Interesting op ed piece by Bloomberg View columnist on this subject, Signs of hope for gay LDS faithful, who writes "..the prospects for future tolerance. ...are stronger in a faith that believes in continuing revelation than they are in one ....that cleaves to traditional teachings..." He goes on "the phenomenon of continuing revelation means that no element of LDS doctrine is totally unchangeable" citing their changes to plural marriage and the racial issue. He attributes the possibility of change more to LDS obedience to U.S.law and constitution than to compassion, etc. but still an interesting thought that the church may still change in the future their current stance, more so in obedience to law.
Partially mirrors JWism in the changing doctrine, but tolerance for gays? Not so much. Not holding my breath on that one.
