Pergunta: Será que a Igreja repudia a idéia de neutralidade na "guerra no céu?"
Question: Did the Church repudiate the idea of neutrality in the "war in heaven?"
President Kimball was reported as repudiating this idea following the 1978 revelation
Some members and leaders explained the ban as congruent with the justice of God by suggesting that those who were denied the priesthood had done something in the pre-mortal life to deny themselves the priesthood. President Kimball was reported as repudiating this idea following the 1978 revelation:
President Kimball "flatly [stated] that Mormonism no longer holds to...a theory" that Blacks had been denied the priesthood "because they somehow failed God during their pre-existence." 
The modern Church rejects this theory
Today, the Church disavows the theories advanced in the past that black skin is a sign of divine disfavor or curse, or that it reflects actions in a premortal life; that mixed-race marriages are a sin; or that blacks or people of any other race or ethnicity are inferior in any way to anyone else. Church leaders today unequivocally condemn all racism, past and present, in any form. 
Modern Church leaders teach that everyone who came to earth in this day was "valiant" in the premortal existence
Elder M. Russell Ballard, talking of today's youth, said in 2005:
Remind them that they are here at this particular time in the history of the world, with the fulness of the gospel at their fingertips, because they made valiant choices in the premortal existence.

Ostling told President Kimball's biographer and son that this was a paraphrase, but an accurate reporting of what he had been told (see footnote 13, citing interview on 10 May 2001).
