I do not think it is appropriate to drink holy water but some people do. Is it all right to drink it?
Answer by Catholic Answers on 1/29/2008:
It depends on who you ask. Some people see no problem with it. Others do. So far as I know, the Church doesn't forbid it. My personal opinion though is that holy water is intended for external blessings, that drinking holy water can easily become a superstitious practice, and that those who feel themselves in need of spiritual cleansing should go to confession.
