After the Manchild [believed to be the church, not Christ only] is caught up [raptured], the Woman flees into the wilderness. Then the Dragon goes to make war with "the remnant of her seed, which keep the commandments of God, and the testimonies of Jesus Christ." Revelation 12:17

........................................"remnant of her seed" suggests that a large number of her seed have already been removed, not just one person, which it would be, if this referred only to Christ.

...............The fact is that the Manchild is a group of people. When they are raptured to heaven, a remnant of her seed is left [a few are remaining]. The ascension of Christ isn't the main fulfillment of the Rapture of the Manchild.
