From Catholic Culture:
Lord Jesus Christ, Savior of the world! We humbly beg of Thee to manifest in Thy Church the Spirit Whom Thou didst so abundantly bestow upon Thy Apostles. Call, we pray Thee, very many to Thy priesthood and to the religious life. And may zeal for Thy glory and the salvation of souls inflame those whom Thou hast chosen; may they be saints in Thy likeness, and may Thy Spirit strengthen them. O Jesus, give us priests and religious according to Thine own Heart!
O Mary, Mother of Jesus! Obtain for fervent souls the grace to hear and the courage to follow Thy divine Son in the path of religious perfection.
Queen of Apostles, pray for us. Queen of Virgins, pray for us. — CARDINAL SPELLMAN'S PRAYER BOOK
