Thanks for the reply, Milo.
A significant structural difference between our two churches is that in the Anglican Church local bishops (and synods) have much more decision making autonomy that way than do their peers in the Catholic Church. The Catholic Church is structured more like an old time, centralised, absolutist monarchy. Only the Vatican has the authority to enact Canon law. Once it enacts enacts one the entire Church globally is bound by it and no local power can renounce or alter it.
