From what I understand the clearest guide from Christ himself says 2 things: love god and love your neighbor. Any of this other evangelical bullshit is heresy.
The pope didn't actually say the kids dad was in heaven but also Christians are supposed to "weep with those who weep" ie the pope should have comforted the kid in this situation anyway
Im not deep into christian lore but im pretty sure many rules and concepts are somewhat flexible and situational applied.
