Christians today are not authorized to destroy images that belong to other people. But Deut. 7:25 and 26 outlines a command to Israel and provides a pattern as to how Christians today should view any images in their possession that they may have venerated:
"You must set fire to all the carved images of their gods, not coveting the gold and silver that covers them; take it and you will be caught in a snare: it is detestable to Yahweh your God. You must not bring any detestable thing into your house or you, like it, will come under the ban too. You must regard them as unclean and loathsome ["thoroughly loathe it and absolutely detest it," NW]." (Deut. 7:25, 26) JB
(Also see Acts 19:19.)
