II. According to the historians of those ages the effects of the rosary sermons of St. Dominic were truly wonderful. In all cities where he preached, the people gathered in great numbers to hear his heaven- inspired words and to pray the rosary with St. Dominic. Sinners were converted, the faithful were strengthened and fortified, and many thousands of those who had been led into heresy opened their hearts again to the true faith and returned to the holy Church. The inspired words of St. Dominic met with such splendid results that, even if the tradition did not tell us so, the miraculous effects of this devotion would prove its heavenly inspiration, and Pius IX, Leo XIII, as many Popes before them, have publicly avowed their belief that St. Dominic received the rosary from our blessed Mother. The promise which Dominic received was fulfilled. Where all other means had failed, the humble prayer of the rosary accomplished the victory over heresy. Thus divine wisdom and infinite power make use of humble things to effect great achievements. Of this the great work of the redemption gives us an example. God made the Cross the instrument of the redemption. The despised Cross, once a shame and disgrace, was raised on the height of Calvary and became the instrument of the redemption for all the world, the fountain of grace, a blessing for time and eternity, the symbol of victory and glory. St. Paul, in his first letter to the Corinthians, writes: "And I, brethren, when I came to you, came not in loftiness of speech or of wisdom, declaring unto you the testimony of Christ. For I judge not myself to know anything among you, but Jesus Christ, and him crucified. And my speech and my preaching was not in the persuasive words of human wisdom, but in the showing of the spirit and power. That your faith might not stand on the wisdom of men, but on the power of God. But we preach Christ crucified, unto the Jews indeed a stumbling block, and unto the Gentiles foolishness: But unto them that are called, both Jews and Greeks, Christ the power of God, and the wisdom of God; for the foolishness of God is wiser than men; but the foolish things of the world hath God chosen, that he may confound the strong. That no flesh should glory in his sight" (I Cor. i and ii). And so did God choose the rosary, this humble prayer, to work such great things, that human effort had not been able to accomplish. What an incentive to put all our trust in God, rather than in our own strength! The devotion of the rosary soon spread from southern France to all other Catholic lands, and all peoples welcomed it with joy and prayed it with great zeal. Rosary societies were formed and approved of by the Popes, and were richly endowed with many indulgences. Ever since there has been no other prayer practised so diligently as the rosary. And often there have been recorded miraculous effects of this devotion, no less miraculous than the conversion of the heretics in the south of France.
