(Quoted from The Church of Tetris homepage.)
"The Church of Tetris is founded on the belief that all people should receive the glory of Tetris. Those who know of the Glory shall have peaceful lives filled with wonderful things. Those without Tetris shall continue on as all humans do. And those who oppose Tetris shall be crushed in a rain of blocks from on high."
The CoT has even sanctioned a prayer to be uttered whenever worshipping the one true Tetris.
Oh, Tetris, thy Glory great,
Give us today our daily blocks,
So that we may clear them.
And give us strength,
Through our gaps and mistakes,
To obtain a tetris.
