"The differences among the manuscripts have become great, either through the negligence of copyists or through the perverse audacity of others; they either neglect to check over what they transcribed, or, in the process of checking, they make additions or deletions as they please." Origen, Commentary on Matthew, 15.14.
So when confronted by a nonbeliever's accusation, Origen denies that Christians ever changed any texts, but when writing to his fellow Christians, he complains about the exact same thing himself! This was a VERY common charge amongst Christians in the first 300 years. And considering that Origen was condemned as a heretic himself, who knows what he considered true or false in regards to his mystery religion?
