Do you maintain that mistakes and interpolations by copyists were not possible in transcriptions of the Bible?

The Catholic Answers

Mistakes and interpolations were certainly possible, but by comparison of independent copies these are discoverable. Yet remember that the Catholic Church does not say that copyists were inspired. Inspiration is claimed for the original Evangelists. In so far as later copies or versions exactly correspond with their original writings they give the inspired Word of God. In so far as they are not exact, they do not.
