I’d like to respond to someone who publicly stated that he wished a specific group of named people would go to hell (and meant it, in a literal sense). My understanding is that we’re not allowed to do that. However, I have not been able to find any magisterial sources saying that we shouldn’t do it.
Catechism would suffice. Encyclicals would be better. Does anyone know where I can find a quotation that I can use to show him that this isn’t acceptable?
