Please bear with me if I'm a little dense today (I had to work all last night and was up for almost 24 hours straight, so am a little slow today). Could you give me a little more clarification on your position? I read the referenced scripture and am familiar with it, but I'm not sure if I understand if you are defending the Catholic church with that, or if you were agreeing with my statement (you probably were clear, but I'm just missing it today).
To put it briefly, my point was that what you describe is exactly the Church that Jesus told us to expect, warts and all. And you'll note that when Jesus talks about a "chief steward" who "drinks and abuses the servants," he doesn't add "and you should separate yourselves from him quickly, because that isn't 'the Church' anymore, 'the Church' has moved to Grace Bible Fellowship down the street." He says that "that servant will be cut in two and his portion appointed among the unbelievers".
The tares, sown by the enemy, which grow amidst the wheat aren't just a figure of speech.
