If Jesus was truly Yahweh (God) in the flesh, why didn't any of his disciples call him by the name Yahweh? Why wasn't Jesus referred to as Yahweh by any the apostles if he was truly Yahweh (God) in the flesh?

 The concept of the Trinity in Christian theology teaches that God exists in three persons: the Father, the Son (Jesus Christ), and the Holy Spirit. The idea is that these three persons are distinct but share the same essence or nature. Therefore, while Jesus is considered to be divine in Christian belief, the title "Yahweh" is traditionally associated with God the Father in the Old Testament.

In the New Testament, the disciples and early followers of Jesus recognized and proclaimed his divinity but did not explicitly use the term "Yahweh" to refer to him. Instead, they referred to Jesus as the Son of God, the Messiah, or Lord. The term "Lord" was a common way to address Jesus, signifying his authority and divinity.

It's important to note that the theological understanding of the Trinity evolved over time within Christian traditions. Early Christians, particularly in the first few centuries, grappled with articulating the relationship between Jesus and God the Father. The specific language and terminology used to describe the Trinity, including the use of "Yahweh" in relation to Jesus, were formulated in later theological discussions and councils.

In summary, the disciples and early followers of Jesus acknowledged his divinity but didn't use the term "Yahweh" specifically for Jesus in the way it was traditionally associated with God the Father in the Old Testament. The development of precise theological language and terminology took place in the centuries following the events described in the New Testament.
