For what I know the church “doesn’t like” that tradition but Is ok to go to a shrine on your knees till it bleeds… Help me understand.
Do you have a spiritual advisor? If so this is something you should be asking him and folow his advice. While not forbidden physical moritifcations like the above should really only be engaged in with the permission of ones spiritual advisor.
Actually I think it’s okay. Last Sunday we had a presentation from two women who went to Portugal, and to the Fatima Shrine with other members of our church in 2011, and they said many people from our church and other pilgrims walked the path to the shrine on their knees, and it was a very intense and holy experience.
