The Israelites regarded Yahweh as their Father, as seen in verses such as Isa.63:16 (“You, O Yahweh, are our Father”) and Isa.64:8 (“But now, O Yahweh, you are our Father”). But to trinitarians, the Father is only the first person of the Trinity. Just as “Father” is not a proper name but a term that defines a relation to one’s own son, so in trinitarianism, God the Father has no name, but is defined in relation to the second person, God the Son, who ironically does have a name. His name “Jesus” is a very human name that was common in Israel in New Testament times
