We dont need to look any further into the preterist system, its Just another false teaching, that denies the very basic scripture to keep itself alive.
Yes the father of your system is the Roman Catholic Jesuit ( Luis De Alcasar 1613), a corrupt foundation, in the "Counter Reformation"
Preterism/historicism pre-dates Alcasar by well over 1000 years.
160AD Clement of Alexandria (On Matthew 24:3,34) "But our Master did not prophesy after this fashion; but, as I have already said, being a prophet by an inborn and every-flowing Spirit, and knowing all things at all times, He confidently set forth, plainly as I said before, sufferings, places, appointed times, manners, limits. Accordingly, therdore, prophesying concerning the temple, He said: "See ye these buildings? Verily I say to you, There shall not be left here one stone upon another which shall not be taken away [Matt. 24:3]; and this generation shall not pass until the destruction begin [Matt. 24:34]. . . ." And in like manner He spoke in plain words the things that were straightway to happen, which we can now see with our eyes, in order that the accomplishment might be among those to whom the word was spoken. (Clementine Homilia, 3:15. See Roberts and Donaldson, Ante-Nicene Fathers, 8:241.)
160AD Tertullian Chap. Viii.--Of The Times Of Christ's Birth And Passion, And Of Jerusalem's Destruction. "Accordingly the times must be inquired into of the predicted and future nativity of the Christ, and of His passion, and of the extermination of the city of Jerusalem, that is, its devastation. For Daniel says, that "both the holy city and the holy place are exterminated together with the coming Leader, and that the pinnacle is destroyed unto ruin."(7) And so the times of the coming Christ, the Leader,(8) must be inquired into, which we shall trace in Daniel; and, after computing them, shall prove Him to be come, even on the ground of the times prescribed, and of competent signs and operations of His. Which matters we prove, again, on the ground of the consequences which were ever announced as to follow His advent; in order that we may believe all to have been as well fulfilled as foreseen. ... "Therefore, when these times also were completed, and the Jews subdued, there afterwards ceased in that place "libations and sacrifices," which thenceforward have not been able to be in that place celebrated; for "the unction," too,(6) was "exterminated" in that place after the passion of Christ. (Against the Jews, Ch.8) (On the Significance of A.D. 70)
200AD Hippolytus of Rome (On the Significance of A.D.70) 30. Are not these things come to pass? Are not the things announced by thee fulfilled? Is not their country, Judea, desolate? Is not the holy place burned with fire? Are not their walls cast down? Are not their cities destroyed? Their land, do not strangers devour it? Do not the Romans rule the country? And indeed these impious people hated thee, and did saw thee asunder, and they crucified Christ. Thou art dead in the world, but thou livest in Christ." (Fragments of Dogmatic and Historical Works, 30)
250AD Lactantius For after a short time the Emperor Vespasian subdued the Jews, and laid waste their lands with the sword and fire, besieged and reduced them by famine, overthrew Jerusalem, led the captives in triumph, and prohibited the others who were left from ever returning to their native land. And these things were done by God on account of that crucifixion of Christ, as He before declared this to Solomon in their Scriptures, saying, "And Israel shall be for perdition and a reproach to the people, and this house shall be desolate; and every one that shall pass by shall be astonished, and shall say, Why hath God done these evils to this land, and to this house? And they shall say, Because they forsook the Lord their God, and persecuted their. King, who was dearly beloved by God, and crucified Him with great degradation, therefore hath God brought upon them these evils." For what would they not deserve who put to death their Lord, who had come for their salvation? (Lactantius: EPITOME OF THE DIVINE INSTITUTES, Ch. 46)
