In Gulliver's Travels by Jonathan Swift, there is little discussion of religion except for a passage from part 3, which reads,
To this I added another petition, “that for the sake of my patron the king of Luggnagg, his majesty would condescend to excuse my performing the ceremony imposed on my countrymen, of trampling upon the crucifix: because I had been thrown into his kingdom by my misfortunes, without any intention of trading.” When this latter petition was interpreted to the Emperor, he seemed a little surprised; and said, “he believed I was the first of my countrymen who ever made any scruple in this point; and that he began to doubt, whether I was a real Hollander, or not; but rather suspected I must be a Christian.
We never find out if Gulliver is in fact, Christian, but this is the only mention I could find in the book. Do we know whether he was Christian? Does Swift ever mention it in any of his letters?
