Has anyone done any digging on wearing the cross as a piece of jewelry?

A study of ancient history reveals that the cross was used as a religious symbol long before the first century A.D.—when Jesus Christ walked the earth, was crucified and resurrected. The Bible does not record the use of the cross as a physical religious symbol in either the Old or New Testaments. But historical records of other civilizations do make record of the cross as a symbol.

It is a historical fact that the cross has been used as a symbol of pagan religions going back to antiquity. Further study reveals that the cross can be found in the ancient religions of Babylon, India, Syria, Egypt, Rome and other ancient pagan cultures.

It is very clear, based on history, that the cross was used to represent and worship the false gods of many cultures and religions.

Many symbols have been taken over by the Cabal, Deep State, and elites over the years. Swastika and Spiral are two others.

If the cross was so bad upright, then why would the elites choose to worship Lucifer with the unside down cross?

You have a very good point! I know about the Swastika.
Is the pedo swirl the perversion of the spiral? I'll have to look into it. Thank you!

The upside down cross can also be the Icelandic and Nordic symbol of the hammer of Thor.
"During the Christianization of the pagan Scandinavian countries in the late tenth and early eleventh centuries, pagans wore Thors hammer necklaces and amulets to honor their original faith and reject Christianity. Archaeologists have found variations of the hammer pendant throughout Denmark, Sweden, Norway and Iceland. Even today Thors hammer remains a symbol of Norse paganism and neopaganism."

The upside down cross was also a symbol of faith for the early Christians. St. Peter, when crucified, requested of Nero that he be crucified upside down because he was not worthy to be crucified in the same manner as Christ.
