Do you want a "thy" with that?

As I have been working on more “theological translations” of some
older prayers a brief conversation with a friend has kept popping up in
my mind:

“I find as I try to encourage people to read and learn ancient prayers that the thees, thous and thys are enough to discourage people from ever considering it.”

“Yes, but on the other hand, there are those who relish the ancient character of prayers so much that to remove the thees, thous and thys is sacrilegious.”
