It's not always just what devotees say that is wrong it can often be what they don't say. For example, not a single one of the "42 authors" ever met Jesus while he was alive. The four canonical Gospel writers were all anonymous until the names Matthew, Mark, Luke and John were added as authors late in the 2nd century. There is no contemporary eyewitness testimony for Jesus at all whatsoever. Nobody ever wrote about Jesus during his lifetime and the canonical gospels didn't exist as we have them today until around 180CE - that is what the literary and historical records show i.e. evidence that actually exists.
