A while back, I read a long article written by a U.S Army Chaplain - this is a U.S soldier who never carries a weapon, and main purpose with a unit is to pray for their safety in battle - no joke lol. Oh don't worry, they cover this insanity with a Chaplain's Assistant (starting to sound like WH40K!), a real soldier who's job is to protect the life of the Chaplain. The Chaplain, if captured by the enemy, has an obligation to try to escape - without killing anyone or carrying a weapon.
Most Western armies can't equip their Chaplains with weapons if they wanted to, because international law states that Chaplains should be non-combatants, in a sense.
But what I read today, something that I've been curious about - is whether priests have to report things in confessional that people report, that they should go to jail for. The answer is NO!
Yep, one exception to the secularity of countries is that Catholic priests, by religious law (this one the legal system recognizes), cannot report a crime that someone told them about in confessional. "I raped the girl and threw her into the drain..." "I killed my mother..."
You're forgiven!
