After reading over these comments, here's my thought: Lighten up!

It's just a sign on a door. It's not an encyclical. It's not a synodal document. Are the battle lines really so tightly drawn that we now have to take sides on the words on the pope's door, fer cryin' out loud?

Some prig will likely point out that no previous pope had a sign on his door. That's true. You know why? Because nobody could ever get close enough to any previous pope's door to read a sign.

Francis chooses to live among other people. He chooses to have a goofy sign on his door. He's a person. Deal with it.
