Could it be that the local preterist is trying to correct the Christian Zionist, but he does not see prophecies in the New Testament predicting such a falling away from sound doctrine after the time of the Capital C Roman Catholic Church's apostasy?
Some of these prophecies about a later falling away of the Capital C Church, which in I Peter 5: 3 acts "as being lords over God's heritage," rather than "being ensamples to the flock," are in I and II Timothy.
I Timothy 4: 1-2 says "Now the Spirit speaketh expressly, that in the
latter times some shall depart from the faith, giving heed to seducing
spirits, and doctrines of devils;
2.Speaking lies in hypocrisy; having their conscience seared with a
hot iron;"
II Timothy 4: 3-4 says "For the time will come when they will not
endure sound doctrine; but after their own lusts shall they heap to
themselves teachers, having itching ears;
4.And they shall turn away their ears from the truth, and shall be
turned unto fables."
II Timothy 3: 1- 8: "This know also, that in the last days perilous times shall come.
2. For men shall be lovers of their own selves, covetous, boasters, proud, blasphemers, disobedient to parents, unthankful, unholy,
3. Without natural affection, trucebreakers, false accusers, incontinent, fierce, despisers of those that are good,
4. Traitors, heady, highminded, lovers of pleasures more than lovers of God;
5.
6. For of this sort are they which creep into houses, and lead captive silly women laden with sins, led away with divers lusts,
7. Ever learning, and never able to come to the knowledge of the truth.
8. Now as Jannes and Jambres withstood Moses, so do these also resist the truth: men of corrupt minds, reprobate concerning the faith."
II Timothy 3: 1-8 has verses that describe the personality traits of people in the Counterculture and larger Me Generation. Social scientists Hendin,
Lasch and Yankelovich said that people in the Counterculture show a great
deal of self-peoccupation. They also place much importance on
attaining self-esteem. See: Herbert Hendin. The Age of Sensation, 1975, Christopher Lasch. The Culture of Narcissism: American Life In An Age of Diminishing Expectations, 1978, and Daniel Yankelovich. New Rules: Searching for Self-Fulfillment In A World Turned Upside Down, 1981. In fact, the Me Generation, those in it who read Carl Rogers and A.H. Maslow or heard about their ideas were influenced back then by Rogerian self psychology and a somewhat similar self psychology of Maslow.
In the Counterculture and in the Me Generation which followed, there are at least four major shifts in the culture or paradigm, resulting in some changes in personality traits:
1. An Increase in Selfishness and Self-Preoccupation.
2. The Revolt Against Christianity, Especially Opposing Christian Morality
3. The Reduction of the Human To Desire, Feeling and Conditioning,
that is the "killing" of any development of man's third part, which is
his spirit, developed in him by the Holy Spirit..
4. The Denial of what George Orwell Called Objective Reality. The New Anti-
Culture of Transformational Marxism not only allows
for the telling of lies in certain circumstances. As a culture, it
also teaches that there may be no agreed upon reality outside your
individual mind against which your statements can be checked to see if
you are telling lies or not. In the drug movement the idea that one
creates his own reality was taught by Tim Leary, Ken Kesey, Richard
Alpert and other leaders.
But - II Timothy 3: 1-8 is also about a loss of sound doctrine in the Capital C Church, maybe as a part of the shift in culture in the Me Generation.
Verse 5: "Having a form of godliness, but denying the power thereof: from such turn away."
Verse 7. "Ever learning, and never able to come to the knowledge of the truth."
Verse 8. Now as Jannes and Jambres withstood Moses, so do these also resist the truth: men of corrupt minds, reprobate concerning the faith." These verses describe apostate Christians in the Church at a later time "in the last days (when) perilous times shall come."
These three verses describe what can be called the II Timothy Church in the last days.
Then Luke in Luke 17: 26-29 says as a prophetic revelation with a more specific time reference: "And as it was in the days of Noe, so shall it be also in the days of the Son of man.
27. They did eat, they drank, they married wives, they were given in marriage, until the day that Noe entered into the ark, and the flood came, and destroyed them all.
28. Likewise also as it was in the days of Lot; they did eat, they drank, they bought, they sold, they planted, they builded;
29. But the same day that Lot went out of Sodom it rained fire and brimstone from heaven, and destroyed them all."
Dean Gotcher makes this comment on the mind of those at the times of Noah and of Lot and of Luke's prophecy in Luke 17: "God cannot speak into the pre-flood, Tower of Babel, Sodom and Gomorrah, dialectic mind."
What is the dialectic mind? It is seen in the statements made by the serpent to Eve in Genesis 3: 1-6 and in the arguments made by the Pharisees to Christ in John 8: 32-45. In the Greek of I Timothy 6: 20-21 Paul very briefly warns against the use of the dialectic.
"O Timothy, keep that which is committed to thy trust, avoiding profane and vain babblings, and oppositions of science falsely so called:
21. Which some professing have erred concerning the faith. Grace be with thee. Amen."
The key Greek says και αντιθεσεις της ψευδωνυμου γνωσεως, or "and anti-thesis of falsely called knowledge."
αντιθεσεις, or anti-thesis, is a technical term in the early Greek philosophy of the διαλεκτική, or dialectic, before the time of Christ.

"Dialectic (also dialectics and the dialectical method), from Ancient Greek διαλεκτική, is a method of argument.....The word dialectic originated in ancient Greece, and was made popular by Plato in the Socratic dialogues."
