Secular history shows an Apostle cross was worn by the very early-1st generation apostles and Christians. Esp. In OS churches est by the Apostles. The converts were so enthusiastic to witness the good news. The Gospel! Even in Rome where they were punished and murdered for refusing to give up their love for Jesus. It was made.by almost anything. Wood and twine etc. It was NOT an idol but an opportunity to tell others what it was when asked.
I wear this one. It represents to me the humility of a Christ like person. I witness the same way.
