I guess that is my fault somehow.
statements in the New Testament that assert the second coming was going to happen in the lifetimes of the New Testament generation.
Those prophecies applied to more than one event. Also do not be confused by the Apostles exhortations to be "prepared" for the Second Coming. Every generation is to be prepared and waiting, for no man (including the Apostles) knows the day or hour. Being prepared was(is) still good counsel.
Were Jesus and the Apostles wrong?
Jesus was never wrong. The Apostles had a learning curve (which greatly accelerated after His Ascension).
Peace be unto you.
What part of the Apostles teaching in scripture includes the learning curve? I’d like to know so that I can disregard what they are saying.
As far as the time statements go, you might want to look at a book called “Preterist Time Statements”. It’s a catalog of more than 350 time statements in the New Testament. Those statements declare that all of these things would be completed in the Apostle’s generation. You might be able to say that a handful of them are improperly applied to such eschatology, but you’ll never escape all 350. The bottom line is that they thought, and taught in scripture, that it was going happen. If it didn’t happen this has some profoundly negative implications for Christianity. But, preterism can credibly point out how each of the eschatological passages was fulfilled in that generation.
