In another thread, the topic of whether the non-Catholic bibles should be burned or not was raised. As objection to that notion, one person wrote:
Whereas any translation of the Bible, even if it be mediocre and not contain all the requisite books, is still the word of God. Even if the truth of it be somewhat obfuscated by translation or removal of books. Just as a diamond is still a diamond and still valuable, though it be in the hands of a thief or lose a little of its lustre through unskilled cutting of the stone.
Pure evil is never presented to the tempted soul as such. The greater the good in which the evil is presented, the more powerful the evil is. For example: rat poison is 98% nutritious, but no sane person will eat it simply because it contains some good or is mostly good. If the book in question is not the complete Holy Bible, certified by the Church as being an accurate and faithful translation, neither adding nor subtracting from the Latin Vulgate of Saint Jerome, then it’s at best an ersatz translation and at worst an instrument meant for the destruction of souls.
If a person happened to come to the one True Faith by reading a heretical book then it’s not the book that converted them but God’s grace which allowed them to convert in spite of the un-Catholic book. If they didn’t know better before it’s not a problem because God won’t hold that against them. But if they know better now, then they need to distance themselves from it otherwise they’re maintaining an attachment to something which is objectively an occasion of sin against the Faith.
