He felt that it was his duty to have in his Episcopal city a community of Religious men who by their example should assist both clergy and laity in their spiritual life. He did this by building, at his own expense, in 1620, a Capuchin Monastery.
For a long time he supplied these Friars with all that they needed, and finally gave them his own library, which was both choice and extensive.
He was equally cordial in his relationship with other Orders, welcoming them gladly to his own house, and often making retreats in their Monasteries.
Camus was too intimately connected with Francis de Sales not to have with him a community of spirit.
Knowing how useful the newly-formed Order of the Visitation would be to the Church, he also founded at Belley, in 1662, a Convent, to which he invited some nuns of the New Congregation. This Institution of the holy Bishop of Geneva was vigorously attacked from its very beginning. It was called in derision, the Confraternity of the Descent from the Cross, because its pious founder had excluded from this order corporal austerities, and had adapted all his rules to the reforming of the interior. The Bishop of Belley declared himself champion of this new Institution. Indeed, his ardent soul was always on fire to proclaim and to maintain the glory of the Church. At whatever point She was attacked or threatened there Camus was to be found armed cap-a-pie to defend her.
As for his own temporal interests, they were to him matters of absolute indifference when weighed in the balance of that beloved Church. His own words, however, speak best on this subject.
On one occasion, when a Minister of State wrote to ask him something contrary to those interests, backing up his request with the most liberal promises, the Bishop of Belley, after courteously excusing himself from complying with the request, wound up his answer to the statesman with these remarkable words: This is all that can be said to you by a Bishop who, as regards the past, is under no obligation to anyone; as regards the present without interest; and as regards the future has no pretentions whatever.
We have said that the Bishop of Belley was indefatigable in labouring for the sanctification of his people, but this did not in any way prevent him from bestowing due care upon the interests of his own soul.
With this object in view he considered that after long years of toil for his flock he ought to retire from the world, so as to have more time to devote to himself. To live in solitude had been the desire of his youth, as we know it was ever his desire through all the period of his Episcopate; but his spiritual guide, the holy Bishop of Geneva, always succeeded in dissuading him from laying down the pastoral staff to take refuge in the cloister.
However, after the death of his illustrious friend and counsellor, this desire returned to Camus with redoubled force. For seven years, out of respect for the advice of his dear dead friend, he abstained from carrying out his purpose, and during that time of waiting, relaxing nothing in the ardour of his love for his people and his zeal for the Church, he devoted himself to the work of repairing and restoring his Cathedral, which was accomplished in the year 1627.
