Despoiler of the World We Know

I am the spear in the side of christ
I am all you fear and spite
The flame that ignites your feeble church
The crushing defeat that you makes you hurt
I am the black smoke in the air
I am death and despair
The immortal spirit of the past
The one who makes you the last
Heresy! Bringer of the old cold
Heresy! Despoiler of the world we know
