Scripture is the bulwark of the Church

St. Jerome again most truly says: “A man who is well grounded in the testimonies of the Scripture is the bulwark of the Church.” And if we come to morality and discipline, an apostolic man finds in the sacred writings abundant and excellent assistance; most holy precepts, gentle and strong exhortation, splendid examples of every virtue, and finally the promise of eternal reward and the threat of eternal punishment, uttered in terms of solemn import, in God’s name and in God’s own words.

And it is this peculiar and singular power of Holy Scripture, arising from the inspiration of the Holy Ghost, which gives authority to the sacred orator, fills him with apostolic liberty of speech, and communicates force and power to his eloquence. For those who infuse into their efforts the spirit and strength of the Word of God, speak “not in word only but in power also, and in the Holy Ghost, and in much fulness.” Hence those preachers are foolish and improvident who, in speaking of religion and proclaiming the things of God, use no words but those of human science and human prudence, trusting to their own reasonings rather than to those of God. Their discourses may be brilliant and fine, but they must be feeble and they must be cold, for they are without the fire of the utterance of God and they must fall far short of that mighty power which the speech of God possesses: “for the Word of God is living and effectual, and more piercing than any two-edged sword; and reaching unto the division of the soul and the spirit.” But, indeed, all those who have a right to speak are agreed that there is in the Holy Scripture an eloquence that is wonderfully varied and rich, and worthy of great themes. This St. Augustine thoroughly understood and has abundantly set forth. This also is confirmed by the best preachers of all ages, who have gratefully acknowledged that they owed their repute chiefly to the assiduous use of the Bible, and to devout meditation on its pages.

The Holy Fathers well knew all this by practical experience, and they never cease to extol the sacred Scripture and its fruits. In innumerable passages of their writings we find them applying to it such phrases as “an inexhaustible treasury of heavenly doctrine,” or “an overflowing fountain of salvation,” or putting it before us as fertile pastures and beautiful gardens in which the flock of the Lord is marvelously refreshed and delighted. Let us listen to the words of St. Jerome, in his Epistle to Nepotian: “Often read the divine Scriptures; yea, let holy reading be always in thy hand; study that which thou thyself must preach. . . Let the speech of the priest be ever seasoned with Scriptural reading.” – from Providentissiumus Deus (1893)
