Introduction

Monotheism is a form of religious belief and practice that centres on one God as the sole creator and ruler of the world. This type of belief is based on three primary works, the Old Testament of Judaism, the New Testament of Christianity and the Holy Quran of Islam. Monotheism has also been adopted by other religions such as Sikhism, Baha’i Faith, Zoroastrianism and Rastafarianism.

First introduced in ancient Mesopotamia around 2000 BC, monotheistic beliefs have become increasingly widespread throughout human history. The emergence of monotheistic faith is primarily attributed to Abrahamic religions which emphasize an all-powerful God who reigns alone over everything that exists.

Belief System in Monotheistic Religions

Monotheistic religions are those that recognize the existence of only one god. The belief system of these faiths involves a central figure or deity, and followers who are expected to adhere to certain behaviors and rituals in order to affirm their faith. This system places an emphasis on following teachings from religious texts, as well as communal worship and pilgrimage.

Monotheism is the cornerstone of many major world religions, including Judaism, Christianity and Islam. At the heart of each faith lies a set of core beliefs about God’s nature and humanity’s role within it. Monotheists strive for righteousness by adhering to specific codes or laws meant to help them act righteously in all aspects of life. Many believe in salvation through a divine saviour figure; while some focus more on spiritual enlightenment achieved through devotion and study.

Judaism

Judaism is one of the oldest monotheistic religions in the world. It is based on a set of beliefs and laws that are important for Jews to follow. These beliefs are found in the writings of the Hebrew Bible, which includes both written and oral traditions. Judaism is unique among monotheistic religions because it not only emphasizes faith but also encourages people to contemplate their religious views and put them into practice through devotional rituals and acts of charity.

The core belief system in Judaism revolves around a single God who created the universe, watches over His creations, and is present everywhere at all times. He alone should be worshipped and obeyed, as He sets down rules for living an ethical life that serves Him best. Jewish beliefs also include an afterlife where they will be rewarded for good deeds and punished for their bad deeds. 

Christianity 

Christianity is one of the world’s major monotheistic religions, and its adherents have a variety of fundamental beliefs. At its core, Christianity incorporates the idea that there is only one God who created all things visible and invisible. This singular deity, known as the Trinity or Triune God, comprises three distinct persons—God the Father, Jesus Christ his Son, and the Holy Spirit. The New Testament states that Jesus himself lived on earth in human form to bring salvation to humanity through his death and resurrection. The Christian faith encompasses several important beliefs concerning both spiritual matters and moral conduct.

Islam 

Islam is one of the most widely practised monotheistic religions in the world. It is a faith that has been embraced by over 1.8 billion people who strive to live according to its beliefs and teachings. Islam is based on five main pillars, which are known as the declaration of faith, prayer, charity, fasting and pilgrimage. These pillars form the basis of what it means to be a Muslim: believing in Allah and his messengers; performing regular prayers; giving charity regularly; fasting during Ramadan; and making an annual pilgrimage (Hajj).

Apart from these five pillars, Islamic beliefs include a belief in Allah’s absolute unity (Tawhid) as well as angels, jinns, prophets and holy books such as the Quran – which all  Muslims believe contains all knowledge necessary for living life according to divine guidance.
