The term "people of faith" generally includes all people who believe in God based on faith. The largest portion of these people of faith belong to one of the three Abrahamic "revealed" religions. The big three Abrahamic "revealed" religions are Judaism and its two offshoots of Christianity and Islam.
All three are based on belief in the ancient Hebrew Abraham. They teach that Abraham had a special covenant with God and that Abraham is the patriarch of their particular "revealed" Abrahamic religion.
The Jews claim God revealed his will in the Hebrew Bible/Old Testament while Christians claim God's will is revealed in both the Hebrew Bible/Old Testament and in the New Testament. Muslims believe God revealed his will in the Hebrew Bible/Old Testament as well as in the New Testament and that he gave his final revelation in the Koran. Hence, all three are "revealed" religions, that is they all claim to have their religion based on a revelation from God.
The reason people who believe in Judaism, Christianity and Islam are all considered to be people of faith is because there is no logical way for them to believe their scriptures are divine revelations. The American founder and Deist Thomas Paine clarified this fact in his monumental book on God, Deism, religion, etc., The Age of Reason, The Complete Edition (for Kindle version click here). Paine writes, "Revelation, when applied to religion, means something communicated immediately from God to man.
"No one will deny or dispute the power of the Almighty to make such a communication, if he pleases. But admitting, for the sake of a case, that something has been revealed to a certain person, and not revealed to any other person, it is revelation to that person only. When he tells it to a second person, a second to a third, a third to a fourth, and so on, it ceases to be a revelation to all those persons. It is revelation to the first person only, and hearsay to every other, and consequently they are not obliged to believe it.
"It is a contradiction in terms and ideas, to call anything a revelation that comes to us at second-hand, either verbally or in writing. Revelation is necessarily limited to the first communication - after this, it is only an account of something which that person says was a revelation made to him; and though he may find himself obliged to believe it, it cannot be incumbent on me to believe it in the same manner; for it was not a revelation made to me, and I have only his word for it that it was made to him."
Politicians of both the right and left
pander to people of faith. For example, when Hillary Clinton was
running for the Democratic nomination for President she said,
"I think the whole Bible is real." Also, Obama has been busy tearing down the wall of separation of government and religion with his White House Office of Faith-Based and Neighborhood Partnerships. Politicians on the right are
very open about their deep belief that the Bible is the word or
revelation of God.
Since so many people believe the Bible to be a revelation from God, it is important for them to objectively ask themselves some questions about what they believe in the Bible. Especially people like Hillary Clinton who believes "the whole Bible is real."
