incorrect. there are plenty of non-full preterist scholarly resources that demonstrate the belief “this generation” refers to the destruction of Jerusalem. See below for just a small example. However, as to your position, I cannot find any that agree. Are you able to provide any?
Barnes commentary on Matthew 24:34
“This generation ... - This age; this race of people. A generation is about 30 or 40 years. The destruction of Jerusalem took place about forty years after this was spoken.”
Gills commentary on Matthew 24:34:
“Verily I say unto you, this generation shall not pass,.... Not the generation of men in general; as if the sense was, that mankind should not cease, until the accomplishment of these things; nor the generation, or people of the Jews, who should continue to be a people, until all were fulfilled; nor the generation of Christians; as if the meaning was, that there should be always a set of Christians, or believers in Christ in the world, until all these events came to pass;
but it respects that present age, or generation of men then living in it; and the sense is, that all the men of that age should not die, but some should live
till all these things were fulfilled; see
Matthew 16:28 as many did, and as there is reason to believe they might, and must, since all these things had their accomplishment, in and about forty years after this: and certain it is, that John, one of the disciples of Christ, outlived the time by many years; and, as Dr. Lightfoot observes, many of the Jewish doctors now living, when Christ spoke these words, lived until the city was destroyed; as Rabban Simeon, who perished with it, R. Jochanan ben Zaccai, who outlived it, R. Zadoch, R. Ishmael, and others:
this is a full and clear proof, that not anything that is said before, relates to the second coming of Christ, the day of judgment, and end of the world; but that all belong to the coming of the son of man, in the destruction of Jerusalem, and to the end of the Jewish state.”
expositor Greek testament on Matthew 24:34
“Solemn assurance that the predicted will come to pass.—πάντα ταῦτα is most naturally taken to mean the same things as in
Matthew 24:33, he main subject of the discourse, the impending destruction of the Jewish state. Jesus was quite certain that they would happen within the then living generation (ἡ γενεὰ αὕτη), not merely through miraculous foresight but through clear insight into the moral forces at work”
Bengels gnomen on Matthew 24:34
“From the date of this prediction to the destruction of Jerusalem was a space of forty years, and from the true year of our Lord’s nativity to that event was a space of about seventy-five years. The Jews, however (as, for example, in Seder Olam), reckon seventy-five years as one generation, and the words, οὐ μὴ παρέλθῃ, “shall not pass away,” intimate that the greater part of that generation, but not the whole of it, should have passed away before all the events indicated should have come to pass. The prediction is true with respect to either the forty or the seventy-five years.[1062] So accurately did the Evangelist describe it many years before the event took place.”
Benson commentary on Matthew 24:34:
“This generation shall not pass till all these things be fulfilled, — Hereby evidently showing that he had been speaking all this while only of the calamities coming on the Jews, and the destruction of Jerusalem. “It is to me a wonder,” says Bishop Newton, “how any man can refer part of the foregoing discourse to the destruction of Jerusalem, and part to the end of the world, or any other distant event, when it is said so positively here in the conclusion, All these things shall be fulfilled in this generation.”
