Monotheistic in the context of "Zoroastrianism"

Late antiquity is a period of time that comes after the end of classical antiquity and stretches into the beginning of the Early Middle Ages, though the exact start and end dates are debated. Late antiquity represents a cultural sphere covering much of the Mediterranean world, including parts of Europe and the Near East.

Late antiquity was an era of massive political and religious transformation. Religiously, it marked the origins or ascendance of the three major monotheistic religions: Christianity, rabbinic Judaism, and Islam, as well as the period when both the Bible and the Quran were canonized. Politically, it marked the ends of the Western Roman Empire and the Sasanian Empire (the last Persian empire of antiquity), as well as the beginning of the Arab conquests and the formation of the Rashidun Caliphate. Meanwhile, the Byzantine Empire became a militarized and Christianized society. Late antiquity was also an era of significant cultural innovation and transformation, marked by the emergence of public architecture like the Hagia Sophia, and the emergence of late antique literature and art.

Christianity is an Abrahamic monotheistic religion, which states that Jesus is the Son of God and rose from the dead after his crucifixion, whose coming as the messiah (Christ) was prophesied in the Old Testament and chronicled in the New Testament. It is the world's largest and most widespread religion with over 2.3 billion followers, comprising around 28.8% of the world population. Its adherents, known as Christians, are estimated to make up a majority of the population in 120 countries and territories.

Christianity remains culturally diverse in its Western and Eastern branches, and doctrinally diverse concerning justification and the nature of salvation, ecclesiology, ordination, and Christology. Most Christian denominations, however, generally hold in common the belief that Jesus is God the Son—the Logos incarnated—who ministered, suffered, and died on a cross, but rose from the dead for the salvation of humankind; this message is called the gospel, meaning the "good news". The four canonical gospels of Matthew, Mark, Luke and John describe Jesus' life and teachings as preserved in the early Christian tradition, with the Old Testament as the gospels' respected background.

Islam is an Abrahamic monotheistic religion based on the Quran and the teachings of Muhammad. Adherents of Islam are called Muslims, who are estimated to number 2 billion worldwide and are the world's second-largest religious population, after Christianity.

Muslims believe that there is a primordial faith that was revealed many times through earlier prophets and messengers, including Adam, Noah, Abraham, Moses, and Jesus, and they believe that Islam is the universal and complete version of this faith. Muslims consider the Quran to be the verbatim word of God and the unaltered, final revelation. Alongside the Quran, Muslims also believe in previous revelations, such as the Tawrat (the Torah), the Zabur (Psalms), and the Injil (Gospel). They believe that Muhammad is the main and final of God's prophets, through whom the religion was completed. The teachings and normative examples of Muhammad, called the Sunnah, documented in accounts called the hadith, provide a constitutional model for Muslims. Islam is based on the belief in the oneness and uniqueness of God (tawhid), and belief in an afterlife (akhirah) with the Last Judgment—wherein the righteous will be rewarded in paradise (jannah) and the unrighteous will be punished in hell (jahannam). The Five Pillars, considered obligatory acts of worship, are the Islamic oath and creed (shahada), daily prayers (salah), almsgiving (zakat), fasting (sawm) in the month of Ramadan, and a pilgrimage (hajj) to Mecca. Islamic law, sharia, touches on virtually every aspect of life, from banking and finance and welfare to men's and women's roles and the environment. The two main religious festivals are Eid al-Fitr and Eid al-Adha. The three holiest sites in Islam are Masjid al-Haram in Mecca, Prophet's Mosque in Medina, and al-Aqsa Mosque in Jerusalem.

The Abrahamic religions are a set of monotheistic religions that respect or admire the religious figure Abraham, namely Judaism, Christianity, and Islam, though the term also often encompasses several smaller faiths. The religions of this set share doctrinal, historical, and geographic overlap that contrasts them with Indian religions, Iranian religions, and East Asian religions. The term, introduced in the 20th century, replaced "Judeo-Christian" to include Islam as an Abrahamic religion and acknowledge differences between Judaism and Christianity. However, it has been criticized for oversimplifying cultural and doctrinal nuances.

The Druze, who call themselves al-Muwaḥḥidūn (lit. 'the monotheists' or 'the unitarians'), are an Arab esoteric religious group from West Asia who adhere to the Druze faith, an Abrahamic, monotheistic, and syncretic religion whose main tenets assert the unity of God, reincarnation, and the eternity of the soul.

Although the Druze faith developed from Isma'ilism, Druze do not identify as Muslims. They maintain the Arabic language and culture as integral parts of their identity, with Arabic being their primary language. Most Druze religious practices are kept secret, and conversion to their religion is not permitted for outsiders. Interfaith marriages are rare and strongly discouraged. They differentiate between spiritual individuals, known as "uqqāl", who hold the faith's secrets, and secular ones, known as "juhhāl", who focus on worldly matters. Druze believe that, after completing the cycle of rebirth through successive reincarnations, the soul reunites with the Cosmic Mind (al-ʻaql al-kullī).
