Revelation 17:4 “The woman was arrayed in purple and scarlet, and adorned with gold and precious stones and pearls, having in her hand a golden cup full of abominations and the filthiness of her fornication.”
“The color for bishops and other prelates is purple, for cardinals scarlet… The pectoral cross should be made of gold and… decorated with gems…”

The apostate papal church is adorned with gold, precious stones, and pearls; which we can clearly see in how the Pope and St. Peter’s Basilica are decorated.
