It has been noticed by me that over the last few decades there has been a shift in the teachings of Christian theology. This shift is in the areas of our antediluvian period (the time before the flood) and the eschatology period (the time of Revelation).  I have found that the teaching of the antediluvian period primarily starts at Genesis chapter 3:6, after the eating of the fruit. This is believed to be the period known as the Fall of Man. The time that sin entered the earth.
