In early 1830 Margaret was the very first one to see a pre-Antichrist (pretrib) rapture in the Bible - and John Walvoord and Hal Lindsey lend support for this claim!
Walvoord's "Rapture Question" (1979) says her view resembles the "partial-rapture view" and Lindsey's "The Rapture" (1983) admits that "she definitely teaches a partial rapture."
But there's more. Lindsey (p. 26) says that partial rapturists see only "spiritual" Christians in the rapture and "unspiritual" ones left behind to endure Antichrist's trial. And Walvoord (p. 97) calls partial rapturists "pretribulationists"!
Margaret's pretrib view was a partial rapture form of it since only those "filled with the Spirit" would be raptured before the revealing of the Antichrist. A few critics, who've been repeating more than researching, have noted "Church" in the tribulation section of her account. Since they haven't known that all partial rapturists see "Church" on earth after their pretrib rapture (see above chart), they've wrongly assumed that Margaret was a posttrib!
In Sep. 1830 Edward Irving's journal "The Morning Watch" (hereafter: TMW) was the first to publicly reflect her novel view when it saw spiritual "Philadelphia" raptured before "the great tribulation" and unspiritual "Laodicea" left on earth.
In Dec. 1830 John Darby (the so-called "father of dispensationalism" even though he wasn't first on any crucial aspect of it!) was still defending the historic posttrib rapture view in the "Christian Herald."
Pretrib didn't spring from a "church/Israel" dichotomy, as many have assumed, but sprang from a "church/church" one, as we've seen, and was based only on symbols!
But innate anti-Jewishness soon appeared. (As noted, TMW in Sep. 1830 saw only less worthy church members left behind.) In Sep. 1832 TMW said that less worthy church members and "Jews" would be left behind. But by Mar. 1833 TMW was sure that only "Jews" would face the Antichrist!
As late as 1837 the non-dichotomous Darby saw the church "going in with Him to the marriage, to wit, with Jerusalem and the Jews." And he didn't clearly teach pretrib until 1839. His basis then was the Rev. 12:5 "man child...caught up" symbol he'd "borrowed" (without giving credit) from Irving who had been the first to use it for the same purpose in 1831!
