@hearkat, the use of certain other names and titles for God is part of the religious custom and practice of the Jews. I was not referring to anyone’s religious practice but to the book itself, the Bible. Here is how it begins (this is KJV, but every translation I checked says “God”):
[1] In the beginning God created the heaven and the earth.
[2] And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters.
[3] And God said, Let there be light: and there was light.
[4] And God saw the light, that it was good: and God divided the light from the darkness.
[5] And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day.
It goes on like that. The being named is “God,” not “Yahweh.” There are no Christians in this picture. My point is that these books that are called the Old Testament are pre-Christian, that is, Jewish, but the God is one and the same, or at least a lot of people’s beliefs hinge on that point. There is no such thing as a “Christian” God as distinct from the God of the entire Bible.
