I recently read Michael Svigel's book "The Fathers on the Future" which shows that several early church Fathers were futurists, and especially Irenaeus.
Svigel discusses a statement by Irenaeus that he believes supports a pre-70th week rapture (Svigel is a pre-70th week rapturist, that is "pretrib").
“When in the end the Church shall be suddenly caught up from this, it is said, ‘There shall be tribulation such as has not been since the beginning, neither shall be.’ For this is the last contest of the righteous, in which, when they overcome they are crowned with incorruption.” (Against Heresies V, 29, 1)
The statement by Irenaeus seems unclear and maybe contradictory because elsewhere Irenaeus speaks of Christians on earth during the tribulation (pretribs usually identify the whole 70th Week as "the tribulation"), but Svigel seeks to explain this as Irenaeus believed faithful Christians (those "truly" saved) will be caught up before the tribulation, while the unfaithful (professing Christians that are not really saved) are left behind to face the antichrist.
“And the ten horns which thou sawest are ten kings… And they shall lay Babylon waste, and burn her with fire, and shall give their kingdom to the beast, and put the Church to flight. After that they shall be destroyed by the coming of our Lord.” (Against Heresies V, 26, 1)
“…so that when this man comes WE may avoid him, being aware who he is.” (Against Heresies V, 30, 3–4)
“…the resurrection of the just… takes place after the coming of Antichrist, and the destruction of all nations under his rule.” (Against Heresies V, 35, 1)
From "Search Assist"
- Caught Up Statement: Irenaeus wrote, “When in the end the Church shall be suddenly caught up from this, it is said, ‘There shall be tribulation such as has not been since the beginning, neither shall be.’” This statement is frequently referenced by proponents of the pretribulation rapture.
Context of Tribulation: Despite the above statement, Irenaeus also indicated that the Church would face persecution during the tribulation. He described the tribulation as “the last contest of the righteous,” suggesting that believers would endure trials before being rewarded.
