Not a good precedent, even if well-meant.
I would LOVE to see some/any imam in the Vatican. WHAT a crushing blow to Islam.
In the Umayyad Mosque in Damascus, which we visited in the early-mid 1980's, there is a very large and ornate holder, which, it is said, holds the head of St. John the Baptist.
From Google: Sheltered inside the mosque is the small chapel and shrine of John the Baptist (Prophet Yahia to the Muslims) where tradition holds that the head of John the baptist is buried. One legend says that when the church was demolished, his head was found underneath, complete with skin and hair. This head is believed by some to possess magical powers and continues to be the focus of the Mandaeans' annual pilgrimage, when they press their foreheads against the metal grill of the shrine and reportedly experience prophetic visions.
What I saw there was the shrine, a very large, tall, beautiful and ornate holder--of St. John's head--and a circle of a half dozen imams (or so) around the shrine. These holy men PRAY there (changing shifts, of course) 24/7 because the Muslims considered St. John a very holy man.
They have been doing that for centuries.
Well meant? It is stupidity.
What the hell is wrong with this person?
