Deism has at minimum these attributes:
1. Belief in the existence of God, omnipotent Creator.
2. Belief that God can be understood and followed by reason alone
3. Follows a moral code derived from reason
4. Denial of ceremony, ritual, mysticism, special revelation (like the Bible), miracles or any kind of interventions by God to affect outcomes in the material world.
While Christianity and Deism are different belief systems, some called themselves "Christian Deists" to avoid the charge of heresy while believing as strict Deists, others adopted aspects of Christianity as it suited them (or vice versa).
