Check out this article:
It gives a history of how some Mormon doctrine has changed over the years.
Any of this sound familiar?
In fact, Mormons have been revising their doctrines all along. The revisions are driven by cultural and political changes, though the church attributes them to revelation.
Mormon leaders didn’t see the light till they felt the heat. Beginning in 1882, the U.S. government outlawed polygamy, jailed church officials, and confiscated church property. In 1890, the Supreme Court upheld the confiscations. That’s when revelation struck the church’s president, Wilford Woodruff:
President Woodruff saw that the Church’s temples and its ordinances were now at risk. Burdened by this threat, he prayed intensely over the matter. “The Lord showed me by vision and revelation,” he later said, “exactly what would take place if we did not stop this practice,” referring to plural marriage. “All the temples [would] go out of our hands.” God “has told me exactly what to do, and what the result would be if we did not do it.”
Woodruff issued a manifesto pledging that the church would no longer sanction polygamy.
The article goes on to speculate that similar cultural or legal pressures could force the Mrmons to receive a new "divine revelation" about homosexuals. JWs seem to respond with "new light" to cultural, economic, or political pressure as well.
How much you wanna bet that, for example, if the US threatened to remove the tax-exempt status of any 501(c)(3) that refused to admit homosexual members, or threatened to confiscate property of religions that refused to perform gay marriages, suddenly there would be "new light" emanating from the JW popes?
