Jesus preached to worship One and Only God, not the Trinity.

Shahid misunderstands the doctrine of the Trinity, which asserts that God is one in essence but exists in three distinct Persons: the Father, the Son, and the Holy Spirit. This concept of 'tri-unity' does not negate the oneness of God but rather affirms it. When Jesus refers to the oneness of God in Mark 12:29, he is not denying his own divine nature but rather emphasizing the foundational truth of God's singularity. Furthermore, in the same chapter, Jesus distinguishes himself from the prophets, indicating his unique status as God's beloved Son and Heir, which supports his claim to divinity. Additionally, in Mark 12:35-37, Jesus quotes David, who, speaking by the Holy Spirit, refers to the Messiah as 'Lord.' This implies that the Messiah is greater than David and thus possesses divine authority. Therefore, when we consider both the oneness of God and the exalted status of Christ as presented in these passages, it becomes clear that Jesus claimed to be God, fulfilling the role of the one true Lord.
