If you believe the opening post then you'd believe anything.......
" I do not believe in a personal God and I have never denied this but have expressed it clearly. If something is in me which can be called religious then it is the unbounded admiration for the structure of the world so far as our science can reveal it."
Einstein Professor : You are a Christian, aren’t you, son ?
Student : Yes, sir.
Yes HappyCats,
That sums up Einstein's beliefs.
Unfortunately Einstein is the happy hunting ground of those using misinformation to further their cause.
Just the first two lines of the story posted should lead one to reach for the BS button. If Einstein had any affiliation to a monotheist religion it was not towards Christianity, but Judaism.
