Check out Susan's post and compare the pope's ferula (which differs from a bishop's crozier which is shaped like a shepherd's crook and is usually a ball with a cross) to the satanic stang. Hmmm....Sure looks like a stang doesn't it! Ann Barnhardt has a chilling article about the stang and the pope's use of it here. Of course the youth who gave it to the pope had a different explanation for it, (Surprise!) but that would be expected wouldn't it? The devil can appear as an angel of light.
And if he wondered about the item (which he certainly should), don't you think he'd ask one of his advisors what the symbolism of such a staff was? My first impression was that it was a divining rod which certainly has connections to divination and hidden, secret knowledge.
How can anyone not be concerned about this? Pray and fast and stick close to your guardian angel.
