[3] They, alongside Samaritanism, Druzism, the Baháʼí Faith,[3] and Rastafari,[3] all share a common core foundation in the form of worshipping Abraham's God, who is identified as Yahweh in Hebrew and called Allah in Arabic.
[1] God is typically referred to with masculine grammatical articles and pronouns only,[1][12] and is further held to have the properties of holiness, justice, omnibenevolence, and omnipresence.
[4][28] God in Judaism is conceived as anthropomorphic,[4][26][30] unique, benevolent, eternal, the creator of the universe, and the ultimate source of morality.
[4][32] Christianity originated in 1st-century Judea from a sect of apocalyptic Jewish Christians within the realm of Second Temple Judaism,[33][34][35][36][37] and thus shares most of its beliefs about God, including his omnipotence, omniscience, his role as creator of all things, his personality, immanence, transcendence and ultimate unity, with the innovation that Jesus of Nazareth is considered to be, in one way or another, the fulfillment of the ancient biblical prophecies about the Jewish Messiah, the completion of the Law of the prophets of Israel, the Son of God, and/or the incarnation of God himself as a human being.
[17][30][33][34][38] Most Christian denominations believe Jesus to be the incarnated Son of God, which is the main theological divergence with respect to the exclusive monotheism of the other Abrahamic religions: Judaism, Samaritanism, the Baháʼí Faith, and Islam.
[44] A small minority of Christians, largely coming under the heading of Unitarianism, hold Non-trinitarian conceptions of God.
The Quran prescribes the fundamental transcendental criterion in the following verses: "The Lord of the heavens and the earth and what is between them, so serve Him and be patient in His service.
[53][54] Muslims believe that Allah is the same God worshipped by the members of the Abrahamic religions that preceded Islam, i.e. Judaism and Christianity (29:46).
[55] Creation and ordering of the universe is seen as an act of prime mercy for which all creatures sing his glories and bear witness to his unity and lordship.
[56][57][58] The writings of the Baháʼí Faith describe a monotheistic, personal, inaccessible, omniscient, omnipresent, imperishable, and almighty God who is the creator of all things in the universe.
[61] Though transcendent and inaccessible directly,[62]: 438–446 God is nevertheless seen as conscious of the creation,[62]: 438–446 with a will and purpose that is expressed through messengers recognized in the Baháʼí Faith as the Manifestations of God[60]: 106 (all the Jewish prophets, Zoroaster, Krishna, Gautama Buddha, Jesus, Muhammad, the Báb, and ultimately Baháʼu'lláh).
[62]: 438–446 The purpose of the creation is for the created to have the capacity to know and love its creator,[60]: 111 through such methods as prayer, reflection, and being of service to humankind.
[63] God communicates his will and purpose to humanity through his intermediaries, the prophets and messengers who have founded various world religions from the beginning of humankind up to the present day,[60]: 107–108 [62]: 438–446 and will continue to do so in the future.
