You don't find it surprising that the followers of Jesus murdered a married couple? I think most people, believers and non-believers alike, would think your analysis has gone off the deep end. Doesn't it make much, much more sense that the story was apocryphal and intended to serve as an object lesson about the importance of sharing the gifts of your life with the church?
Que? What on earth, or more specifically in the history of Christianity, would make this seem even slightly unusual?
