The fact that Jerome quotes part of the Freer logion (the additional text not seen in other codices) is pretty good evidence of its very early presence in some manuscripts.

Christians who have bought into the received notion that the New Testament has been preserved word for word or line for line in an unbroken succession would be well served to have a close look at not just the codex Freer discovered, but it all the earliest extent codices.

None of them are identical, and some of the differences are very significant. A close examination reveals clearly that exact preservation of the earliest texts did not happen.

This is not a startling concept to scholars, who take the above for granted, but it is not what the average Protestant Christian learns in church.
