The Bible is riddled with repetitions and contradictions, things that the Bible bangers would be quick to point out in anything that they want to criticize. For instance, Genesis 1 and 2 disagree about the order in which things are created, and how satisfied God is about the results of his labors. The flood story is really two interwoven stories that contradict each other on how many of each kind of animal are to be brought into the Ark--is it one pair each or seven pairs each of the "clean" ones? The Gospel of John disagrees with the other three Gospels on the activities of Jesus Christ (how long had he stayed in Jerusalem--a couple of days or a whole year?) and all four Gospels contradict each other on the details of Jesus Christ's last moments and resurrection. The Gospels of Matthew and Luke contradict each other on the genealogy of Jesus Christ' father; though both agree that Joseph was not his real father. Repetitions and contradictions are understandable for a hodgepodge collection of documents, but not for some carefully constructed treatise, reflecting a well-thought-out plan.
Of the various methods I've seen to "explain" these:
1. "That is to be taken metaphorically" In other words, what is written is not what is meant. I find this entertaining, especially for those who decide what ISN'T to be taken as other than the absolute WORD OF GOD--which just happens to agree with the particular thing they happen to want...
2. "There was more there than...." This is used when one verse says "there was a" and another says "there was b," so they decide there was "a" AND "b"--which is said nowhere. This makes them happy, since it doesn't say there WASN'T "a+b." But it doesn't say there was "a+b+litle green martians." This is often the same crowd that insists theirs is the ONLY possible interpretation (i.e. only "a"
wink and the only way. I find it entertaining they they don't mind adding to verses.
3. "It has to be understood in context" I find this amusing because it comes from the same crowd that likes to push likewise extracted verses that support their particular view. Often it is just one of the verses in the contradictory set is suppose to be taken as THE TRUTH when if you add more to it it suddenly becomes "out of context." How many of you have goten JUST John 3:16 (taken out of all context) thrown up at you?
4. "there was just a copying/writing error" This is sometimes called a "transcription error," as in where one number was meant and an incorrect one was copied down. Or that what was "quoted" wasn't really what was said, but just what the author thought was said when he thought it was said. And that's right--I'm not disagreeing with events, I'm disagreeing with what is WRITTEN. Which is apparently agreed that it is incorrect. This is an amusing misdirection to the problem that the bible itself is wrong.
5. "That is a miracle." Naturally. That is why it is stated as fact.
6. "God works in mysterious ways" A useful dodge when the speaker doesn't understand the conflict between what the bible SAYS and what they WISH it said.
