Totally false.
Darby was teaching the rapture *before* MacDonald claimed to have a vision.
Beyond that, the teaching of a rapture predated MacDonald by more tha 1,000 years.

Everything those people said they were talking about the 2nd. Coming, not some sort of Rapture that comes AFTER the verses that talk about the 2nd. Coming; it’s like counting: 12435 - the Rapture happening after the 2nd Coming???
