Thank you!! Constantine is totally irrelevant to the OP, so I edited him out. Can you please respond to the main topic ?
Sure. The contents of the Bible are not affirmed by any single person, or group of people; but rather is the affirmation of the historic Christian Church,
a consensus of the Faithful.
There are differences in the Canon between groups of Christians, but these differences lay almost exclusively on what are usually known as the Deuterocanonical books (or just Deuterocanonicals), they are sometimes called "The Apocrypha" among Protestants (going back to Luther's German Bible translation); but they should not be confused with the more broad term of "apocrypha". The Deuterocanonical books consist in those books found in the Septuagint, but which did not ultimately make it into the Jewish Tanakh. It also refers to the "additions" to the books of Daniel and Esther that are found in the Septuagint rather than the Tanakh. For example the Greek version of Esther found in the Septuagint makes mention of God and prayer, but Aramaic Esther (the version found in the Tanakh and Protestant Old Testaments) does not.
The only exception to this is the rather unique case of the Ethiopian and Eritrean Churches, who are the only historic Churches to accept books such as Enoch and Jubilees.
Outside of this more focused and nuanced debate concerning the Deuterocanonical books, there just isn't any discrepancies, the same books are found in all of our Bibles, because these are the books which definitely have been received and accepted across the Churches around the world. A consensus of the Faithful.
The Church has always maintained that certain books, as opposed to other books, are vital and should be read for the edification of the Faithful, that's what the Scriptures are. The collected writings which the Church affirms to be read in the context of worship; and the reason why these writings are suitable for this (and not others), is because the Church has historically agreed that these books (as opposed to other books) have the hand of God on them, they are divinely inspired. They are, as St. Paul says, "God-breathed", divinely inspired, the people who wrote these books were "carried" by the Holy Spirit. Their words are not their words only, they are by the Spirit the very word of God for us.
If someone came along and attempted to make a "Bible 2.0" it would have no meaning for the Christian Church. People are free to write, or gather whatever texts they like, but it can't be the Christian Bible because we already have one. The Bible 1.0 is just as good today as it's ever been. Because the divine word in Scripture is the unchanging, enduring, faithful word of God. And the Church confesses, "The word of the Lord endures forever".
Whitewashing the Bible won't improve it. The ugliness we sometimes see in the Bible should be taken seriously, not as something to flee away from, but instead to be engaged with. The Bible is blatant in its honesty concerning the weakness of human beings. It shows us at our worst, it shows us that even the saints and heroes that we revere ware broken, fallible, miserable little sinners just like the rest of us. There are stories in the Bible that are hard to read. And yet through all of that, there is this tiny little stream flowing down from the mountain, and as we continue to look through its pages, we see that river growing wider, stronger, other streams start trickling down into it. Where this river is heading we can't see yet in the Old Testament, but it's heading somewhere huge. The New Testament shows us where that river was heading all along, it's Jesus.
And that's really the most important part: The Bible is about Jesus. Jesus is proclaimed from the pages of Scripture, both the Old Testament and the New. From Genesis to the Revelation, it is all about Jesus.
Sure, the stream might begin trickling on some sharp rocks, there may be some jagged areas, but the trickle is flowing through them, into the massive stream that is Christ. Just because you see the sharp and scary rocks of the book of Joshua or in the books of the Kings doesn't mean that Christ is not there--He is. The trickle becomes a stream, and the stream a river, and that river opens up into the fathomless ocean of God's mercy and love.
