I think you're pretty much culture bound in your request. Being from a church that has a confession that might mention such a thing, you forget that many churches are not nearly so formal. Some don't write lengthy confessions at all.
Then I'm surprised you would make such a assertion as being "historically true". How far back does your view of history go?
If you can't point to a document or something that can be scrutinized, what are you basing your assertion on?
False prophets attempting to predict the outcome of both world wars hurt dispensationalism's credibility. they were always confident that Bible prophecy was being fulfilled right before their eyes, but the subsequent events always forced them to continually re-evaluate what was being fulfilled. Bible scholars had either grown silent or abandoned the viewpoint after the mid 1960s. Then there was a revival of interest when Hal Lindsey published the best selling book of the 1970s: The Late Great Planet Earth. In it Lindsey declared that "no self-respecting scholar who looks at world conditions and the accelerating decline of Christian influence today is a post-millennialist." Lindsey wold have saved himself much embarrassment if he had interpreted world conditions in light of Scripture, instead of trying to read into Scripture his understanding of current events. Lindsey helped bury dispensationalism with his unfulfilled predictions and there were plenty of post-millennialists around to attend the funeral!...
Although the Church was supposed to be in ruins, it experienced the greatest revival since Pentecost during the end of the 20th century. Peter Wagner declared, "We are in the springtime of missions." In 1900 the ratio of non-Christians to Christians worldwide was 27:1. In 1989 that same ratio was 7:1. Although there were repeated attempts to connect the year 2000 with something cataclysmic, "wolf" had been cried too many times. Nothing could revive the old theory and it passed away leaving a host of red-faced prophecy expects and a huge surplus of obsolete books and charts.
