While watching 'Discovering the Bible' on the Smithsonian Channel, I learned that the oldest bible in print is the Codex Sinaiticus. It contradicts today's accepted bibles, (the Holy Bible, and the King James Bible) y a great deal. The Codex's version doesn't include 12 verses of Mark's gospel that describes Christ arising from the dead and revealing himself to 500 eye witnesses. A most troubling problem for modern christians to say the least.
The problem for christians today is that nothing substantiates their version of the bible. Today's bibles are copies of bibles that were "created" in the 11th century. These bibles are full of mistakes and political edits. Plus there is no outside source that validates their claims.
Now the Codex lays to rest about the controversy of 500 eye witnesses that saw jesus rise again. It never happened. In the Codex, the Gospel of Mark, christ's tomb was visited by a handful of women that found the tomb empty and disturbed. They were overcome by fear and told noone what they had discovered. There were no firsthand accounts, no eye witnesses, and no accounts outside the bible of the event. Even at that the accounts in the bibles today are much different than the accounts of the oldest known bible.
The Codex was discovered by Constantin von Tischendorf in 1844 at Saint Catherine's just below Mount Sinai. The Codex was written in Greek which also leads to speculation about how accurate they are, even though they are only 300 years removed from the time of christ.
