Earlier I stated that we fundamentalists shouldn't argue with or flame those who contend that maybe Adam was a parable.... if they still understand through the "parable" that the message from God is this-- God created us, mankind has fallen by choice, mankind needs a savior, man suffers dies and is in pain because of his fallen state, and that Jesus is this savior. Boy was I flamed (although not the first time). Those who believe in error should be corrected. Your belief is in error. If you base your belief on a false understanding of scripture, could it not follow that your belief would also be false?
Your guide should be:
All scripture [is] given by inspiration of God, and [is] profitable for doctrine, for reproof, for correction, for instruction in righteousness: That the man of God may be perfect, throughly furnished unto all good works. 1Ti 3:16-17
Unfortunately your quote from Timothy doesn't definitevly say if Adam and Eve is a parable or not. I believe they were literal people. But I'm certainly not going to flame someone who believes they are figurative if this person ends up with the same message from God that I get. If this person gets the same instruction for righteousness, reproof and correction. But hey... I'm not a Pharisee or an exmarine either one. So there you go.
