“Many powerful people don’t want peace because they live off war. This is serious. Some powerful people make their living with the production of arms. It’s the industry of death.” ~Pope Francis (source)
Popes have done this all of my life.
They’re against war in general, but have never come out against a specific war. They have never once said, “If you are Catholic, you have to sit this one out.”
You can’t use birth control, you can’t get a divorce, and Lord help you if you’re gay; but if you want to take a gun and kill somebody, they won’t stand in your way.
They might even wave their flags and cheer as you go marching past.
