Nope. Islam has never been peaceful. And in no way "just like Christianity."
No, we are not ALL God. Jesus spoke about His relationship to the Father as unique. Not an all encompassing pantheism. That would be meaningless and powerless.
Jesus clearly distinguished between God and not God in the scriptures.
We have a direct connection to God, through Jesus Christ. I am not Catholic.
Having a connection to God does not mean I AM God. That is a heretical jump that is dangerous. Put your trust in Jesus, not yourself.
On Judgment day Jesus is going to say to many "away from me, I never knew you…" Which is Matthew 7.
