By chance are you against the Statue of Liberty as well? There are different ways of construing various passages originally written in Hebrew, and yours seems to be tending towards the iconoclastic/Islamic version (the extreme Islamic version came first, and then dribbled into Judaism and Christianity).
The universe is given to us to remind us of various things, some good, some not so good, because we need to be reminded of them.
Otherwise, God would have created Berkley and have been done with it. (The wacko 18th century Anglican Bishop-Philosopher, not to be confused with the California city named in his honour, or the school located there.)
No pagan graven image is to be set up in the context of worship including a place of worship, much less a demonic image, as such gives honor and invites worship. Such are found in pagan temples but are nowhere to be found in churches calling themselves Christian. It is hard enough to even justify any graven image made under the prerogative of man (versus commanded by God), let alone grotesque demonic creatures. And even when expressly commanded by God then you see the proclivity of man:
He removed the high places, and brake the images, and cut down the groves, and brake in pieces the brasen serpent that Moses had made: for unto those days the children of Israel did burn incense to it: and he called it Nehushtan. (2 Kings 18:4)
The universe is given to us to remind us of various things, some good, some not so good, because we need to be reminded of them.
And why stop there? A church building is not to be a museum of horrors or demonic creatures. Give it up.
