We, as infallible as we may think we are (or the Bible translators), are bound to mess a few things up. No translation is 100% exactly right.
I tend to give God more credit than that. I figure if He is able to create everything then He should be able to keep His word perfect. No matter how infallible we are.
Either He doesn't want us to have His perfect word or He does. If He does, where is it? If He doesn't, why not?
The number of Christians tortured and put to death over the doctrine of baptism by the Catholic and Protestant churches clearly shows that doctrine is important and makes a lot of difference.
