Christians debate on whether or not God told both Adam and Eve to not eat from the Tree Of The Knowledge Of Good And Evil in The Garden. Here is a view on it by Rev. Dr. Christopher R. Smith, who is an an ordained minister, writer and a biblical scholar. This post from his Good Question blog seems thorough and accurate. It's a good answer that leads me to ponder my next question of why Adam did not stop Eve, since he was with her when she ate.
Did God give the command not to eat from the tree only to Adam?
