In another letter, written from Aix, he says: "Soon after our arrival here, I rode out most days with my dear and valued friend. Now and then he complained of the uneasiness of the horse, and there were some remains of soreness in his breast, but this soon went off. The beginning of February was warm, and the warmth, when he walked in the fields, relaxed him; but when the wind got north or east, he was braced again. His appetite is good, his complexion as healthy as it was eleven years ago. As his strength increases he increases the length of his rides. Last Tuesday he set out on a journey of a hundred and twelve miles. The first day he travelled forty miles without feeling any fatigue, and the third day fifty-five. He bore the journey as well as I did, and was as well and as active at the end of it as at the beginning. During the day he cried out, 'Help me to praise the Lord for His goodness; I never expected to see this day.' He accepted a pressing invitation to preach to the Protestants here; and he fulfilled his engagement on Sunday morning, taking as his text, 'Examine yourselves, whether ye be in the faith.' Both the French and English were greatly affected; the word went to the hearts of both saints and sinners. His voice is now as good as ever it was, and he has an earnest invitation to preach near Montpellier, where we are going. You would be astonished at the entreaties of pastors as well as people. He has received a letter from a minister in the Levine Mountains, who intends to come to Montpellier, sixty miles, to press him to go and preach to his flock. He purposes to spend the next summer in his own country, and the following winter in these parts."
From Montpellier Fletcher wrote to his curate, Mr. Greaves: "Please God, I shall set out next week from this place, where the winter has been uncommonly rainy and windy. We had over half an inch of snow last week, but it was gone long before noon. The climate has, nevertheless, agreed with me better than England, and as a proof of it, I need only tell you that I rode last Friday from Hyères, the orange gardens of France, hither, which is near fifty miles, and was well enough to preach last Sunday, in French, at the Protestant chapel.... At the first convenient opportunity, please to read the following note in the church: John Fletcher sends his best Christian love to the congregation that worships God in the parish church at Madeley. He begs the continuance of their prayers for strength of body and mind, that he may be able (if it be the will of God) to serve them again in the gospel. He desires them to return Almighty God thanks for having enabled him to speak again in public last Sunday, without having had a return of his spitting of blood, which he considers as a token that his life may be spared a little, to exhort them to grow in grace, in the knowledge of our Lord Jesus Christ, and in brotherly love;—the best marks that we know God, and are in the faith of Christ."
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."
While residing at Nyon Fletcher was visited by his friend and former medical adviser, William Perronet, son of the venerable Vicar of Shoreham. The Perronet family was of Swiss origin, and about this time it came to the knowledge of Mr. Perronet that he had some claim to a property situated at Chateau d'Œx, a small town in a mountain valley, about twenty miles from the north-eastern shore of the Lake of Geneva, and nearly sixty from Nyon. Fletcher assisted his friends by making inquiries and obtaining legal advice, and it was thought necessary that William Perronet should go over to press the claim in person. This he accordingly did, and, it may be said here, with complete success, though he did not live to enjoy the possession, as he was taken ill on his way home, and died before reaching England.
Fletcher wrote, inviting him to be his guest: "This is a delightful country. If you come to see it, and to claim the estate, bring all the papers and letters you can collect; and share a pleasant apartment, and one of the finest prospects in the world, in the house where I was born."
