According to Deuteronomy 6:4 and Mark 12:29, Jesus affirmed that God is one, which disproves the concept of the Trinity and Jesus' divinity.

The argument begins by acknowledging that Jesus quoted Deuteronomy 6:4, affirming the oneness of God. However, this oneness does not specify the nature of that oneness. The Bible presents God as having multiple attributes and characteristics, indicating a complexity within His unity. Furthermore, both the Old and New Testaments reference multiple persons of God, suggesting that God's oneness is not merely a singularity in personhood but rather a unity in essence that encompasses a plurality. The Christian doctrine of the Trinity encapsulates this understanding, where God is one being in three persons: the Father, the Son, and the Holy Spirit. Thus, Jesus' affirmation of God's oneness does not contradict His divinity or the concept of the Trinity, but rather supports a deeper understanding of God's nature as revealed in Scripture.
