It appears my point is being missed. I'm not stating the pre-trib rapture is or ever was the predominate view in all of Christianity. I only pointed out that among those who hold the pre-trib rapture view, the predominate view was the rapture would occur before Christians knew who the anti-christ was but now the view is shifting to where many say the anti-christ will be revealed prior to the rapture.
Thus my question regarding what is the reason for this shift and, within the pre-trib rapture view, what Scripture supports one or the other position?
If other end times views had or have some impact upon this particular matter then I would like to know. Otherwise, this particular thread is only dealing with a specific point of question and not what other end times views are out there and what one is or isn't more biblically sound.
