Obviously I also wasn't clear when I said that my comment was my own personal opinion.I suppose this thread is getting dangerously off topic, but I should like to respond to your final paragraph. You have created a semantical issue regarding the term Chriatian. All Catholics consider themselves Christian, as do adherents of the Greek Orthodox, Baptist, Methodist, Episcopal, Presbyterian, Nondenominational, and many other persuations. Yet you wish to restrict the term Christian to those who adhere to a particular version of Pauline theology. Were there no true Christians before Saul of Tarsus had his famous epileptic fit on the road to Damascus and thereafter formulated his theology and enlightened the world on the 'true' meaning of the Christ-event? I should think that the concept of salvation by grace through faith (i.e., Christianity) would not be so exclusive. But what do I know?
I think you may be taking this verse out of context, it's easy to do. God is talking about once a man is saved. They can't just get saved and have faith in God to trust that He will keep them saved, they have to "work" to maintain their salvation-read the Bible, go to church, lead a holy life before others, etc.James 2:24. "Ye see then that by works a man is justified, not by faith only."
