Muslims believe that the concept of the Trinity contradicts the oneness of God as presented in the Quran.

In the book of Daniel, we see a profound encounter that suggests a plurality within the Godhead. Daniel's vision of a being who looks like a man, described in rich detail, indicates that God can manifest in forms that are both divine and personal. This vision is not isolated; it complements the New Testament's revelation of Jesus Christ as the incarnate Word of God, who is fully divine and fully human. The complexity of God's nature is further supported by passages such as John 1:1, which states that 'the Word was with God, and the Word was God.' This indicates a relationship within the Godhead that is consistent with the concept of the Trinity. Moreover, the presence of heavenly beings, such as Michael, in Daniel's vision illustrates that God operates within a divine council, reinforcing the idea of a uniplural God. The Christian understanding of the Trinity does not negate God's oneness but rather enriches it, showing that God exists in a community of love and relationship. This is a critical distinction that highlights the depth of God's nature and His revelation to humanity. In response to the claim that the Trinity contradicts God's oneness, it is essential to recognize that the early church grappled with these concepts and arrived at the doctrine of the Trinity as a way to articulate the fullness of God's revelation in Scripture. The complexity of God's nature is not a contradiction but a divine mystery that invites deeper understanding and exploration.
