There is a part of either the First or Second Commandment that says:
“Thou shalt not make unto thee any graven image, or any likeness (of any thing) that (is) in heaven above, or that (is) in the water under the earth:”
Graven image is described as an object of worship carved; usually from wood or stone. It might be extended to other images with today’s technology, but I think the original made (carved) object gives a sufficient idea for this commandment, since that is what pagans did back then in worship.
An article by John Stapleton in the Catholic Encyclopedia on this site says:
“…: the making of ‘graven images’ is condemned; not all pictures, images, and works of art, but such as are intended to be adored and served.”
The “gold cherubim” defense in the “Here’s a clever post” does not hold much water, when you consider that those images were commanded to be made by God. I highly doubt that they were worshipped in any way, since they were not even seen by the people, except by the priests occassionally.
The question of obedience to the commandment described in Exodus 20:4-5 does still seem to require that no such objects be made or used as objects of worship.
