That scripture "popped" into my mind just last night. And He, who was without sin, cast no stone either, but forgave her, "Neither do I condemn you; go your way. From now on sin no more."
My personal opinion is that many of those who are adamant about certain doctrines, spend too much time listening or reading only one or two theologists. We must remember they are human only, and the bible should always be our final Word. I almost fell into this trap myself.
