like all men with a calling from God, i think he is respectful and concerned with building harmony in the Spirit among all true belivers. but he’s not afraid to preach the Truth to all. he’s saying don’t be decieved to the Body while preaching the unvarnished Truth to God’s lost sheep.
and yes, no earthly church is perfect. i think i have met (like Graham) a bunch of true believers residing in that denomination and others. i think Pastor Graham wants to call out the best in all of us Christians. he wants to emphasize unity in the Body. may God continue to bless him with courage and strength to stand up for us against the enemy.
It is ironically by sticking to core evangelical principles of belief, that trust on Jesus Christ personally for eternal salvation will be rewarded with just that result, that I can see past a lot of the theological troubles of other segments of Christendom (and even in the evangelical segment). I wish the troubles were not there, of course, but they do not cancel out the promise.
