WHAT I DON'T UNDERSTAND is, if Holy Water has all the properties usually attributed to it, why isn't one of them the ability to resist disease? I ask this as a simple seeker after truth. Having been brought up as a Catholic (now long since lapsed) I always believed that Holy Water, and indeed other blessed things, had almost magical abilities, though in what direction, I couldn't say.
We still have a bottle of Holy Water in OUR house, retrieved after the death of my parents and the subsequent sale of their house, though this one does say 'Leeds' on it. Hardly a souvenir.
Amazon sells Holy Water fonts for home use... what more is there to say?
What I think I'm coming to is that, even as a child, terrified of eternal damnation - I seem to have spent most of my childhood/adolescence in that state, (nuns have a lot to answer for) I'm not sure I had any better idea then than I do now, what properties the act blessing water, or a rosary or missal, etc. was supposed to convey to the inanimate object being blessed. I am now a non-believer (except in humanity) but even then, at my most fervent, I was mystified. Perhaps that's the point?
Holy water for the faithful to take home with them (St Teresa's church, Clarendon Street, Dublin)
"Once blessed, more ordinary water can be added to the supply of holy water, and the entire quantity of water remains blessed provided that the amount added is less than the amount of water that was there." http://en.wikipedia.org/wiki/Holy_water#Rituals_and_uses_of_holy_water
