O God, Who wills not the death of a sinner but rather that he be converted and live, grant we beseech you, through the intercession of the Blessed Mary, ever Virgin, Saint Joseph, her spouse, St. Junipero Serra, and all the saints, an increase of laborers for your Church, fellow laborers with Christ to spend and consume themselves for souls, through the same Jesus Christ, Your Son, Who lives and reigns with You in the unity of the Holy Spirit, God forever and ever. Amen.
O God, You have constituted Your only-begotten Son supreme and eternal Priest for the glory of Your majesty and the salvation of mankind: grant that those whom He has chosen ministers and dispensers of His mysteries may be found faithful in fulfilling the ministry they have received.
Serra also encourages these prayers for the rosary:
O Lord, I offer You this rosary for the increase in vocations to the priesthood, religious life and the permanent diaconate and for a strengthening of all current vocations, lay or religious. O Jesus, may Your Mother Mary watch over and protect all young men and women considering a vocational call to priestly or religious life.
God our Father, please send us Holy Priests. All for the sacred and Eucharistic heart of Jesus; all for the immaculate and sorrowful heart of Mary; in union with St. Joseph. Amen.
O God, grant that my son/daughter, N., may become a priest/religious. I myself want to live as a good Christian and want to guide my child always to do what is right, so that I may receive the grace, O God, to be allowed to give you a holy priest/religious. Amen.
