I don’t think that throwing out or destroying a worn or an unwanted Bible is at all the right thing to do. So long as a Bible is one that is one that is allowed really to be the Bible, through the work of the translators and the justifiable editorial aspects of it, to destroy a Bible is sacrilege at worst, lack of heed to proper values in other cases. However a Bible looks too worn for you to use, someone might be quite pleased to have it free. I have left surplus Bibles on the benches where subway riders may fine them, hopefully to make some use of them, if only to pique their curiosity or to leaf through it to see if they would like to buy a better copy.
As for the Jehovah’s Witnesses perversion of Scripture, the New World Translation, that is the kind of thing, deceitful and genuinely perverted, that one might let self-destruct or for which you might want to hasten its disappearance from existence! Even then, it might be good for a Catholic who does apologetic study and work to retain it as a specimen.
And by no means soever should one abuse or destroy a copy, even one without that version’s “Apocryphra” (deuterocanonical writings) of the Authorised “King James” Version (A.V.) of the Holy Bible! No way, José! That version has done more to convert the world than any other Bible published and merits some respect, even if you prefer, with good cause, the best Catholic rival to the A.V. Bible, the Douay-Rheims-Challoner Version. You can convert a Protestant or sectary to the Catholic faith when using the A.V. Bible, so why should you abuse it? Atop that, remember that the American bishops have sanctioned the use of the A.V. Bible, so why should it be an object of Catholic wrath?
Have care for those old and/or unwanted Bibles. You may not be able to use it, but somebody else, maybe even the Holy Ghost, very well could be able to use it profitably in evangelism or otherwise draw other spiritually worthy use of it.
