We believe the bible to be the inerrant word of God. If that’s what you mean by perfect, then yes.
We also strongly object to the LDS claim that scripture was lost or changed by the early church. We reject any scriptural revision by Joseph Smith or anyone else claiming revelation to re-translate scripture.
We further strongly object to Martin Luther’s removal of certain canonized books of the bible, and also his attempt to remove others. He had no authority, nor claimed revelation to do so.
We do support translations of the bible into the language which we currently speak. In other words, scripture doesn’t have to remain in 19th century English.
