Watermelon,
I am confused too so don't feel like you are alone.
I have never been able to figure out why people want to argue about what Jesus died on.
It seems like such a trivial point to me. The main point should be as far as I am concerned is than an inocent man (supposedly God's Son ) was put to death as the story goes.
Who cares what he died on, stake or cross, the results would be the same either way!
