L. the benefits which the Eternal Wisdom had determined to confer upon mankind through revelation, depended, however, on a condition without which, they could never have been realized. It was necessary that men, on their part, should be inclined to receive the bidding addressed to them, that they should direct their attention to the truths to be gradually promulgated to them for their own advantage; in short, that they should feel disposed to correspond to the Divine intentions. It was no part of the plan of the Divine wisdom that men should be in any way constrained, for that would have been depriving them of the precious gift of free will, and destroying their essence. But this very liberty, of action granted to man, rendered the realization of the Divine thought doubtful; and it might have happened that a generation, sinking itself into complete corruption, would have lost every trace of the truths already revealed; and thence a necessity would have arisen for one or more repetitions of the communication, with equal uncertainty of permanent success.

LI. To avoid such a danger, it pleased the Divine Mercy to found upon earth a permanent institution of an exceptional, wonderful, almost preternatural character, through which the preservation of the principal doctrines, that form the substance of revealed religion, could be insured to mankind. As seeds of rare and precious plants are preserved with care, that the species may not perish, so the Ruler of Providence designed to establish among us a repository wherein to keep the germs of all that which concerns man's spiritual life; and He so ordained that they should be there jealously guarded, and with particular diligence cultivated, in order to bring about their slow and gradual, but sure propagation among all the individuals of the human family. This provision is a most luminous proof of the unbounded love and mercy of the Divine Artificer towards the rational creature, to whom a powerful assistance is thus offered to attain his noble destination, without in the least impairing his liberty of action.

LII. Such a provision consists in God having chosen a small portion of mankind to be a medium for, and co-operator in, the grand work, and having entrusted to it the special important mission of perpetually preserving within its pale, the principal dogmas of revealed religion; of keeping always alive on earth the remembrance of that relation which was established from the beginning of creation between the Creator and the human family; and, in short, of contributing with all its might to the practical realization of the Divine idea. The chosen few had consequently to propose to themselves, as the goal of their career, the defence of the sacred deposit entrusted to them from all attacks that might be directed by malice, ignorance or superstition; they had to promote the propagation of the notions of monotheism; of the divine origin of man, and of the duties incumbent upon him to practice justice, charity, rectitude, and piety; they had to protest incessantly against polytheism, and against all and every idolatrous and superstitious creed, as adverse and injurious to the development of the principles of revealed religion; they had to confirm these theories by making themselves the exemplars of a religious life, and by bearing witness to them, when necessary, by their own martyrdom; they had thus to become the effectual instruments to the gradual diffusion throughout the world of those elements of truth, of virtue and happiness, calculated to bring forth the ultimate and universal perfection of mankind.

LIII. In order that the individuals charged with such a grand mission should be competent effectually to fulfil it, it was necessary that they should themselves have been always free from the pernicious influence of the errors and corruption, which had already spread almost throughout the world; it was necessary that their minds should have remained unpolluted by the notions of the extravagant and degrading idolatries, which were in practice among almost all the ancient nations; and that their hearts should have remained untouched by the contagion of universal depravity. The soil to which any seed, however good, is to be committed, would never respond to the expectations of the husbandman, if it were not cleared from weeds and thistles. Those individuals had, therefore, to be drawn aside from the general society of men; and from their infancy educated and prepared, so as to receive within their virgin souls the seeds that were afterwards to produce in them, and through them, the spiritual regeneration of all mankind. But here another difficulty presented itself; who would have undertaken the charge of watching over those individuals from their infancy, and keeping them in such an isolation, as to make them inaccessible to the general depravity? It was, then, necessary to begin by a single individual, whose descendants should receive from that stock the education capable of fitting them for their future mission.

LIV. The providential measure once decreed, of selecting an individual as guardian of the revealed truths, and making him the father of a posterity, whose duty was to preserve them and to make them fructify, it remained only to determine the selection of the person. And here it is obvious that not a capricious hazard, not an indulgent predilection, but only a strict justice and wise impartiality could determine the important choice. Whoever would have aspired to such a glory—and everybody could have aspired to it—by no other means could he have attained it than his own merits. Such a man must have, of his own accord and spontaneously, withdrawn himself from the general current of depravity; opposed, by his own impulse, the absurd ravings of his contemporaries; displayed a lively attachment to virtue, and a steady abhorrence of evil; cultivated, above all, justice, charity, and righteousness, in his every action; that man must have thrown off the subjection of the senses, and all cupidity of earthly things, and, almost assuming a second nature, have soared towards the eternal Source of truth, the Creator of the universe, offering as a sacrifice to Him his own dearest personal interests, and, if required, his life itself.
