Truth cannot contradict itself, so agreement with the other books of Scripture was only logical, as was historical accuracy - if the facts of a book were not accurate, it couldn’t have been from God.
But what is truth? - (hmmm... heard that before...) Is it your interpretation of a verse or is it mine? It is your sect's interpretation or my sect's interpretation? Not as clean and checklist checkoff simple as some would make it out to be.
We are in the year 2022. There is still debate as to the origins of which early church manuscripts, were the most accurate. Example:

Comparing the Greek and Aramaic New Testaments
Matthew 19:24 (a camel or rope?)
Greek Translation (KJV): "And again I say unto you, It is easier for a camel to go through the eye of a needle, than for a rich man to enter into the kingdom of God."
Aramaic text: "And again I say to you, that it is easier for a rope to enter into the eye of a needle than for a rich man to enter into the kingdom of God."
