Good synopsis by Suede;
Preterism believes that various prophecies were actually supernaturally fulfilled in the events of the incarnation and the first century. Futurism is associated with the disbelief of the Jews and jewish fables and also the talmud.
Futurism/dispensationalism was a doctrine and system that I feel was formulated by the pharisaic, atheistic or rebellious type of socialists to break down the progress of America as it departed from the rule of the crown into a more individualistic and Spirit awakened society even attempting to instill and allow for true Christian beliefs and to allow for the self governing Law of Love into society. Laws of individualism (of the new covenant) and laws of cause/effect and responsibility. Laws that support that if one desired to proclaim Jesus, the Holy Spirit; as his/her only king, (as some did) they would be free to do so.
Cornwallis had told George Washington at his surrender that a holy war would now begin in America and that eventually it's churches which were once bastians of freedom would be permeated with and used to teach Judaism....
Formulated in Europe in the early 1800's or well before, futurism/dispensationalism grew by leaps and bounds through scofield and his bible commentary and his behind the scene aids; through the Niagara Bible Conferences (NBC) which became a futurist/pro Israel springboard; and then by extension of the NBC, the bible college movement. A VERY High percentage of bible colleges still hold to the futurist perspective and even state that books such as Daniel or others will be taught from the futurist perspective. (Philadelphia College of Bible) Other avenues of indoctrination have been in the early 1900's in a series of pamphlets titled "The fundamentals" and Biola bible school/university. Some speculate that the Standard Publishing company under Rockefellers watchful eye also injected some untruth.
Full preterism greatly reduces the importance of the professional paid clergy and the 'religion" called christianity. In full preterism the Living and abiding Holy Spirit of Christ is relied upon as the teacher in patience and faith while resting in His unconditional acceptance and Love.
There is no pressure of guilt to be approved by having the 'right answer' or 'right theology' or be indoctrinated into those answers especially as it pertains to the teaching of the so called 'church age' and the blessing of national Israel. There is no twisting of the scriptures.
Fulfilled perspective recognizes that Christ came in power and glory Revealing himself as Creator through the armies of Rome as prophecied in Deut 32, iis here now in the indwelling Holy Spirit, never left and does not need to come again for a final ending. The end of all things and the full establishment of eternal laws was at hand at that time.
Futurism says that the world will get progressively worse and the believers are raptured while the world is re-made. Preterism says that those of the kingdom of God established in Power are instilled with Royalty to maintain goodness (light)in the world and to work towards making it better according to their understandings of Life and the laws of eternal Life.
Fulfilled Preterist perspective is the only sound and rational perspective that views the Creation as Good and it's Creator victorious and accepts the supernatural aspects of a living God able to foreplan, foretell and fullfill events which establish eternal laws of Life. Putting the historical occurances of the first century back into the formula of the prophecies proves their fulfillments much like an algebraic or chemical equation can be 'prooved'.
These concepts do not jive well with those who wish to perpetuate, expand and support the marketed aspect of the "RELIGION" of judaized christianity. This I think is one of the reasons that full preterism cannot be discussed in general theology.
Furthermore, and perhaps most significant, full preterism stands against he scofield bibles missapplication that those who bless physical genetic Israel or conditional covenant national corporal Israel will be blessed, thus it stands against the dominant indoctrinations of the last 160 yrs calling them false and 'lies'.
Enough for awhile.!!!
