I guess you learn something new every day. (At least for me that’s still the case.) Anyway, I was reading something or other and came across a mentioning of the Roman Catholic practice of putting salt in holy water. Strange. I was trying to learn more about it online and stumbled upon this forum thread on a site appropriately called Catholic Answers.
To begin with, the question was posed whether salt is needed. Or, more precisely, the person asked the priest to bless some more holy water as the holy water urn was being cleansed and she wanted it to be replaced with fresh water. When she told him that there was already salt added he told her that salt was unnecessary. To top it all off when he blessed the water she says, “he simply waved his hand in the sign of the cross over the urn and announced it was blessed”. Apparently, according to her, when their deacon usually does it he uses a “Book of Prayers and recites a beautiful prayer.”
Hence, now there are two issues: salted or unsalted/wave of hand or long prayer?
