On speculative theology

In the New Testament there were two groups of Jews,
The Pharisees who believe in resurrection and the Sadducees who don't but both are considered orthodox and well Christians could have been either side until it was revealed by Christ there is an afterlife. And this is a lesson that Christians can learn. Except for the major tenets such as the nature and divinity of Christ most finer points of theology can be argued both ways. What is the really the problem is we have yet to receive perfect and total revelation maybe because we are not ready. And someday many hundred of years later it will be revealed until then i would be pretty petty to kill each other over whether the rapture come before, during or after the tribulation. Speculations on theology is fun but not a matter of life and death or even salvation.
