Here is one of the more interesting ancient excerpts concerning how some in the early church viewed the scriptures and prophecies about Christ's return. Here is the wiki on Irenaeus.
Against Heresies, book V
Chapter XXV.—The fraud, pride, and tyrannical kingdom of Antichrist, as described by Daniel and Paul.
1. And not only by the particulars already mentioned, but also by means of the events which shall occur in the time of Antichrist is it shown that he, being an apostate and a robber, is anxious to be adored as God; and that, although a mere slave, he wishes himself to be proclaimed as a king. For he (Antichrist) being endued with all the power of the devil, shall come, not as a righteous king, nor as a legitimate king, [i.e., one] in subjection to God, but an impious, unjust, and lawless one; as an apostate, iniquitous and murderous; as a robber, concentrating in himself [all] satanic apostasy, and setting aside idols to persuade [men] that he himself is God, raising up himself as the only idol, having in himself the multifarious errors of the other idols. This he does, in order that they who do [now] worship the devil by means of many abominations, may serve himself by this one idol, of whom the apostle thus speaks in the second Epistle to the Thessalonians: “Unless there shall come a failing away first, and the man of sin shall be revealed, the son of perdition, who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he sitteth in the temple of God, showing himself as if he were God.” The apostle therefore clearly points out his apostasy, and that he is lifted up above all that is called God, or that is worshipped—that is, above every idol —for these are indeed so called by men, but are not [really] gods; and that he will endeavour in a tyrannical manner to set himself forth as God.
2. Moreover, he (the apostle) has also pointed out this which I have shown in many ways, that the temple in Jerusalem was made by the direction of the true God. For the apostle himself, speaking in his own person, distinctly called it the temple of God. Now I have shown in the third book, that no one is termed God by the apostles when speaking for themselves, except Him who truly is God, the Father of our Lord, by whose directions the temple which is at Jerusalem was constructed for those purposes which I have already mentioned; in which [temple] the enemy shall sit, endeavouring to show himself as Christ, as the Lord also declares: “But when ye shall see the abomination of desolation, which has been spoken of by Daniel the prophet, standing in the holy place (let him that readeth understand), then let those who are in Judea flee into the mountains; and he who is upon the house-top, let him not come down to take anything out of his house: for there shall then be great hardship, such as has not been from the beginning of the world until now, nor ever shall be.”
It struck me how similar this seems to some aspects of today's Dispensational/Futurist view--a coming ruler (Antichrist) who will speak against God and say that he is God, persecuting those who follow the true God, who will sit in the temple in Jerusalem say he is God.
Remember, Irenaeus wrote this over 100 years after the Romans destroyed Jerusalem and the temple.
Does this prove that Dispensational/Futurist views of the end times are right? No. But it does say something against those who try to disparage it as something new.
