But that's not the "oldest Christian commentary", is it? The oldest is Mt 24, where Jesus comments on the AofD and says it/he is to happen in Judea to that listening/seeing generation to which those listening to him must make direct response and get out of Jerusalem. The AofD would be in the temple, mess up Israel, and lead to its collapse for no good reason.
It is extremely odd to me, that, with all the tools at his disposal to "protect" the Pope from Reformation accusations, the Jesuit Ribera used these remarks by Irenaeus to construct a view of the future in 1560, which then show up in Protestantism a couple hundred years later, but nowhere else that I know of in between (nor did he!). Ie, when the Catholic scholar "really" hit the books, he couldn't see justification by faith, but he could see a future 70th week! Meanwhile, in the land where historical-grammatical interp had a rebirth, it was so widely understood that Mt 24 & //s had to do with the awful events of the 7th decade in Judea, that major works of art were commissioned to depict it. How could this happen?
