To Dr. Brown SIR, Since I had the pleasure of waiting upon you, I have been often reflecting on the account given us of the Indians in Paraguay. It is about four and twenty years since I read the first account of them, translated from a French author. It then made much the same impression on my mind, which I believe it has now made on yours. Permit me, Sir, to speak my free thoughts concerning it, which I shall be glad to alter, upon better information. I am throughly persuaded that true, genuine religion is capable of working all those happy effects which are said to be wrought there; and that, in the most ignorant and savage of the human-kind. I have seen instances of this: no Indians are more savage than were the colliers of Kingswood; many of whom are now an humane, hospitable people full of love to God and man; quiet, diligent in business; in every state content; every way adorning the Gospel of God their Saviour.

But the difficulty with me lies here. I am not persuaded, that the Romish Missionaries (very few excepted) either know, or teach, true, genuine religion. And of all their Missionaries, generally speaking, the Jesuits are the worst. They teach nothing less than the true genuine religion of Jesus Christ. They spend their main strength in teaching their converts, so called, the opinions and usages of their Church. Perhaps the most religious that ever was among them, was their 'East Indian Apostle,' Francis Xavier. And from his own Letters (four volumes of which I had) it plainly appears, that (whether he knew it himself or no) he never taught one tittle of the religion of the heart, but barely opinions and externals. Now what virtue, what happiness can possibly spring from such a root as this Allowing then, that the Paraguay converts have peace and plenty, allowing they have moral honesty, allowing they have an outward form of religion (and thus far I know not but their guides may bring them), I cannot believe they have gone one step farther, or that they know what True Religion is. Do their instructors experience the inward Kingdom of God Righteousness and peace and joy in the Holy Ghost And if not, are they likely to lead others, any farther than they have gone themselves Can they point out The Eternal Sunshine of the spotless Mind, Each Prayer accepted, and each Wish resigned 7 Desires composed, Affections ever even; Tears that delight, and Sighs that waft to Heaven Pope, Eloisa and Abelard, p. 207, quoted in Earnest Appeal, 3. And without this, who can be happy Who can avoid feeling many dull, heavy hours Let the Indians eat, drink, dance, play: all this will not fill up the blanks of life. Their highest enjoyments will carry them no farther than 'Sauntring Jack and Idle Joan' An Epitaph, 1. 2: 'Without love, hatred, joy, or fear, They led-a kind of-as it were.' in Prior. What can carry them any farther but heart-religion, 'Fellowship with the Father and with the Son'! O may you and yours always experience this better part, which alone takes away the weariness of life, which alone gives that heart-felt, that unceasing joy, the pledge and earnest of Life Eternal! I am, sir, Your very humble servant.
