James 2:1-4,9 -- "My brethren, do not hold the faith of our Lord Jesus Christ, the Lord of glory, with partiality. For if there should come into your assembly a man with gold rings, in fine apparel, and there should also come in a poor man in filthy clothes, and you pay attention to the one wearing the fine clothes and say to him, "You sit here in a good place," and say to the poor man, "You stand there," or, "Sit here at my footstool," have you not shown partiality among yourselves, and become judges with evil thoughts? . . . but if you show partiality, you commit sin, and are convicted by the law as transgressors."
The key to the text you quote is the phrase "a poor man in filthy clothes." Like I said in at least one previous post, if the person can't afford, better, that is fine. But, in a church situation, where you know each other, and you KNOW the other person is NOT poor and they insist on dressing like a slob in G-d's house, it shows a lack of respect to the Holy Spirt, who is grieved by our disrespect; to the Messiah who gave His life for them and to His Father who is above all things.
That's gotta' be the best tag line I've read on FR ever.
