Let me repeat myself....
the issue is not are there seperate dispensations as the WHOLE church has understood the word, but is the theology, eschatology, and method of Bible slicing of Dispensationalism Biblical. You must answer the charge, not simply ignore it and focus on something which you think you can get agreement.
It sounds to me like you are agreeing that separate epochs/eras/etc. do exist.
Good. I agree with that.
Now, do you agree that God was in charge during the “era” of Eden?
