I have one question about this cube.
If, as you say, your God is a cube, why is it that he only appeareth as a square? Are we really too unworthy to see all three of his dimensions? How do we know that his priests are not lying and claiming he is a cube when in fact he is merely existent on a flat plane?
(I would pick apart the rest of this mess, but cba to find the Biology textbooks.)
