37 We well know, however, that our united labors will by no means suffice to pluck up these pernicious seeds from the Lord's field, unless the Heavenly Master of the vineyard shall mercifully help us in our endeavours. We must, therefore, with great and anxious care, implore of Him the help which the greatness of the danger and of the need requires. The sect of the Freemasons shows itself insolent and proud of its success, and seems as if it would put no bounds to its pertinacity. Its followers, joined together by a wicked compact and by secret counsels, give help one to another, and excite one another to an audacity for evil things. So vehement an attack demands an equal defence-namely, that all good men should form the widest possible association of action and of prayer. We beseech them, therefore, with united hearts, to stand together and unmoved against the advancing force of the sects; and in mourning and supplication to stretch out their hands to God, praying that the Christian name may flourish and prosper, that the Church may enjoy its needed liberty, that those who have gone astray may return to a right mind, that error at length may give place to truth, and vice to virtue. Let us take our helper and intercessor the Virgin Mary, Mother of God, so that she, who from the moment of her conception overcame Satan may show her power over these evil sects, in which is revived the contumacious spirit of the demon, together with his unsubdued perfidy and deceit. Let us beseech Michael, the prince of the heavenly angels, who drove out the infernal foe; and Joseph, the spouse of the most holy Virgin, and heavenly patron of the Catholic Church; and the great Apostles, Peter and Paul, the fathers and victorious champions of the Christian faith. By their patronage, and by perseverance in united prayer, we hope that God will mercifully and opportunely succor the human race, which is encompassed by so many dangers.
