The Christian tradition believes in a monotheistic personal God who has had a unique presence in Jesus Christ. We truly care to live with the mysterious life of God who has an impact on our lives. The God of Israel was Yahweh, whom the Christians consider God the Father. There is also the presence of the Holy Spirit, the Spirit of Yahweh, that is present in our lives. Jesus is the Son of God, the Father.
Monotheism that maintains that there is only one transcendent God. The Israelite belief in Yahweh, their one God, was the prime example of monotheism. Islamic faith with its belief in one God, Allah, is another later example of monotheism. Christianity took from Judaism its monotheism, but changed the Yahweh monotheism into a triune God of Father, Son and Holy Spirit.
The Old Testament Hebrew Bible raises questions of interpretation for a Christian. To what extent am I, as a Christian, projecting Christian views and values on the children of Israel, the people of Israel, the Israelites? There are various terms that translators have used to describe the slowing forming group of Yahweh believers over three thousand years ago. Yahweh was their God and intervened in their lives. They had a special relationship or covenant with him. The Hebrew sacred writings were incorporated into Christianity because all the early Christians were Jewish. However, the writings were not originally meant for Christians, but for the Hebrew people. Can I really fully understand the Semitic thought process of three thousand years ago? Will I be able to appreciate how important the promised land of Israel was to Jewish people? What role did the exodus from Egypt, the Temple, the exile, and the various codes play in their lives? I can try, but I doubt if I will be fully successful.
The later prophets are what we normally think of as prophets. They stood out against authority and asked people to reform their ways to that of Yahweh, their God. They were writing prophets, as opposed to the early prophets who did not write, but were written about. These later prophets are normally divided into the three major prophets and the twelve Minor Prophets. There were three famous major writing prophets whose works are very long. Isaiah lived in the 8th century BCE, but his work was not finished until around the 6th century BCE. On the other hand, Jeremiah and Ezekiel were 6th century BCE prophetic writers around the time of the Babylonian Exile.
