I agree with Ituralde: only the Chancellor can make moves on the campaign map, unless he specifically authorises another player (e.g. to pursue a defeated army). But what GH did was characterful and not against the Edicts etc, so let's play on. The respawning hostile Pope mechanic is a bit weird and it bound to lead to some rather unsatisfactory situations from a role-playing/realism situation until we can make peace.
