When studying and comparing different books of the Bible (like the many accounts of the 4 Gospels that you list in your common list of "errors" J5) it is important to look at who worte each of the books.
For instance: Mark wrote Mark. Luke wrote Luke. John wrote John. Different people. Different viewpoints. Yes, God inspired them, but each added their uniquie view of what they were writing. Thus, these are more likely differing points of view as opposed to actual errors.
Example:
Matthew was a tax collector. Very detailed in his record keeping. He would list the "official" father of Joseph- Jacob.
Luke, however, was a doctor, and the books he wrote go farther to recognize the women and their actions of the day. He recognized Mary's father, Heli, as the lineage of Jesus. (This would be Josephs "Father-in-law,")
Not an error, just two differnt people giving their unique views of the same event.
Say you and I get called into the police station to give testimony about an robbery that we witnessed last Tuesday. If we both give the exact same word for word speech to two different officers, they are going to we practiced it, compared it, rigged it, etc, and are hiding something.
But, if me being a mechanic makes me notice more about the getaway car, and you being (an example as I have no idea what you do) a clothing designer makes you notice more about the suspects descriptions and we both intertwine our unique viuewpoints into what we tell the cops- then it is apparent that what we saw really happened.
