Who's they? That's a matter of discipline, not doctrine. Furthermore, in a Baptist church you'll find even less hope for discipline; actually none at all: there is no formal way to actually put down a heretical parish/congregation. There is no teaching on discipline, correction, and ecclesiastical punishment. In the Anglican context especially in orthodox jurisdictions like ACNA and the Continuing Churches, it is practically impossible to be a heretical parish and escape the ire of your bishop. When one recent ACNA church started getting a little friendly with TEC, the Archbishop publicly rebuked and condemned them even for that, before they did anything wrong. This would be impossible in the Baptist context where you'd have no recourse to any kind of discipline whatsoever. If you are hungry for better discipline toward godly doctrine, then you're more likely to find it in the Anglican context than anywhere else, in this weak world of today's 21st century Christianity.
