It certainly is, to me.
Just as I show some degree of reverence for the printed Word of God . . . though I still mark the pages up etc.
And I don’t even begin to worship either a cross or a Bible.
I once did get close to idolatry of the Bible, but The Lord brought me up short about that.
Symbols can be useful. They can be hazardous. The attitude of the heart, imho, is crucial.
I prefer a kind of reverence for THE TRUTH OF THE CROSS . . . not per se any physical representation of it.
Though I would take care to protect a cross or treat it with respect OUT OF RESPECT FOR THE TRUTH OF THE ORIGINAL CROSS.
If I had to break up and burn a cross to feed a starving child a hot meal and warm them a bit, I would not hesitate more than a few seconds.
Truly I would not go ballistic over needing to retire a cross or a Bible, though I confess to keeping all of them. I specifically collect the deceased family member's Bibles (with lots of notes and inserts), wall crosses, cross jewelry, rosaries and such - all for any future generations who might want to remember what was important to them in this life.
But none of it is to be worshiped.
The symbols are important though to me. I would not use the wall crosses to aerate my potted plants.
