The word was left for you

Exodus 20:2
You shall not make for yourself a carved image, or any likeness of anything that is in heaven above, or that is in the earth beneath, or that is in the water under the earth; you shall not bow down to them nor serve them. For I, the Lord your God, am a jealous God, visiting the iniquity of the fathers on the children to the third and fourth generations of those who hate Me, but showing mercy to thousands, to those who love Me and keep My Commandments.
Some Christians hold that the Cross/Crucifix in churches is a graven image, which it often is or possibly a cast or molten image and so you should not bow down to them.

This implies the hall of worship should be empty of any and all graven images.

If you follow this logic it implies we should not have them. This is the Why and How some of us stopped having crosses or any other graven image in churches.
