Early Christianity, as reflected in the New Testament, was not strictly monotheistic in the sense that later Nicene theology would articulate. Rather, it displayed a henotheistic or monolatrous worldview, in which one supreme God was worshiped as ultimate, yet other divine or semi-divine beings existed and could act or even be worshiped in a limited sense. This framework is evident throughout Scripture. Jesus, for example, cites Psalm 82:6 in John 10:34–36, referring to certain beings as “gods” in defending his own claim to divine sonship, showing no awareness that such language might violate monotheism. Paul similarly acknowledges multiple divine figures in 1 Corinthians 8:5–6, distinguishing the one God from other “gods” without framing their existence as problematic. The Book of Revelation also illustrates this henotheistic cosmology. In passages such as Revelation 11:15–19 and 19:11–21, God and the Lamb co-act in heaven with no apologetic justification, reflecting a worldview in which multiple divine powers could coexist under one supreme God. Other texts, including references to angels, Wisdom, the Logos, and the Son of Man, depict subordinate divine figures acting as agents of God, further demonstrating that early Christianity accepted a plurality of spiritual beings without perceiving any conflict with worship of the one God.
Neither the Hebrew Scriptures, the teachings of the apostles, nor the inspiration of the Holy Spirit in the earliest churches imposed the kind of strict monotheism later associated with Nicene orthodoxy. The earliest Christian communities freely referenced “gods” and divine agents, and there was no apologetic concern about violating monotheism. Revelation’s portrayal of God and the Lamb acting together without any defense of Christ’s divinity illustrates that early Christians lived comfortably within a henotheistic framework. Apostolic teaching focused on the supremacy of the one God revealed in Christ and on ethical and salvific instruction, rather than on formally defining the unity of God in philosophical terms. In this sense, the precise and rigorous monotheism codified at Nicaea was absent in the first centuries of Christian thought.
The emergence of strict monotheism in Christian theology likely arose from post-Temple developments in rabbinic Judaism. After the destruction of the Temple in 70 CE, Jewish leaders increasingly formalized monotheism, rejecting the idea that any other divine hypostasis could be worshiped alongside God. Claims that a heavenly figure might share divine status were condemned as heretical, forming the basis of the “Two Powers in Heaven” polemic that targeted Christian claims about Christ. Christian apologists and Church Fathers such as Justin Martyr, Athenagoras, Tertullian, and Origen were aware of these critiques and felt the need to defend Christ’s divinity while upholding the unity of God. The pressures of debate and the desire to maintain credibility in interactions with Jewish scholars and students encouraged Christians to clarify theological language and to avoid any appearance of polytheism. Greek philosophical concepts, including the notions of ousia(essence) and hypostasis (person), were subsequently employed to systematize these ideas and articulate a coherent relationship between the Father, Son, and Spirit. In this sense, strict monotheism in Christian thought was not directly derived from Scripture or apostolic teaching, but developed in response to post-Temple rabbinic monotheistic strictness and the intellectual and social milieu that accompanied engagement with Jewish thinkers.
Taken together, the evidence suggests that early Christianity began with a henotheistic worldview inherited from Second Temple Judaism. Scripture and apostolic teaching accommodated subordinate divine figures, and early Christians were comfortable within this framework. The precise, rigorous monotheism that would later characterize Nicene orthodoxy emerged not from these original sources, but as a response to post-Temple rabbinic critiques and debates, as well as the social and intellectual context in which early Church Fathers operated. These pressures prompted Christian thinkers to refine their articulation of God’s unity, defend the full divinity of Christ, and eventually formulate the theological structures that culminated in the Nicene Creed.
