In the Hebrew Bible, various aspects of theism exist though monotheistic faith stands out, and the New Testament largely continues with Jewish monotheism. This Element examines diverse aspects of monotheism in the Hebrew Bible and their implications to others or race relations. Also, it investigates monotheistic faith in the New Testament writings and its impact on race relations, including the work of Jesus and Paul’s apostolic mission. While inclusive monotheism fosters race relations, exclusive monotheism harms race relations. This Element also engages contemporary biblical interpretations about the Bible, monotheistic faith, and race/ethnicity.
