You make it sound like we have no idea what the originals might have said, and there fore we have no clue what was intended in any part whatsoever and that it is completely unreliable ...

But it is true we dont have originals.. but we have tons of evidence and it is very likely we are very close to what was originally written.

One advantage of dead languages is that the meaning does not change. We cant have a speaker of that language inform us, but that person would be using a different version of that language.

Even Shakespearean Englsh is a bit different than modern english, and American English is even more different. So would a modern day english speaker understand Shakespeare as original written better than someone who lived at that time? I doubt it.

There are like 6000 copies of ancient texts from before 1000 a.d.,.. and fragments before 100 a.d., and they are like 99 percent the same. That is pretty heavy duty evidence.

There are no copies with wildly different stories.. There are not 15 versions of the stories Jesus told that are radically different. The differences are in the shade fo meaning of one word here and there, that have no bearing on the meaning of the story itself.

You can trace the translation of every single word back to very old texts, and even study how words have been translated since about 200 a.d.

Most bibles have footnotes that explain textual differences and those differences do not add more than one or two pages to the more than 1000 pages in the whole.

Also people claim books were written at a certain time. These were hand written on big scrolls. It would have taken some time to write even 1000 words. None of them could have been completed in a year.

Say the gospel of Matthew, written before 70 a.d., but it may have been in the works for 40 years.

There may have been parts written even while jesus was alive... that is just as likely as not.

I have studied ancient greek for about 30 years and have translated about half the NT myself from the oldest available greek texts..

I believe we have a very reliable account of what was intended.

Most of the time when people say "as originally written" they mean the oldest texts we have.

I am pretty confident we have the "original" stories , with remarkably few textual issues.
