Some claim venerating the Cross is idol worship - Did Jesus or the Disciples wear one?
The earliesr Christian symbos were a fish and were used by the apostles and early christians for identification, the cross came later
The fish was a symbol for identification. The early Christians were persecuted and had to know who to trust. The cross on the other hand is a cruel deadly instrument to inflict as much shame, pain and humiliation on a poor victim as possible. The Apostles knew about the cross but never wore it. They would have condemned anybody for this heinous jewelry.
