This is a response to Alan on a discussion started by Rob at www.straightshot.blogspot.com
Alan you wrote "It's really a question of how do I get started and how can I place my trust in the Biblical documents...." Let me outline one way of starting. I think the place to get started is not with the Bible at all but rather with the historical event of Jesus. Was Jesus literally/historically raised from the dead? With that as starting point the whole conversation about the Bible changes. You're not asking 'is the Bible true?' but rather is one of its claims true. Then you would investigate the various books of the New Testament first, since they deal primarily with Jesus. Initially, I would keep these books separate from one another. They weren't written together and if your dealing with them apart from faith then it makes more sense to take them one at a time. The church decided they belong together, and I trust that decision. But since you're not asking the question 'is the Bible true?' you are now free to ask 'is Luke true," "is John true" etc. Do the Gospels according to John, Luke, Mark and Matthew provide evidence that Jesus rose from the dead and are they trustworthy?
Jesus came before the New Testament. The message about Jesus came after Him, but before the New Testament. The church was established by those messengers of Jesus before the New Testament was written. That's partly why I think it's important to answer the question about Jesus, before you dive into the question about the Bible. If God raised Jesus from the dead, then Jesus' claims about Himself have been vindicated by God. Jesus claimed that He was the fulfillment of the law and He often quoted the Old Testament in refrence to Himself and what He was up to in the world. That's why we read the Old Testament at all. And whenever we read it, we ought to be looking for Jesus.
Now this is a long way around at getting at your question regarding Adam and Eve and original sin and the need for salvation at all. But I think the starting point is so significant to where we end up in the discussion. Let me know if this different way of approachiing the question changes anything for you.
You also write "Pretend I am a Hittite, you don't have any other Biblical writings available, and you are coming to me to explain to me what sin is and why I'm condemned to an eternity in Hell..." I suppose in that situation I would explain sin as being separated from God. None of us know God like we know each other, talking and hearing and walking with each other. Sin is the situation of separation, we're born into it. The story of Adam and Eve is an explanation of how all this started, but it's a universal explanation not a particular one. Humans want and have wanted since the beginning to decide for themselves what's right and wrong. This is a fundamental rejection of God's rule in our lives. God gave us over to this decision and we are born to parents caught up in the results of the decision every human makes. Even the Hittite :). But God loved us so much, and wanted to bring us back to Himself that He became human in Jesus and lived a human life that submitted completely to God deciding what's right and wrong. "If possible take this cup from me, but not my will but yours be done" prayed Jesus. Jesus then becomes our way back to God, when we're united to Jesus in Baptism(Rom 6). As far as being condemned to an eternity in Hell, I would never frame the question of salvation that way. I don't think salvation is primarily about not going to Hell. I think it is primarily about a return to a relationship with God made possible by God through Jesus. I don't know much about Hell and it is not fear of Hell that motivates me to encourage people towards Christianity.
You also say something I used to say pretty frequently "If one part (of the Bible) is in quesiton, it throws everything in question and we don't have much to talk about;..." I don't think that's true. I don't think that Biblical innerrancy is necessary for the truth of Christianity. Actually, I think that it gets in the way of Christianity by making the Bible the central focus of faith rather than the ressurrected Christ. The Bible is a witness to Jesus and everything in it should be judged accordingly. The problem comes when in order for Jesus to be true the Bible has to be. That's backwards. Jesus is true in and of Himself. The Bible is true in so far as it gives witness to Jesus. The Bible gets its truth from Jesus, not the other way around.
Anway, I'll stop now. My goal is to urge you to reframe the questions and have you start from Jesus rather than from scripture. What do you think?
