This souns like something out of an Iranian Shiite ritual, not a CHristian ceremony.
These people are wacked!!
Though the Roman executioners gave Jesus and other Jews when they were crucified back their garments to satisfy Jewish religious codes of modesty and to not cause riots, persons in other Roman providences (such as the early martyrs like St. Peter) would have been crucified naked. Their hands would have been nailed at the wrists and their feet at the ankles against each side of the cross with the knees slightly bent to produce more agony whey the muscles of the chest began slowly asphyxiating the crucified and caused him/her to struggle to stand and relieve pressure. For crucified men, usually their genitalia was also nailed to the cross so when they stood it would rip. Crucified persons usually lasted only about a half of day of torture but those who went longer, all the better. And, if the executioners were in a hurry to get it over with, they broke the legs of the crucified so that they could not stand to relieve pressure--this was done to the thieves on the cross with Jesus as sundown was approaching but not to Jesus as He was already dead.
