This may be somewhat off topic, but on divorce, it's worth noting not only that Christians have been "re-interpreting" that teaching since it was given, but that the quoted passage from Matthew is itself an example of this process. If you look at the corresponding passage in Mark 10, which was written before Matthew, you'll notice that Jesus forbids divorce under any circumstances. The Matthew version adds the clause permitting it in cases of adultery. Earlier texts are not necessarily more historically accurate than later ones, but in this case, it's hard to resist the conclusion that Mark's version more accurately represents Jesus' actual teaching, and Matthew's represents a watering down of this teaching in the later Christian community. So if Mormons have done this too, they're in good company.
