Ellamae suggested that "[B]iblically and theologically death couldn't have existed before sin. It seems incompatible with Christ as our salvation, His death and resurrection. How do you answer that and remain a Christian?"

The "no death before sin" objection is certainly a serious issue to many conservative Christians.  Much ink has been used in writing about this topic.  

The issue was created or, at least, highlighted by Paul of Tarsus.  We have him to thank for making it a major issue in the history of Christian theology.  Others then took it up and ran with it and it has been a part of traditional Christian theology ever since.  

How do you continue to take Paul's views seriously and yet dispute the literalistic spin that he put on the Creation story to make his soteriological point?  

How about -- Paul is not infallible?  We all make mistakes. He made a mistake here.  If you don't like this idea, suggest some other way of dealing with the "Death before Sin" idea?.
