that is just one explanation- there are others that come from actual scriptures that seem to indicate a rapture that have nothing to do with that woman’s dream- (ie that Christians will be spared the ‘wrath of God’ in the end times- as well as other scriptures and sentiments in the bible-
The point is, there is no—zero—evidence of a Rapture doctrine prior to Miss Macdonald’s visions. If it were a Biblical doctrine it would have been discovered in Scripture prior to 1830. But up until that date, the Rapture doctrine is unheard of.
If you disagree, a link would be appreciated. Thank you in advance.
