Does not a partial preterist or historical theology imply or say that none of the prophecies written in the First Century apply to the Christian ekklesia in the latter days? Here are some of those prophecies that Christians have used to support the identification of an apostasy beginning in the 19th century and progressing now in the 21st century - II Thessalonians 2:3-12, Luke 13: 20-21, Matthew 24: 11,23, II Peter 2: 1-3, I John 2: 18-19, I John 4: 1-3, I Timothy 4: 1-3, II Timothy 3: 1-8,and II Timothy 4: 3-4.
The ekklesia itself when it is in a time of apostasy does not acknowledge it is in apostasy. Pointing out that the ekklesia is in apostasy is the work of the remnant. And so the partial preterist or historical theology is in disagreement with the remnant in 2017.
Bringing up Francis Schaeffer is interesting because I corresponded with him in 1984 at the time he wrote his last book, The Great Evangelical Disaster - of 1984. I had written a book on the Counterculture then which the Conservative Christian book publishers did not like. One editor said the Church was not interested in the Counterculture. Schafer said he understood what I was wrestling with. He was interested in the Counterculture. In some ways, Schaeffer's writings and his ideas led into the remnant which exists now. For example, his house church, L'Abri Fellowship, was one way of exit from the church in apostasy, and obedience in part to the call of Revelation 18: 4 and to the explanation in Revelation 18: 23 of what it is we are called out of.
I remember the time in 1979 when I was in the stacks of the main Library of the University of Texas and saw the Greek text of II Timothy 3: 1-8. I could not read any of the Greek, but that text seemed important to me then. Near that time I talked once with a Southern Baptist Preacher in Austin and remarked to him that II Timothy 3: 1-8 was about what was happening in 1979. He paid no attention to what I was saying. I suspect Scaeffer might have paid attention.
