It's simple they pray on the matter.
"Dear god we have a problem! You gave us some bad information about the pedophiles in the organization also about the years 1975, 1918, 1925 and 1914. We have dozens of book with false information with 'old/new light.' Remember the time back in 1971 when you told us you couldn't divorce your mates if they were gay or having sex with farm animals."
"So what do we do now?"
God of course says. "Burn the Books!"
