When I was a student I remember having to put up with loud pop music on nights when I could have got a good night's sleep. When I was in the Church of the Holy Sepulchre in 1976, the Franciscans had the habit of playing their organ at full volume during the Divine Liturgy. I don't recall whether the door was open or not. I heard about this harassment when I was a child, how someone cut of a piece of carpet belonging to the Franciscans because it protruded into the Orthodox area etc..or was it the other way round?
Very sad to read the latest news. Helps us to rememer that we are human and subject to zeal not according to knowledge. Fanaticism is not always accompanied by fist fights.
