Maybe this will help. These are the Articles of Reason I have drawn from my beliefs.
Although I cannot speak for all Deists, I think this explains the beliefs of modern Deism very well.
1. Human beings are endowed by their Creator with the ability to Reason.
2. Reason and Natural Law lead us closer to the truth.
3. Reason leads us to believe in one God, or Prime Mover, who began Creation, and let Creation follow its own path, according to Natural Law.
4. Reason leads us to believe that all Human Beings are equal, regardless of race, origin, gender, or sexual preference.
5. We owe it to ourselves, as Reasonable beings, to act morally towards one and other.
6. God works within the realm of Natural Law, “miracle” and “revealed revelation” does not fit within Natural Law or Reason.
7. We owe it to ourselves, as Reasonable beings, whose very existence is dependent upon Natural Law, to be thoughtful caretakers of this world.
8. God, through Natural Law, gave us life. Reason leads us to believe that our purpose in life should be to live life to the fullest, and to ensure that all are provided the opportunity to do so.
9. Natural Law gives us Freewill. Predestination is contrary to Natural Law and is not Reasonable.
10. There is no “True Path”. As Science and understanding of our Natural world evolve, so too will our understanding of God.
