In perpetuity

A note to Chris Cadelago, which would normally be a tweet, but it's too long...

The Denver Post's motto is now "Voice of the Rocky Mountain Empire" but it used to be a bit more grandiose. Here it is:

Dedicated in perpetuity to the service of the people, that no good cause shall lack a champion and evil shall not thrive unopposed.

I used to use it on my Facebook page, but it seems to have disappeared in the "timeline."
