i'm not talking about translations but that is its own can of worms.
Theres protestant, Catholic, and orthodox versions each with different books in them. Ive always been partial to catholic and orthodox bibles cause im more deferential to their authority structure. But ive never really been able to pick between those two churches as to which is a superior structure. I suppose Catholic but im not sure
I use the 66 books - that of Anthanasius determined were the preserved books - and which were commonly used by the church congregations back then. This included the 39 books of the Hebrew OT - 22 books actually - some were combined and followed the Hebrew Alphabet. And the 27 letters of the NT.
The Roman Catholics hold to these books plus some others. The Orthodox and the High Anglican subscribe to the same. The Ethiopian congregation holds to some other books.
Probably i hold to these because I was raised protestant and the arguments for these made the most sense. If the Jews rejected the apocrypha as canon, then I suspect that too be a valid argument to reject it. Similarly, the NT books - tend to have different flavours. Anyone who has read the dead sea scrolls - and checked out the different voices - soon come to a similar story. It's interesting that those who reject Jesus as God, tend to consider some of the other letters which had been rejected by the church - as more authoritative. I suspect that this tells us something in the first place.
Personally, I think the Holy Spirit gives us the grace to believe some books are correct and some are not. This is why Luther didn't reject some books even though he would have - if he had a choice. He hated James, but couldn't reject it - since it has been confirmed by the Spirit of God. The same with Hebrews and the book of Revelation. The fact that I think the Holy Spirit agrees with just the 66 books - is of course my prejudice.
Translations of the ancient languages have different purposes - yes all for understanding - but some prefer more wooden literalism and others prefer more contemporary understanding. Some have different underlying manuscripts. The KJV has a different Greek text than the ESV.
Still, notwithstanding the differences in texts, the unity is staggering really. At least for those who have studied such things. Most Christians still tend to fall within the Apostles Creed. These are fascinating really.
