Muslims believe that the concept of the Trinity is incompatible with the strict monotheism of Islam, which emphasizes the oneness of God.

The New Testament presents Jesus Christ as the exalted Lord who sits at the right hand of God, as seen in Psalm 110:1. This position of authority is further affirmed in the Gospel of Matthew, where Jesus is depicted as the Son of Man coming in glory to judge the nations. The binitarian nature of God is illustrated through the unity of the Father and the Son, as they share divine authority and eternal dominion. Furthermore, the Book of Revelation reinforces this by portraying Jesus as the one seated on the cloud, symbolizing His divine kingship and eternal reign. Additionally, the identification of Jesus as the 'Son of Man' in Daniel 7:13-14 and His role in the eternal kingdom emphasizes that His divinity is not separate from God's oneness but rather a part of the divine revelation. The Christian understanding of God encompasses both His unity and the relational aspect of the Father and the Son, which is consistent with the monotheistic framework of the Old Testament. In light of these scriptural affirmations, the Christian belief in the binitarian nature of God does not violate the principle of monotheism but rather enriches the understanding of God's nature as revealed in both the Old and New Testaments. This perspective invites a deeper exploration of the relationship between God and Jesus, showcasing how the New Testament fulfills the monotheistic claims of the Old Testament.
