These days it seems that the vast majority of people I run into that claim to be Christians simply are not..
What are they anyway?
Simply a person who attempts to live a good life? Really, this is a pathetic definition of the most apologetic variety, in such a case every religion and even the irreligious (of which I count myself as one) contain Christians. I think for now this type definition can be dismissed as so watery it has lost all import. There is also the logical back-step (modus tollens) that those who are not Christians are not trying to live a good life. This section make up most of the people that want to argue with an Anti-Theist, for the life of me I can not understand this as they ought know they are simply to pathetic to argue with. I liken this to the spiritual person who wishes to argue for the existence some sort of intangible ethereal energy of some kind, it is impossible to argue against something so lacking, so why bother.
Maybe someone whom dogmatically believes in God, the Christ and the life ever-after? This is I think the weakest definition one ought to accept as being worthy of discussion.
Or is it the person that believes that the bible is the unalterable and unfalsifiable word of God, that gives total acceptance of a vast conglomerate of creeds set out with the greatest exactitude imaginable, and as such lives their life in every tiny detail according to it? What we are talking about here are Crusaders, or let us face it the Christian equivalent to the Muslim Jihadists we see on the news these days.
