[Romulus]

Disobeying God is a mortal sin. Disobeying man is not.

What about when a man is authorised to speak for God? Being Catholic and all, surely you acknowledge this possibility.

[CobaltBlue]

When a man is authorized to speak for God, and you don't do what he says, the Person you're disobeying is God, not the man.

Duh.
