Pre-Tribulation Rapture: The faithful will be caught up prior to the tribulation depicted in Revelation. This is the popular view held by the “Left Behind” crowd.
Mid-Tribulation Rapture: At some point during the tribulation (perhaps 3.5 years through the 7 year ordeal), the faithful are caught up.
Post-Tribulation Rapture: This one should be obvious now.
If one had to classify the Church’s position on the end times, She is post-tribulation.
“But the day of the Lord will come like a thief, and then the heavens will pass away with a mighty roar and the elements will be dissolved by fire, and the earth and everything done on it will be found out. Since all these things are thus to be dissolved, what sort of persons ought you to be in lives of holiness and godliness, waiting for and hastening the coming of the day of God, because of which the heavens will be kindled and dissolved, and the elements will melt with fire! But according to his promise we wait for new heavens and a new earth in which righteousness dwells. Therefore, beloved, since you wait for these, be zealous to be found by him without spot or blemish, and at peace” (2 Peter 3:10‚Äì14).
