Early in May he reached Nyon, having travelled under the care of his brother from Montpellier. He was received by the members of his family with the utmost affection and respect. One of the most important letters which he wrote during his absence from England was addressed to "The Rev. Messrs. John and Charles Wesley." It is dated from Macon in Burgundy, May 17th, 1778. The following extracts will show Fletcher's judgment concerning the state of morals and religion in France ten years before the Revolution: "Gambling and dress, sinful pleasure and love of money, unbelief and false philosophy, lightness of spirit, fear of man, and love of the world, are the principal sins by which Satan binds his captives in these parts. Materialism is not rare; deism and Socinianism are very common; and a set of freethinkers, great admirers of Voltaire and Rousseau, Bayle and Mirabeau, seem bent upon destroying Christianity and government. If we believe them, the world is the dupe of kings and priests; religion is fanaticism and superstition; subordination is slavery; Christian morality is absurd, unnatural, and impracticable; and Christianity the most bloody religion that ever was. And here it is certain, that by the example of Christians _so called_, and by our continual disputes, they have a great advantage, and do the truth immense mischief. _Popery will certainly fall in France, in this or the next century_; and I have no doubt God will use those vain men to bring about a reformation here, as he used Henry the Eighth to do that work in England; so the madness of His enemies shall, at last, turn to His praise, and to the furtherance of His kingdom.... "If you ask, what system these men adopt, I answer, Some build on deism a morality founded on _self-preservation_, _self-interest_, and _self-honour_; others laugh at all morality, except that which being neglected _violently_ disturbs society. And external order is the decent covering of fatalism, while materialism is their system. "Oh! dear sirs, let me entreat you, in these dangerous days, to use your wide influence, with unabated zeal, against the scheme of these modern Celsuses, Porphyries, and Julians, by calling all professors to think and speak the same things, to love and embrace one another, and to firmly resist those daring men, many of whom are already in England, headed by the admirers of Mr. Hume and Mr. Hobbes. But it is needless to say this to those who have made, and continue to make, such a stand for vital Christianity, so that I have nothing to do but pray that the Lord may abundantly support and strengthen you, and make you a continued comfort to His enlightened people, loving reprovers of those who mix light with darkness, and a terror to the perverse."
