33 Therefore in this also let us follow the example of the Angelic Doctor, who never gave himself to reading or writing without first begging the blessing of God, who modestly confessed that whatever he knew he had acquired not so much by his own study and labor as by the divine gift; and therefore let us all, in humble and united prayer, beseech God to send forth the spirit of knowledge and of understanding to the children of the Church and open their senses for the understanding of wisdom. And that we may receive fuller fruits of the divine goodness, offer up to God the most efficacious patronage of the Blessed Virgin Mary, who is called the seat of wisdom; having at the same time as advocates St. Joseph, the most chaste spouse of the Virgin, and Peter and Paul, the chiefs of the Apostles, whose truth renewed the earth which had fallen under the impure blight of error, filling it with the light of heavenly wisdom.
