What do you believe Shakespeare's (or De Vere's, take your pick!) religious beliefs were? Agnostic, atheist, humanist....or was he just a really gifted alien life form?
There were plenty of people living in the sixteenth century who didn't subscribe to the current religious beliefs, as there have been since recorded history began, but since we don't even know who really wrote 'the works of Shakspeare', we have no idea what their beliefs were. The works seem intelligent enough to have been at least agnostic, though.
Edward de Vere, Lord Great Chamberlain of England, was a loyal subject of her majesty the Queen, so he was at least nominally an Anglican. Apart from that, his famous soliloquy "To be or no to be" reveals that he was definitely not an Atheist, perhaps an agnostic.
