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.
Have you ever written down what you’ve found in the Bibles? I know that would be appreciated by future generations. I’m writing my family history for that reason. It’s very interesting.
