Christianity has much more historic veracity that Mohammed. Mohammed also was concerned that he was demon possessed but his wife convinced him otherwise. Mohammed also was a pedophile.
There is NO comparison between Islam and Christianity.
You don't even believe in the same God as Scripture Kosta, if you believe it took a single Jewish man to re-work the Christian message in order for it to survive.
My goodness you have astounded me tonight. I have come face to face with a real live apostate, that is if you ever were close to the truth at all. With your words, you show you reject a Sovereign God who is truthful in saying that His Words will NEVER pass away. You reject 3/4 of the New Testament and more. You reject the teaching of your own church. Kostaism is your religion; but by any other name it is merely humanism repackaged. Man is placed above God and the definition of what is God is left up to man.
Make no mistake, you preach a different gospel. In our country you are allowed to do that. In our country you may even call it Christianity. But God doesn't operate according to the rules of our nation. And one day each of us will give an account for what we did with the testimony that He left us.
The comparision between Muhammed and some forms of Christianity is in their view of scripture - not the same scripture but their view of it as 'Written directly by God.'
This is fundamental to Islam, most definitely not to Christianity.
