I never was a fan of the cross, because of the argument that if your friend was shot but a gun, you really would want that instrument as a jewelry piece to wear around your neck.
The Reasoning book was really weak in providing a argument about the cross because the source they used was from a bious individual.
However, in recent times, a professor, Gunner Samuelson has researched the subject, and he favours the stake as Jesus' form of execution. I have also read over that thread of Leola, and appreciate her deep research, and explanation.
The bottom line is, who knows for sure? We weren't there. Who really should care? Should we really wear it on our necks?
