He was plunged in these noble studies, when two terrible blows fell upon him; he learned of the successive deaths of his two eldest brothers, who had fallen gloriously, one at Freiburg, the other at Nördlingen. He became thus the head of the family, and as if the temptations which this title offered him were not sufficient, bringing him as it did, together with a great name a brilliant future, his mother came, supported by the Bishop of Evreux, his cousin, to beg him to abandon the ecclesiastical career and to marry, in order to maintain the honour of his house. Many others would have succumbed, but what were temporal advantages to a man who had long aspired to the glory of going to preach the Divine Word in far-off missions? He remained inflexible; all that his mother could obtain from him was his consent to devote to her for some time his clear judgment and intellect in setting in order the affairs of his family. A few months sufficed for success in this task. In order to place an impassable abyss between himself and the world, he made a full and complete renunciation in favour of his brother Jean-Louis of his rights of primogeniture and all his titles to the seigniory of Montigny and Montbeaudry. The world is ever prone to admire a chivalrous action, and to look askance at deeds which appear to savour of fanaticism. To Laval this renunciation of worldly wealth and honour appeared in the simple light of duty. His Master's words were inspiration enough: "Wist ye not that I must be about my Father's business?"

Returning to the Collège de Clermont, he now thought of nothing but of preparing to receive worthily the holy orders. It was on September 23rd, 1647, at Paris, that he saw dawn for him the beautiful day of the first mass, whose memory perfumes the whole life of the priest. We may guess with what fervour he must have ascended the steps of the holy altar; if up to that moment he had merely loved his God, he must on that day have dedicated to Jesus all the powers of his being, all the tenderness of his soul, and his every heart-beat.

Mgr. de Péricard, Bishop of Evreux, was not present at the ordination of his cousin; death had taken him away, but before expiring, besides expressing his regret to the new priest for having tried at the time, thinking to further the aims of God, to dissuade him from the ecclesiastical life, he gave him a last proof of his affection by appointing him archdeacon of his cathedral. The duties of the archdeaconry of Evreux, comprising, as it did, nearly one hundred and sixty parishes, were particularly heavy, yet the young priest fulfilled them for seven years, and M. de la Colombière explains to us how he acquitted himself of them: "The regularity of his visits, the fervour of his enthusiasm, the improvement and the good order which he established in the parishes, the relief of the poor, his interest in all sorts of charity, none of which escaped his notice: all this showed well that without being a bishop he had the ability and merit of one, and that there was no service which the Church might not expect from so great a subject."

But our future Bishop of New France aspired to more glorious fields. One of those zealous apostles who were evangelizing India at this period, Father Alexander of Rhodes, asked from the sovereign pontiff the appointment for Asia of three French bishops, and submitted to the Holy See the names of MM. Pallu, Picquet and Laval. There was no question of hesitation. All three set out immediately for Rome. They remained there fifteen months; the opposition of the Portuguese court caused the failure of this plan, and François de Laval returned to France. He had resigned the office of archdeacon the year before, 1653, in favour of a man of tried virtue, who had been, nevertheless, a prey to calumny and persecution, the Abbé Henri-Marie Boudon; thus freed from all responsibility, Laval could satisfy his desire of preparing himself by prayer for the designs which God might have for him.

In his desire of attaining the greatest possible perfection, he betook himself to Caen, to the religious retreat of M. de Bernières. St. Vincent de Paul, who had trained M. Olier, was desirous also that his pupil, before going to find a field for his apostolic zeal among the people of Auvergne, should prepare himself by earnest meditation in retirement at St. Lazare. "Silence and introspection seemed to St. Vincent," says M. de Lanjuère, the author of the life of M. Olier, "the first conditions of success, preceding any serious enterprise. He had not learned this from Pythagoras or the Greek philosophers, who were, indeed, so careful to prescribe for their disciples a long period of meditation before initiation into their systems, nor even from the experience of all superior men, who, in order to ripen a great plan or to evolve a great thought, have always felt the need of isolation in the nobler acceptance of the word; but he had this maxim from the very example of the Saviour, who, before the temptation and before the transfiguration, withdrew from the world in order to contemplate, and who prayed in Gethsemane before His death on the cross, and who often led His disciples into solitude to rest, and to listen to His most precious communications."

