Are you talking about those folks who will have themselves nailed to crosses and/or the ones who beat themselves bloody?The way they do this in the Philippines maked me run for the nearest air conditioned church.reenactments of the Passion
It was interesting when I was growing up in that country. We actually had a few men in the community who took "vows" to do the Passion during Holy Week. (Of course, none of them got nailed to the cross.) One man carried a heavy wooden cross over his shoulder every year from his village all the way to the town church, which was a good walk. Others were actually reenacting the Passion--Jesus Christ carrying a cross with a few Roman centurions on his side.
