For a Christian, responding to a satanic rant is optional. We have the option of shaking the dust off our 'sandals' and simply walking away from any house where the Gospel is not welcome.
You patently have no understanding of the Gospel, so there is nothing with which to engage. Go back to Jn. 3 and start again at the beginning, and when you have acquired at least the most basic understanding of what is involved in true conversion, then we might have a basis for taking the 'debate' forward.
