Ty 4 posting and also for the link:
Years ago I first met Ruth, she was at that time 102 years old, and frequently went to Eucharist Adoration (where I was a regular).
She gave me a very old Catholic pamphlet which spoke about the mysteries of Holy Water.
I learned that (like most any thing else) Sacramentals are limited in power only by the disposition of the supplicants who used them.
Anyway, the older generations of the faithful taught us that a sprinkle of Holy Water could be transferred into all people, living or dead.
I bought a Holy Water font, and to this day, I renew my Baptismal vows every day - the font is in front of my door - EVERY day before I step out into my little town - I ask God’s blessings for people who have nobody to pray for them or with them, etc.
