Monotheism is a belief system in which there is only one God. Monotheists adhere to the Christian faith and believe that the deity is one. They believe God appeared to the human race as a father or Lord Jesus Christ and the Holy Spirit. Monotheists believe that if one is not practicing monotheism, they do not enjoy the protection of God.
Religions that believe in one deity
Monotheism claims that there is only a single god. It is the basis of many world religious systems. It differs from polytheism and atheism, which each attribute responsibility for reality to a separate god. Monotheistic religions believe that God is all-knowing, all-powerful. They are usually non-anthropomorphic.
Some religions are dualistic, which means that the universe is split into two basic principles: spirit and matter. This is a variation on monotheism found in some of the gnostic systems. These religions are founded on esoteric wisdom and are sometimes deemed heretical for orthodox Christians. The demiurge can be described as a demonic entity.

Many of these religions have sacred books that guide their lives. The most prominent of these texts are the Christian Bible and the Hebrew Scriptures. Some religions believe the texts were directly written by a god, while others believe they were written from humans. In Oromo, for example, the single god is called Waaqeffanna, or "the word."
Religions that are quasi-monotheistic
Religions that are quasi-monotheists have some similarities to true monotheism, but there are differences. True monotheism emphasizes that there is only one god, and that all the others are illusions. Quasimonotheism emphasizes the importance of God in all aspects human life.
Monotheism and its application in religion have their roots in the early modern period. The term was coined by Henry Moore in 1660 to distinguish between Christian anthropomorphic conceptions of God and Deistic concepts. Later, the term "monotheism," was used in conjunction with "polytheism", another concept that was created in the first century CE.
The ancient Greeks and Romans had monotheistic religions, and they believed in a supreme god. Zeus' worship was a sign of the transition from polytheism into monotheism. The veneration of Zeus reduced the respect shown to lesser gods.

Monotheistic religions
Monotheistic faiths believe only one god. While polytheistic beliefs believe in many gods, they are called monotheistic. Monotheism is rooted in the Old Testament Hebrew Bible. Other gods can be called "false Gods". Later Christianity and Judaism stressed the concept of one god.
Monotheistic religions are those that believe only in one God. They reject all other beliefs and systems. As such, they are often aggressive and justify their actions with the claim that their religion alone is true. In many instances, they have also used monotheism as a means to justify the behavior of other people, which is incompatible with the message of the religion.
Many gods were worshiped in ancient cultures, but one god was not unusual. In fact, some ancient civilizations even elevated a single god above all other gods.
