Even objects correctly identified as being used for religious rituals are often still derived from practical objects, whether cups, spoons, etc, or ritualized weapons. Few objects are purely religious in their derivation.

Sometimes the distinction between ritual and practical use is absolute, i.e "the sacred chalice shall only be used for services", or sometimes sacred vs. profane is distinguished by timing, or the incanting of particular verses.

In general, we have an overly dualistic view ("it is one or the other") of of the sacred and profane as pertains to ancient objects, perhaps influenced by the dualities pervasive in Western philosophical systems.