In this little town of Caen, in a house called the Hermitage, lived Jean de Bernières of Louvigny, together with some of his friends. They had gathered together for the purpose of aiding each other in mutual sanctification; they practised prayer, and lived in the exercise of the highest piety and charity. François de Laval passed three years in this Hermitage, and his wisdom was already so highly appreciated, that during the period of his stay he was entrusted with two important missions, whose successful issue attracted attention to him and led naturally to his appointment to the bishopric of Canada.

As early as 1647 the king foresaw the coming creation of a bishopric in New France, for he constituted the Upper Council "of the Governor of Quebec, the Governor of Montreal and the Superior of the Jesuits, until there should be a bishop." A few years later, in 1656, the Company of Montreal obtained from M. Olier, the pious founder of the Seminary of St. Sulpice, the services of four of his priests for the colony, under the direction of one of them, M. de Queylus, Abbé de Loc-Dieu, whose brilliant qualities, as well as the noble use which he made of his great fortune, marked him out naturally as the probable choice of his associates for the episcopacy. But the Jesuits, in possession of all the missions of New France, had their word to say, especially since the mitre had been offered by the queen regent, Anne of Austria, to one of their number, Father Lejeune, who had not, however, been able to accept, their rules forbidding it. They had then proposed to the court of France and the court of Rome the name of François de Laval; but believing that the colony was not ready for the erection of a see, they expressed the opinion that the sending of an apostolic vicar with the functions and powers of a bishop in partibus would suffice. Moreover, if the person sent should not succeed, he could at any time be recalled, which could not be done in the case of a bishop. Alexander VII had given his consent to this new plan, and Mgr. de Laval was consecrated by the nuncio of the Pope at Paris, on Sunday, December 8th, 1658, in the church of St. Germain-des-Prés. After having taken, with the assent of the sovereign pontiff, the oath of fidelity to the king, the new Bishop of Petræa said farewell to his pious mother (who died in that same year) and embarked at La Rochelle in the month of April, 1659. The only property he retained was an income of a thousand francs assured to him by the Queen-Mother; but he was setting out to conquer treasures very different from those coveted by the Spanish adventurers who sailed to Mexico and Peru. He arrived on June 16th at Quebec, with letters from the king which enjoined upon all the recognition of Mgr. de Laval of Petræa as being authorized to exercise episcopal functions in the colony without prejudice to the rights of the Archbishop of Rouen.

Unfortunately, men's minds were not very certain then as to the title and qualities of an apostolic vicar. They asked themselves if he were not a simple delegate whose authority did not conflict with the jurisdiction of the two grand vicars of the Jesuits and the Sulpicians. The communities, at first divided on this point, submitted on the receipt of new letters from the king, which commanded the recognition of the sole authority of the Bishop of Petræa. The two grand vicars obeyed, and M. de Queylus came to Quebec, where he preached the sermon on St. Augustine's Day (August 28th), and satisfied the claim to authority of the apostolic vicar.

But a new complication arose: the St. André, which had arrived on September 7th, brought to the Abbé de Queylus a new appointment as grand vicar from the Archbishop of Rouen, which contained his protests at court against the apostolic vicar, and letters from the king which seemed to confirm them. Doubt as to the authenticity of the powers of Mgr. de Laval might thus, at least, seem permissible; no act of the Abbé de Queylus, however, indicates that it was openly manifested, and the very next month the abbé returned to France.

We may understand, however, that Mgr. de Laval, in the midst of such difficulties, felt the need of early asserting his authority. He promulgated an order enjoining upon all the secular ecclesiastics of the country the disavowal of all foreign jurisdictions and the recognition of his alone, and commanded them to sign this regulation in evidence of their submission. All signed it, including the devoted priests of St. Sulpice at Montreal.
