" It may come as a surprise to many Christians, but the doctrine of the Rapture is not mentioned in any Christian writings, of which we have knowledge, until after the year 1830 A.D. Whether the early writers were Greek or Latin, Armenian or Coptic, Syrian or Ethiopian, English or German, orthodox or heretic, no one mentioned a syllable about it. Of course, those who feel the origin of the teaching is in the Bible would say that it only ceased being taught (for some unknown reason) at the close of the apostolic age only to reappear in 1830 A.D. But if the doctrine were so clearly stated in Scripture, it seems incredible that no one should have referred to it before the 19th century. This does not necessarily show that the teaching is wrong, but it does mean that thousands of eminent scholars who lived over a span of seventeen centuries (including some of the most astute of the "Christian Fathers" and those of the Reformation and post-Reformation periods) must be considered as prophetic dunces for not having understood so fundamental a teaching.
