I have read a varying opinions concerning progression after the judgement between kingdoms. I know that Joseph Fielding Smith states in Answers To Gospel Questions that progression from kingdom to kingdom is not doctrine, however I have also heard that the brethren in times past were not in agreement with this stance in particular B.H. Roberts, does anyone have any current references on this subject or even past references would be great. I would also like to here the boards point of view.
