I'm obedient to the church; my bishops, the canons, the constitution and so forth. That doesn't mean I think every decision to which I'm obedient is right or the best possible decision.
I'd add, too, that there are areas where obedience is... routinely fudged. There's hardly a clergy person out there who hasn't broken their vow to use "a lawfully authorised form" [of service] "and none other."
If you've ever been to a service of lessons and carols, for example, you've been to a form of service which is not authorised. Yet if I were to ring my bishop and ask his permission to have one, he'd probably roll his eyes, because they're so embedded in the life of the church. Should we not have carols services, then?
