Specifically I'm thinking about the fact that putting the ashes on the foreheads is correctly termed "Imposition of the ashes."
Why not "Applying of the ashes?" Or "Distributing of the ashes?" "Dusting of the ashes?" "Putting on of the ashes?"
An imposition is generally a negative thing. We don't like to impose on people. The government imposes taxes on us. Someone asking us to give them a ride in our already full car can be an imposition.
So why is this act of applying ashes an imposition?
Because it is a reminder of our sinful nature? Because it is a reminder of our mortality?
Isn't death the greatest imposition of all?
I think it's an interesting choice of words. If anyone knows why this terminology is used, I would love to know, too. If you have any thoughts about what that word means to you, I would love to hear that, too.
