That is interesting about Irenaeus and his view on the antichrist. I'll go and read up on this. I do know he spoke of the kingdom passages being fulfilled in the New Covenant with Christ.
175: Irenaeus - Against Heresies "the temple constructed of stones was indeed then rebuilt (for as yet that law was observed which had been made upon tables of stone), yet no new covenant was given, but they used the Mosaic law until the coming of the Lord; but from the Lord's advent, the new covenant which brings back peace, and the law which gives life, has gone forth over the whole earth, as the prophets said: "For out of Zion shall go forth the law, and the word of the Lord from Jerusalem ; and He shall rebuke many people; and they shall break down their swords into ploughshares, and their spears into pruninghooks, and they shall no longer learn to fight."
So it is interesting to me that he is still a futurist with the tribulation or antichrist. Thanks for the info. I'll go and read it.
I did see that he speculated that the antichrist 666 and man of sin, or the meaning of 666 would probably be revealed at the fall of rome, because he wasn't sure who it was. He also seems to be a pre mil? is this correct. I'll have some reading to do to catch up on him.
