This is a great lecture/sermon by Mark Driscoll on the Church and what it means to be a congregation within the Church. I do not agree with all that Driscoll says but I think it is worth listening too and thinking about. I encourage you to listen to the whole thing.
I have only one correction: Mark Driscoll seems to be referring to the extreme catholic wing of Anglicanism. Reformed Anglicans (Good Shepherd included)do not think, nor to the Articles of Religion teach, that the Church resides wherever there are bishops. Rather the visible Church is present where the pure Word of God is preached, the Sacraments given according to Christ's institution and godly discipline is exercised.
Reformed Anglicans hold the apostolic succession of apostolic teaching to be primary--over and above the succession of bishops.
