I posted these quotes from Calvin on the other thread, but they're applicable here, too, in light of the "veneration" cast upon the creature rather than the Creator...
"All who forsake the word fall into idolatry." (John I)
"Every one of us, even from our mother's womb, is a master craftsman of idols." (Acts II)
"Superstition is always fearful." (Acts II)
"Though all men do not worship the same idols, they are all nevertheless in bondage to idolatry." (Romans)
"The knowledge of the true God alone is sufficient for the abolishing of all idols...All is idolatry which men invent without his word." (Acts II)"Man's mind is like a store of idolatry and superstition; so much so that if a man believes his own mind it is certain that he will forsake God and forge some idol in his own brain."
And my personal favorite...
"Superstition is always cruel." (John I)
