You quote so much, but what about the people that are in the news that are in church every Sunday, then go out and "break" so many of the commandments. Thou shalt not steal..Thou shalt not kill..Thou shalt now covent thy neighbors wife..
One example that I can think of right now, is fresh in the news, and also is connected to something that you mentioned..John Ensign, who is a prominate member of the promise keepers, has had, in his own admission, multiple affairs. And he is a "Christian".
I know many people that are true to their families, community, and the United States, that do not go to church every Sunday. In many people's eyes, this labels them as non-christians, because they do not attend a "church".
These may only be a couple of examples, but when people start touting that anything but "Chistianity" is what is causing the problems in America, when the founding fathers came here to escape "RELIGIOUS OPRESSION", just doesn't make sense.
But as always, this is a free country, and EVERYONE has the right to their own opinions and beliefs.
Sorry so long, just my .02.
Thanks and Have a Great 4th of July Weekend!!
