In the 2007 Resurrection article they are declaring that divine truth is revealed to them but they are not sure how and think it may be through resurrected persons. At one time they claimed their knowledge was through careful study of the bible but this article makes the claim that some revelations are not limited to interpreting the bible.
If they are not sure how new information is revealed to them, or by whom, then they cannot be certain that they are being fed wrong information and accept it no matter from what source it comes from.
