Theism, in its most inclusive usage, is the belief in at least one
deity. Some narrower usages specify that the deity believed in be a distinct identifiable entity, thereby being contrasted with pantheism. Other narrower usages specify that the deity (or deities) be an active, immanent force in the universe, thus excluding some forms of deism. Theism can be categorized into more particular types, such as monotheism(in which case the word " God" is capitalized) and polytheism.
The term "theism" was first used by
Ralph Cudworth(1617-1688) [cite book|last=Halsey|first=William|coauthors=Robert H. Blackburn, Sir Frank Francis|title=Collier's Encyclopedia|editor=Louis Shores|publisher=Crowell-Collier Educational Corporation|date=1969|edition=20|volume=22|pages=266-267|language=English] ,and was probably coined to contrast with " atheism", a term that is attested from ca. 1587 (see the etymology section of atheism for details).
Divisions by numbers of deities
Monotheismis the belief that there is only one deity. [ [http://www.askoxford.com/concise_oed/monotheism AskOxford: monotheism ] ]
* Inclusive monotheism: The belief that there is only one deity, and that all other claimed deities are just different names for it. The
Hindudenomination of Smartismis an example of inclusive monotheism.
* Exclusive monotheism: The belief that there is only one deity, and that all other claimed deities are distinct from it and false — either invented, demonic, or simply incorrect. Most
Abrahamic religions, and certain versions of the Hindu denomination of Vaishnavism, such as ISKCONwhich regard the worship of anyone other than Vishnuas incorrect are examples of exclusive monotheism.The earliest known form of monotheism still in practice is Judaism.
Polytheismis the belief that there is more than one deity. [ [http://www.askoxford.com/concise_oed/polytheism AskOxford: polytheism ] ] In practice, polytheism is not just the belief that there are multiple gods; it usually includes belief in the existence of a specific pantheon of distinct deities.
Within polytheism there are "hard" and "soft" varieties:
Hard polytheismviews the gods as being distinct and separate beings; an example of this would be ancient Greek Mythology.
Soft polytheismviews the gods as being subsumed into a greater whole. Most forms of Hinduismserve as examples of soft polytheism.
Polytheism is also divided according to how the individual deities are regarded:
Henotheism: The belief that there may be more than one deity, but one is supreme.
Monolatry: The belief that there may be more than one deity, but only one should be worshiped.
Kathenotheism: The belief that there is more than one deity, but only one deity at a time should be worshiped. Each is supreme in turn.
Divisions by natures of deities
Forms of pantheism
Pantheism: The belief that the physical universe is equivalent to God, and that there is no 'division'. [ [http://www.philosophypages.com/dy/p.htm#pant Philosophical Dictionary: Pacifism-Particular ] ]
Panentheism: Like Pantheism, the belief that the physical universe is joined to God. However, it also believes that God is greater than the universe.
Forms of deism
Deismis the belief that a god or gods exists, created the world, but does/do not alter the original plan for the universe. [ [http://www.askoxford.com/concise_oed/deism AskOxford: deism ] ] It typically rejects supernatural events (prophecy, miracles) and divine revelation prominent in organized religion, along with holy books and revealed religions that assert the existence of such things. Instead, Deism holds that religious beliefs must be founded on human reason and observed features of the natural world, and that these sources reveal the existence of a supreme being as creator. [Webster's New International Dictionary of the English Language (G. & C. Merriam, 1924) defines deism as "belief in the existence of a personal God, with disbelief in Christian teaching, or with a purely rationalistic interpretation of Scripture..."]
Pandeism: The belief that God preceded the universe and created it, but is now equivalent with it.
**Panendeism combines deism with panentheism, believing the universe is a part (but not the whole) of deity
Polydeism: The belief that multiple gods existed, but do not intervene with the universe.
Misotheism: the belief that some god or gods are evil.
