Mystici Corporis Christi §101
Mystici Corporis Christi: On the Mystical Body of Christ
101 After the example of Christ we too should pray daily to the Lord of the harvest to send laborers into His harvest. Our united prayer should rise daily to heaven for all the members of the Mystical Body of Jesus Christ; first for Bishops who are responsible in a special way for their respective dioceses; then for priests and religious, both men and women, who have been called to the service of God, and who, at home and in the foreign missions, are protecting, increasing, and advancing the Kingdom of the Divine Redeemer. No member of this venerated Body must be forgotten in this common prayer; and let there be a special remembrance of those who are weighed down with the sorrows and afflictions of this earthly exile, as also for the suffering souls in Purgatory. Neither must those be neglected who are being instructed in Christian doctrine, so that they may be able to receive baptism without delay.
