
—Saint Annibale Maria di Francia
