The Church was much more unified in his day. There wasn't even the East-West schism yet. There was the Church, and there were the schismatics.
My tagline is quite consistant with my lenient attitude. No matter how bad the Church screws things up, I am still loyal to her. No matter how screwed up a part of the Church may be - and believe me, there are some pretty messed up parts of the Church - they are still "the Church" if they teach Christ, his death and resurrection.
This is also consistent with my three-tier approach - the essentials as defined by the Bible interpreted through the lens of the Creeds; the doctrinal, as defined by my church's stnadards; and the personal. The deity of Christ belongs in the first, Calvinism in the second, and permissive use of alcohol in the third. The first establishes the outer bounds of what is Christianity, the second the type of Church I will affiliate myself with, and the third the practices I hold myself accountable to.
I take it from your post that you believe that the Reformation was not a necessity, but merely an unfortunate misunderstanding.
Can't we all just.... get along?
